At WhisperPower we are driven by a distinctive challenge: our systems are only seen as perfect when you can neither see nor hear them. All our innovation efforts are geared towards creating silent and low emission electrical power systems ensuring optimal freedom and comfort.


The power

It all started with the development and sale of an inverter that enabled battery current to be con-verted into a stable 230 volts in a safe and reliable way. “220 volts from the battery” was my catch-

phrase. In those days, that was something new; the in-land waterway captains in Europe were the first to be convinced of the benefits of no longer needing to purchase 24 V suitable devices.An important aspect was the fact that the device, unlike other inverters, did not breakdown under any circumstance.

In 2015 we, with WhisperPower, raised the bar a lot higher and this has been my biggest and most challenging project so far. Taking an existing process, manufacturing standard “old school” generators, and remodelling it in to a whole new “hybrid” business concept. During a market period which has carried a totally different dynamic since 2008, we have devel-oped a product portfolio that more than completely meets the demand for clean, smart, sustainable energy systems with maximum integration of all components. We are fairly ahead of the game with our “new school” solutions. We have successfully made the leap from “small battery and small inverter technology” to high quality high power inverter systems from 5 to 20 kW (!), which, when connected to advanced Lithium ION batteries, can support heavy 230 V or 380 V devices.

As usual in the development of new concepts, it takes time before customers are convinced of the benefits. Over the last three years we have seen a rapid accept-ance of our high power Hybrid Techno logy with our customers on land, water and road. In the automotive world electric or hybrid propulsion is a fast growing trend, partly due to tax incentives and stricter regu-lations in cities in terms of emissions. The maritime markets are more conventional and “switching” is historically slower, but the realization that propul-sion systems or energy systems must be sustainable, is slowly sinking in. Decisions by authorities, such as those in Amsterdam, to only allow zero-emission pro-pelled vessels on waterways from 2020 will certainly accelerate the process of changing over to electric or hybrid. WhisperPower is ready!

Hybrid Technology

Our hybrid technology basically comes down to the fact that we provide energy to locations where there isn’t a connection to the grid, in an extremely durable and often more economical manner. This is something we also apply to propulsion systems for yachts and small commercial vessels. We ensure that the diesel engine runs as little as possible and draws energy from a battery bank charged by solar power or wind turbines. Should the engine need to be started because the energy can’t be provided by the sun, wind or the battery bank, our hybrid technology ensures that the engine runs at the right speed and delivers maximum power. This means that no energy is wasted as happens with conventional systems where diesel engines are mostly only partly loaded.

You can see, the manu-facturing industry still exists in our country”, says director / founder Roel ter

Heide meaningfully, as he showed ‘Jachtbouw Nederland’ around his

company in Drachten. And indeed, the shop floor is buzzing with activ-ity and lots of generator sets are being assembled. Alongside the assembly department there is an extensive in-house testing centre, where all devices are mercilessly subjected to a comprehensive, three hour long test cycle. Only once they meet all the require-ments, are they allowed on to the customer. Quality comes first. They are also busy tinkering in the research & development department, albeit in a more virtual way. There, they make sure that the continu-ously improved WhisperPower systems also get smarter. WhisperPower develops and manufactures, in addition to the diesel generators, a wide range of power electronics: bat-tery chargers, inverters, inverter / battery charger combi’s and DC-DC converters. Some forty people

work at the Drachten headquar-ters; the company also provides work for a number of workers from community employment schemes.

Various marketsWhisperPower operates in various markets such as the automotive section, industrial and civil engi-neering world and the maritime sector. Vehicles require sophis-ticated compact solutions, for example for refrigerated transport, ambulances, satellite trucks and

campers. For industrial and civil engineer-ing it is about country-spe-cific projects: from tempo-

rary power sources on building sites to permanent power supplies in remote areas without a perma-nent power supply. An important market is the maritime sector, accounting for approximately 55% of turnover; WhisperPower works with both small commercial vessels

Worldwide network

WhisperPower has extended its Premium Service Partner network for the maritime market in the Benelux region where, customers can also go for a ‘health check’ of their system at a fixed rate. All system critical parts are inspected and checked. Worldwide, the company is represented in around fifty countries. There are company branches in Germany, England, Spain and Portugal (from which the South American market is also served), China and New Zealand. In addition, there are a number of franchise partners that have the right to use the name, including, amongst others, in Russia. In order to operate in the Russian market, WhisperPower must comply with the Russian River Register. An approval which carries a twice annual audit from Russia. According to director Ter Heide, ISO certification is the following goal.

systems are speed adjustable. The number of revolutions per minute is tuned to the needs at any spe-cific moment. That minimizes the vibrations on board. The genera-tor provides the required power and stops once the inverter takes over. This limits the running time and increases the ‘silent time’. Ter Heide: “Our devices can take more than those commonly found on the market and have hardly any restrictions in power; we have pushed the limit to 500 kW. The connection method is crucial, especially with larger equipment

WhisperPower developed this hybrid system for a 106 Ft yacht

From right to left: 2 x WhisperPower Hy-Gen variable speed generators each 150 kW, parallel 300 kW.

In the mid-dle, is the cabinet containing the DC connectors and fuses for the 750VDC bus coupled with the water-cooled Hy-Convert converters and the Hy-Invert inverters (for the 3 x 380 V three-phase power supply). Far left: two 40 kVA mains transformers for the vessel’s shore power connection. This equipment ensures the correct frequency and voltage on board wherever the boat is in the world, without the need for a frequency inverter.

and yacht building. “We provide everything related to electricity, including power generation, ie generators, with Dutch yacht build-ing being an important market,” says Ter Heide, “we are relatively young, yet trusted.” He himself has a long record of service in ‘power land’. His name is inextricably linked originally with Victron En-ergy and then later with Master-volt. In terms of this company, of which he himself was a principal shareholder, in 2007 he took over the generator division. Ter Heide: “Since 2010 I have been building

towards a systems-house that de-livers a complete range of electrical components, with the generator as its core.”

Short running timeThe mobile power demand is high and trends suggest that they will only increase. The present-day boaters will indeed be separated from land and enjoy their freedom, but then whilst maintaining the comforts of home. Ever more devices and ever heavier power consumers appear on board, from espresso machines to air condi-tioning, induction cookers and even steam ovens and dishwash-ers. Consumption is referred to in professional circles as “hotel load”. With so much energy consump-tion, turning the power on is inevitable. And with that comes a few hours of noise, smell and vibration. Or at least it does with old configurations. WhisperPower has tackled that inconvenience. Ter Heide: “Our aim is to develop systems that produce as little

disruption as possible and deliver optimum power for comfort with a short running time. If you enjoy your peace, any engine noise on board is already too much. We have integrated so many innova-tions into our systems, that we refer to it as ‘new school’.”

Demonstration vessel

WhisperPower has an effective means of showing their products to water sport enthusiasts: the demonstra-tion vessel Independence. This Sturiër CS 555, built at Volharding Staveren Shipyard, is equipped with varying different systems. The engine room is set up with a number of systems including: a Genverter 2, three work-ing DC Power Cubes 24/150, run in parallel, ensuring that the batteries are charged quickly through the Gen-verter generators. An AC PowerCube 24 / 14 000 inverter with 14 kVA to make sure there is a constant 230 V / 50 Hz voltage. Isolation transformers, a Piccolo and a standard 25 kW generator with PTO (Power Take-off).

of an alternator in to the flywheel, a feature also applied to the other compact Genverters, saves considerable space. Moreover, the applied super-magnets (perma-nent-magnet alternator) render it highly efficient. The Piccolo has an adjustable RPM and in combina-tion with the sound enclosure and the optional baseplate, noise and vibrations remain well contained. For the other Genverter models WhisperPower uses Kubota and Mitsubishi engines and for heavy duty systems, there is also the option of other brands, including Steyr diesel engines. WhisperPow-

er’s fixed speed generators are still in great demand on small com-mercial vessels. For the consumer market, WhisperPower offers its Orange Label; a range of prod-ucts distinguished by the colour orange. Increasingly, refits are be-coming an interesting market for WhisperPower. understandable as it is more efficient to replace outdated electrical systems in full with a contemporary version that is tailored to today’s interfacing, CanBus and NMEA 2000. In short, WhisperPower knows how to find markets which result in growth. www.whisperpower.com

on board. High currents are drawn from the battery when you go from lower to high voltage. This means resistance and that causes heat. Something that needs taking in to consideration properly. We therefore apply multiple connec-tion techniques. Heat also affects the durability of the inverter and battery charger. We work largely with power electronics based on high frequency technology and therefore it is important that we control any produced heat well. We call it ‘Running cool’.”

Minimizing charge timeIn addition to the speed control, connection methods and tempera-ture control, protection is also a key word within the ‘new school’. Charging batteries is a delicate process that, with the Whisper DCPowerCube, is fast and efficient. More and more Lithium-ION tech-

nology is being applied, so that the charging time is further reduced. That saves running time, and therefore pollution. Ter Heide: “We are currently doing a lot of projects in Italy and there, to a large extent, they go by ‘No diesel at anchor’. However whilst anchored they still run the washing machine and air conditioning. With the technology we have developed, a lot of power can be taken from the sufficient buffer stock.”

Complete packagesHe continues: “We supply ship-yards complete packages and all electrical components. In that respect we are also a logistics ser-vice provider. To give an example, for the new 67 Ft Hanse yacht we developed a complete system. With our systems it is possible to plug in to any mains socket wherever you are in the world, just as you can with an iPhone charger.” Ter Heide states that the biggest growth is in the sector for vessels upwards of 24 meters. WhisperPower also supplies hybrid propulsion systems. For the J-Class yachts, WhisperPower has supplied all-in-one systems: generators combined with electric propulsion that simultaneously generate electricity while sailing. Therefore there is always enough power for a night at anchor. Re-

cently, a WhisperPower Genverter system of more than 100 kW in combination with a 50 kW propel-ler shaft was installed on a 46 me-ter yacht designed by Hoek Design Naval Architects. In collaboration with Diesel Center Italia, one of the main MTu distributors, Whis-perPower developed a system as ‘eco-mode’ for fast motor yachts. Ter Heide: “It is a parallel hybrid system with an electric motor that is integrated into every drive train. These are fed by our Hy-Gen Gen-verter systems of 150 kW each, which take over the propulsion and ensure a speed of 10 knots. At the same time, the system provides enough power for the hotel load.”

Compact and powerfulIn contrast with that brutal force, stands the small, but powerful Piccolo, which was introduced last year. With its compact dimensions of 52 x 47 x 45 cm and weighing 68 kilos, this generator can be built in to numerous boats. It delivers 4 kW of power, and thanks to the use of a special inverter (PMG) in the output, the voltage and frequency remain stable regardless of speed. The heart of the Piccolo is made up of a one cylinder diesel engine, built by WhisperPower themselves. At 3600 rpm this WP1 is 4.8 kW strong. The integration

Things that work

Martijn Favot (47) is a happy man once the products

actually sold to customers. And that is happening

more and more. This is what Martijn, an old hand

when it comes to the energy world, had to say.

1514


You have been working in this sector for a good number of years already. What is so attractive about it?

Yes, I’ve already served 15 years! I was with Mastervolt until 2007 and following a short break taken with another company, I came to the WhisperPower group. The market has changed considerably in this time. Something I measure primarily in terms of the product itself. We supply electric power systems for those locations where there is no permanent connection to the grid. The maritime sector is still the easiest market for us to de-fine, where the demand for energy is only increasing and the require-ments change. That is where, as a relative newcomer, we can come in and help which certainly provides me with interesting challenges. Plus of course the development of systems for different market sec-tors such as mobile and land-based markets is also rewarding. Never a dull day!

What has changed in the sector?

In the nineties we were really pio-neering when it came to inverters, battery chargers, generators with a new type of engine management and lithium batteries. Nowadays, we produce systems that can deliv-er much more power with greater efficiency, lower power consump-tion and much higher reliability. This has been led, to an extent, by the availability of proven technolo-

gies such as permanent magnet generator technology, where super magnets are applied just as is done on modern windmills, as well as stable lithium cells and robust power electronics. We are now seeing that traditional mechan-ics, such as those used in diesel engines, become the weak link more quickly than the electronics and energy storage systems them-selves. An important advantage of the new technology we are de-veloping is that the quality of the power has become much better thanks to the electronics and that we can apply inverter technology for large energy consumers such as electric motors, air conditioning systems, complete galleys etc.

Where do you see the limit for the application of inverters for example?

With the introduction of Lithium-ION as a power storage system, it is possible to store much more en-ergy in relatively small spaces and with reduced weight in comparison to traditional lead-sulphuric acid batteries. Lithium batteries can be charged up to 100% of the nominal capacity or discharged. Therefore you can “pump” in or withdraw much more power from the bat-tery. For us, a 5 kW inverter, for the larger marine or mobile systems, is seen as an entry-level model. We provide a 7 kW inverter when there is a 7 kW generator and the next size up is 14 kW. We are now working on a 20 kW three-phase inverter based on a single cabinet principle, suitable for 24 or 48 VDC. Our charge systems and gen-erators developed to go with this follow what we call the New School principle.

Can any company develop this technology?

In principle yes, but we see many examples of companies who can provide a new style for part of an energy solution but cannot deliver a complete system. You

need a lot of experience to oversee the entirety of a smart energy system. You are dealing with diesel generator technology, PM tech-nology, storage, charge technol-ogy, inverter technology, power management and monitoring and control. And then the components must also be installed well, which requires skilled guidance with the same applying to commission-ing. Then you have, for boats and “roaming vehicles”, the need for worldwide service. We can do all this, have years of experience in all these areas of expertise and have built a great network. We are also fortunate in the fact that we have the financial resources to maintain this kind of expensive R & D.

Why would the customer change and choose your new technology?

Firstly, customers want super-reliable systems requiring little maintenance, that are safe and do not break. WhisperPower / Hybrid Power fills this demand by seamlessly delivering rock solid products. The customer also wants to consume less energy and bring down the total cost of ownership. Noise and vibrations form another aspect. The user does not want to hear anything and if possible, would get rid of the diesel engine

so that they can live on a zero-emission basis at anchor or in port. The hybrid aspect - complete electric propulsion or combined with diesel - is something that is very clearly coming, in line with what was seen in the automotive industry. We simplify onboard in-stallation with our systems - fewer cabinets, fewer labor costs related to installation etc. For large yachts, for example, our system makes the installation of a shore power converter, costing between 30 and 50 000 euros, redundant.

I read a lot about the new Piccolo generator, tell us about it.

The Piccolo is our own success story and a prelude to the expecta-tion that fixed speed generators will be replaced by variable or adjustable speed generators. With the Piccolo, the customer is buying a high quality 4 kW generator, suitable for land-mobile or marine applications. They get 25% more electrical power with perfect volt-age quality so that all connected devices work with 100% certainty for a 25% lower price. That is innovation. Plus, the generator system is also 30 kg lighter and the noise level is much lower with far less fuel consumption. Easy money. Connection to other WhisperPow-

er components such as the inverter / battery charger combination and the control panel is plug and play and we offer more and more in an All-in-One cabinet set up, saving the customer a lot of money on the installation. This story also ap-plies to the two and three cylinder Genverter products.

How is it that the Piccolo is so advantageous?

First and foremost, it is a ques-tion of design. With this product we fully implemented the “design for manufacturing” principle. This results in a high quality product that is easy to assemble. We produce the Piccolo in our factory in Drachten. Thanks to the design and Lean by Kaizen production principle, we have a much shorter construction time. Then you get to economies of scale. We focus on substantial volumes per month which helps on the purchasing side, handling etc.

What developments have you experienced yourself in recent years?

In the past, I have gone through every conceivable technical posi-tion, from junior product develop-ment to product manager. I have also designed systems for small

and large yachts, which of course much more practical work. I have also led many outsourcing projects. I have worked as a developer of power electronics and for several years, was responsible for the en-tire industrial design in a medium-sized company. At WhisperPower, in my role as Technical Director, all this comes together. I have a good overview and have a lot of specific knowledge in every field in which we operate. Fortunately at Whis-perPower, we still have the scale of business where project manage-ment, engineering and supply chain activities can be combined within our multi-disciplinary teams.

You, WhisperPower, make your own inverters. They are pretty big things!

From the market itself there is a growing demand for more silent power for serious loads including air conditioning units. In general, the power consumption per device is decreasing. Air conditioners for example are becoming more economical etc, but the actual number of devices is increasing. At WhisperPower, we are pursu-ing the inverter technology with heavy consumption as a main goal. We are now making heavy duty inverters which are characterized by a perfect, stress-free connec-tion technology on the DC side and sublime behaviour in terms of output voltage quality, start-up performance, efficiency and noise level. Perfect cool running units.You can compare the AC Power Cube with the development of the motorcycle. The old, pounding and vibrating one cylinder motorcycles that were previously made in Eng-land have been pushed out of the market by modern multi-cylinder engines that are made in Japan. This is similar to the battle that we have taken on, moving over from old, transformer-based inverters with a large ripple, low efficiency and an unpleasant noise level to a smooth running AC Power Cube. The new school all the way!

Stijn de Wit:

The future is now

Stijn de Wit has worked at WhisperPower’s sister

company, Hybrid Power Systems BV, since january

2015. We asked him about his experience with the

company so far and his plans for the future.

What did you do before you started with your current employer?

I spent more than 12 years at Holland Nautic, a company in Apeldoorn, which for many years was an importer for Raymarine and in the last few years, repre-sented Simrad / Navico. I worked initially as an after sales engineer for the various communication and navigation equipment and later as a product manager and project leader for the implementation of major projects including, amongst others, mega yachts.

How did you end up in the maritime world?

My father was an owner of a marina in Meppel for many years so I was pretty much born between the boats! As expected and rather typically, I am drawn to everything maritime. During my school days I did a number of technical jobs on board of yachts in Meppel and Zwartsluis, including working for the Kranerweerd. During my studies, I did a placement at Hol-land Nautic and I just sort of stuck around, in a positive sense!

You switched to a firm with very different activities, what is the background to that?

In recent years, I began to get itchy feet. I wasn’t really getting much further with my previous employer and the position of a European importer of these sort of products is increasingly under pressure as

manufacturers move increasingly towards the customer directly. I started looking around and knew of the existence of WhisperPower. In fact, a former colleague of mine, Rene van Miltenburg had started working there a year earlier, mak-ing the switch to another company after 27 years. He had good words to say about the company and the management. I saw a new field in which I could develop myself further.

Electrical systems are different to the field from where you have come from.

Yes, that’s correct but the transi-tion has actually gone very well. I was immediately thrown in at the deep end and “let loose” on a couple of projects that I have completed with good results. It’s all going well: mostly the cables are thicker and the voltage is slightly increased. Previously I dealt with 24 V but now 800 VDC, with am-perage up to 600 amps.

Do you still have to undergo further training?

Sometimes I pick up the books of an evening and I make sure I listen well to my “teachers”, that helps a lot. I have just successfully com-pleted, as project leader, the first of two hybrid installations project which were sold last year. It was an ambitious project where the bar was set very high: the develop-ment, manufacture and supply of a complete hybrid power / propul-sion system for a 36 meter motor

yacht. We developed, in a short space of time, a diesel-electric propulsion system of about 250 kW capacity as a sort of “Eco” naviga-tion mode for this type of yacht. We developed two super-quiet new generation diesel generators, each 150 kW, which alongside the propulsion, also had to feed the on board power supply. For night use, we developed a concept that, with-out the use of generators, enabled the yacht to remain completely cool via the air conditioning system which was connected to a 40 kVA inverter system. So even without running engines, there was still complete comfort.

What was so complicated about this system?

Firstly, most of the components were not in existence so we had to develop them first. During the pro-ject we had to work with a Dutch contact and a few Italian subcon-tractors and integrate everything with bus technology. And all at an Italian shipyard, San Lorenzo, where they work differently to here in Northern Europe. That took some getting used to. Let’s just say communication, planning and making appointments there is something else.

Tell me more about your experiences with that Hybrid Project

The main objective of the project was to provide the SL 106 with a speed of 9 knots using electric motors, supplied by the Italian

company Auxilia, which were installed between the gearbox and 2 x 2000 kW MTu propulsion mo-tors. In Italy they call it a “comfort” mode, whereby the ship can cover large distances quietly and above all economically and can enter bays. This can result in a saving of many tens of thousands to more than a hundred thousand Euros per season. We installed two 150 kW WhisperPower HyGen silent generators which together provide up to 300 kW, 240 kW of which is used for propulsion and at least 60 kW for the “hotel load”. It was a wonderful experience during the sea trial to sail super silently on e-propulsion. You could only hear the water and still, we were going at nine knots. The boost function, so adding the e-motors to the MTus also worked well. We achieved a speed of almost 50 knots. The semi-electric sailing was also a success: with the MTu on one propellor and electric

motor on the other, the diesel consumption was 40 liters / hour at fairly decent speed. A second objective was to make the ship “quiet” overnight whilst still maintaining comfort. The chal-lenge here was the fact that the on board power supply was set up as three-phase 400 volt, as is typical for this type of yacht,and there were no standard DC-AC inverters available on the market. We devel-oped a 10 kW three-phase inverter that enabled the air conditioning units, refrigerators, freezers etc to continue to run from our 24 VDC WhisperPower Lithium-ION battery bank. In total, we loaded 40 kW on to the inverter. It worked perfectly. As a backup and for charging from the shore power, we installed two 15 kW “Piccolini’s” (Genverter 15 kW) with quite a few DC Power-Cube charge modules that quickly and completely charge the bat-teries either when shore power is available or via the small Genverter

units or the larger Hy-Gen 150 kW generators. The major challenge was linking all devices, including the non-WhisperPower products, via a central CAN bus system and then programming the power management system. This part was carried out by the company Navico and they got the job done in an admirable and effective manner.

This project has now been completed, what is in store next?

We have new hybrid orders in waiting, including one from Baltic Yachts in Finland plus there are many enquiries. Furthermore I am also the product manager for the instrumentation that WhisperPow-er calls WhisperConnect. We have a large number of devices that we want to link together via a cable bus system based on a simple plug-and-play operation. With this, I can absolutely indulge my ambition to deliver perfect systems.

Do you, Hybrid Power, develop everything yourself?

We work together with special-ists so that we can speed up the development process. Yachtcontrol from Hattem is our partner in the WhisperConnect project. They have a great software team and are very skilled in designing touch screens. An additional advantage is the fact that they are also involved in the development of displays for compa-nies such as Webasto and Kabola. We also work with other specialist companies such as Empirbus and Naviop Italy. unity is strength.

What do you see as your biggest challenges at Hybrid Power / WhisperPower?

Steeler Yachts was founded in 2010 as a continua-tion of my activities at Antaris (nowadays known

as Aquatec) that I had set up 10 years earlier. Alongside polyester mass production of boats and day cruisers, steel yachts were also built there on a limited scale. With Steeler Yachts I am building on that concept. A big advantage of build-ing with steel and aluminum is the fact that there is no need for costly molds to be made plus we are able to respond quickly to customer requests. We build 100% of our yachts customized for the client.

So people who want to go and buy a standard boat from stock go to a production builder such as Bavaria

or Beneteau but boaters who want something unique, made complete-ly to their needs, come to us.

Often people have been saving up a long time to buy a boat and therefore, they want maximum input in how it turns out and want to be involved in the build process in detail. With 13 boats under con-struction at the moment and over 30 produced over the last 4 years, we must be doing something right.

What are the trends that you observe?A few years ago, we saw a shift towards 15 meters but that then went down to 12 meters, and more recently, we have seen it head back up to 13 meters. 50% of what we build is in aluminum. The big ad-vantage of that is that it has similar properties to steel but can sail more quickly due to the reduced weight. We now have a number of yachts that go to the Mediterranean and so are delivered with full air condition-ing. For all our yachts, it is usual that long trips will be made, so onboard comfort is key. It is for these rea-sons, that for our complete range,

Hans Webbink is a name that is hard to imagine the Dutch maritime

world without. A born entrepreneur with a fighting spirit, who

dared, in difficult economic times, to start a completely new

business from scratch - Steeler Yachts, based in Steenwijk. This

infamous and inspirational industry figure shares his story.

we use WhisperPower systems which can also be connected to the different touch panels for example, Yachtcontrol or Raymarine.

Last year you received a European prize for the Panorama boat. What does 2016 have in store?The Steeler NG 43 has been nominated as European Boat

of the Year 2016, so I hope to come up trumps. It’s a pretty fast aluminum yacht equipped with Yanmar engines and a roll damping stabilization system. Last year we focused on space and the “house boat” experience. As we head in to 2016, we are going to focus on design and game changing efficient planing”.

Hans Stacey

Innovation at Starin BVHans Stacey is a famous name in the rally world. In 2004 he drove his first

Paris - Dakar rally in a DAF truck. He went on to drive this rally 3 times with

his own MAN truck team and later with the MAN factory team up until it was

relocated from Africa to Latin America. In 2006 he finished 2nd in the Dakar

rally. In 2007 he was the last Truck class winner the original Dakar in Africa.

In 2008 he and the MAN team were the winner of the Central Europe Rally

and the Trans Orientale rally from St.Petersburg to Peking.

From 2012 to 2015 Hans Sta-cey was part of the Petronas Iveco De Rooy team and in 2012 came second behind

his nephew Gerard de Rooy. “Over the last few years I have only had daytime victories and had all sorts of problems like punctures etc. But I keep going. I am now busy again training for the Dakar 2016. I am driving for the new EVM team, which stands for Eurol, Veka and

Man. Eurol, from Nijverdal, is a major oil company who hand out a lot in terms of sponsorship. I am feeling super fit and am going to go for it.” Says Hans Stacey.

High-tech truckIn addition to being a successful sportsman, Hans has also earned his stripes in the business world. “Exactly 30 years ago I started Stacey Olie with 10,000 Guilders

from my childhood “Zilvervloot” savings account. Years earlier, I had a petrol station but just couldn’t compete during the oil crisis with the big groups such as Macro throwing their large discounts against me. With a lot of hard work, Stacey Olie BV has become a great business and is in fact where WhisperPower gets their oil and coolant from. In 2013, I sold the business. I am now active as an

investor in other sectors and one of the companies I am involved in is Starin BV. This new company, based in Eindhoven, specializes in injecting and sealing leaks in wells and man-accessible and man inac-cessible sewer lines.Through a new innovative injec-tion method, multiple leaking pipe connections or longitudinal cracks in sewer pipes can be filled-in in a day. This is achieved with a high-tech truck which is equipped with all of the tools required on-loca-tion. This includes a smart robot system which is used to inspect pipelines and repair where neces-sary. This all takes place without the need to dig up a road resulting in huge savings.” Says Hans.

“I asked the technology sup-plier from Germany to install a WhisperPower hybrid power system so that where needed, for example in urban areas, could do my work without running engines

or generators. That objective has been achieved. The system runs perfectly and can operate for eight hours without the engine running. We have since further expanded the fleet with a Mercedes Sprinter used for the preliminary examina-tion of the sewage channels so that we can work as efficiently as possible.” Says Hans Stacey..


YachtControl

Based on trustWhisperPower has professional engineers on staff,

skilled and experienced in their fields. However, as

so much has had to be developed in a short space

of time, WhisperPower has also collaborated with

specialized companies where needed to bring in

supporting key skills and experience. One such

company is Yachtcontrol from Hattem, with whom

the company has had a successful and good

cooperation with for several years.

Victor van der Louw, owner / director (47) of Yachtcontrol, deliberately made the move over

from the IT sector to the marine market sector a number of years ago. “In 2006 I founded Yachtcon-trol from my exisiting business

DataDate, a sort of recruitment agency for the IT sector. I was looking for a suitable device for communication and navigation for my sail yacht but it wasn’t possible to buy one off the shelf. So, I went on to develop one myself and that is how Yachtcontrol emerged. Now,

almost 10 years later, I have a suc-cessful company which specializes in tying together, to put it bluntly, navigation and communication equipment, digital switching and other essential functions on board. We can make sure that all information is clearly displayed on a screen and can also be remotely monitored. We also develop prod-ucts for companies like Webasto, Victron Energy and in more recent years, we have been doing a lot with WhisperPower. Together, we develop the readout screens for the various energy systems that WhisperPower sell in the maritime and mobile markets. As a result we have also, in the wake of Whisper-Power, made the move in to the mobile market.

What is your business model?We are still working primarily in the Benelux region, where we have our hands full. We do refits directly with the client and for the rest, we work with the yacht builders. We listen to the wishes of the customer and then come with a complete solution.In the future we want to increase our geographical area but we are

still small, there are only seven of us in total. We think that the cooperation with WhisperPower can bring us a lot and vice versa - electricity is becoming increas-ingly important on board and that

is what they are good at it. For WhisperPower, we develop the links that are necessary to allow the electrical components to talk to each other which all comes together in a kind of automatic control.

What do you see changing in the future in the industry?We will see a move much more to-wards mobile and cloud computing

applications and in turn have less onboard computers. I am talking about internet on board, entertain-ment and TV, all monitoring and surveillance functions etc. This is indeed not only convenient but also cost effective. 5 Victor van der

Louw: Together, we

develop the readout

screens for the

various systems that

WhisperPower sells.


Combimac:

Low profile but high tech

Combimac is a typical no-nonsense company exclusively

focused on high-quality engineering and manufacturing quality

components for offshore and commercial shipping

Combimac, based in Emmen, is a specialist company in the field of the development and

production of electric motors, permanent magnet alternators and industrial fans. The com-pany was founded in 1919 and moved to Emmen in 1956, during

a time when the northern part of the Netherlands was still an area of development in combat-ting unemployment. At the time, many businesses from the west of The Netherlands moved to the northern areas. Since 1993, the company has been owned by both Helmoed Robben and Michael de

Zwart. We spoke with Helmoed about the company and the col-laboration with WhisperPower

What is that makes your company so special?Our core business is in designing and manufacturing special electric motors with capacities from 1 kW to 1 MW as well as special ATEX certified fans for, amongst others, the biogas industry and offshore industry. Traditionally, we used to be a main supplier for the Dutch navy, submarines, minesweepers and destroyers that require very specific components. Over the last 20 years, not as much has actually been built in our own country so we have shifted our scope to Asia,

then we have, in close cooperation, developed a whole range from 50 kW to 150 kW. We have also been involved in their smaller systems. It is a solid collaboration with a lot of prospects.We first came in to contact with the yachting sector a few years back when we supplied the 300 kW electric propulsion motor for Ethereal, a 58-meter sail yacht built by Royal Huisman Shipyard in 2009. This was the first sail yacht to be fitted with an advanced Hybrid power / propulsion system.

How is business now? You name the offshore sector as a major market, is that still going well?Due to the low price of oil, all in-vestments in new gas and oil instal-lations are under pressure. We see that instead, the navy export market is growing. In terms of business, we find new customers through word of mouth and do limited advertis-ing. We do exhibit at SMM, one of the biggest maritime shows in the world, which takes place every two years in Hamburg but in general, we keep a low profile.

Innovation strength

Customers come to us with technical challenges, products that have never before been made: think of dimensions, efficiency, shock resistance, for example for navy ships, dura-bility etc. We are asked to find the very best ‘top’ solutions. Meeting these requirements is our strength and our innovation. It is also the reason for our existence; when another company cannot make something, often we can. Despite a decline in the offshore sector, we remain positive about the future.

Local expertise

A powerful, dynamic group of companies

Joost Krebbekx is a senior consultant in the field of Innovation

for Berenschot, a management consulting firm based in Utrecht.

With 350 employees, Berenschot is one of the larger companies

in this field in The Netherlands.

In addition, Joost Krebbbekx is also involved with the Innovatie-cluster Drachten (ICD), a group of innovative companies based

in and around Drachten, one of which is WhisperPower, aiming to put the region on the map in terms of innovation and high-tech knowledge and skills. Joost Krebbekx explains his involve-ment and experience with the ICD in more detail and what this means for the local industry and economy.

“Since 2014, I have been a pro-gram manager at the ICD. I live in Heerenveen, just a few minutes from Drachten by car. I devote approximately 2 days a month to

production takes place accord-ing to given specifications. These companies design and produce their own products and services meaning there is a real manufac-turing industry here.”

What are your plans for the future?“We want the Cluster to grow grad-ually with 2 to 3 companies joining per year from the northern region, say from within one hour’s drive from Drachten. We will look at whether the company in question is active on an international level, if they themselves are creative and whether they meet our high tech criteria. With this vision, we see the Cluster growing in to a power-ful, dynamic group of companies.”

WhisperPower is proud to be one of the thirteen innovative compa-nies forming the ICD. It is a public-private partnership that has been active since 2011 and continues to expand and strengthen bringing together extensive knowledge and experience.

the Cluster and the main tasks are implementing the agenda, devising strategy plus involvement in the creative process of looking at how we can better put the ICD on the map. A nice job. It’s dynamic and rewarding.”

What is your experience so far with the ICD?“Now is the right time to let these partnerships develop and grow. unlike eight or ten years ago, the companies are now ready and people realize the importance of collaboration to help advance the national economy. In the past, companies operate according to the “build to print” principle. Today


Innovation efforts

Sustainable solutionsAt WhisperPower we are driven by a distinctive challenge: our

products are only seen as perfect when you can neither see nor

hear them. With this in mind, all our innovation efforts are geared

towards creating silent and vibration-free electrical power systems.

Those that do their work without interruption. That take advantage

of renewable energy sources to reduce emissions and

costs and enhance efficiency.

Smart off-shore powerA perfect example WhisperPower’s ability to combine renewable energy sources with traditional technology can be seen in the systems designed to operate unmanned drilling platforms. An example of this is the company’s recent project carried out for Nederlandse Aardolie Maatschappij BV (NAM), a joint venture between Shell and Exxon, whose head-quarters are in Assen in the Netherlands. NAM has searched for and produced oil and gas in the Netherlands since 1947, both onshore and offshore. Their main objectives are to sustain production from existing fields, explore and develop new fields, and obtain more gas from existing fields by using innova-tive techniques. NAM employs over 1700 employees and conducts operations in a safe, sustainable and efficient way. WhisperPower has engineered and supplied NAM with a system that will provide a drilling platform with sustainable, solar based electrical power. Rik Visser, one of WhisperPower’s senior technical engineers, has been following the project and has also spent several weeks at sea on the platform for maintenance work.

Security systems which protect property from criminals and ensure safety for people and the environment is a growing busi-ness worldwide. WhisperPower is also involved in this market for unmanned, temporary security systems.

A unit for observation consists of an advanced camera system and detection equipment which wire-lessly supplies information and feedback 24/7. The central moni-toring room registers every event occurring on the site. These units are powered by WhisperPower’s maintenance free batteries and a back-up charge system made up of a 1 cylinder Genverter and a DC PowerCube connected to the fly-wheel. During periods of storage or when the units are not in use, the batteries are maintained by the DC PowerCube’s battery charg-er. Solar panels are the primary power source which work very well during the summer period. One of the companys supplying security systems for remote areas and building locations is Bouwatch. They provide both mains powered units, which can be connected to utility power or a generator, as well as off-grid systems powered by solar panels and WhisperPower’s diesel based back-up systems.

He explains:“Before we, WhisperPower, could start this project we had to obtain our offshore license, which we did. We went on to supply the first system in 2014. It ended up being a kind of “fast tracked” engineering project as NAM wanted to install the system within a very short time frame. Their main objective was to reduce the costs by having 24/7 surveillance rendering the need for staff on a boat close to the platform obsolete. Fur-thermore, they wanted to reduce the fuel and mainte-nance costs of the generator system. We put a 12 kW solar panel system together, mounted on a frame, to charge 2 x 1500 Ah 2 V Gel cells and a 1 x 1000 Ah set. The WhisperPower 10 kW, 24 VDC to 230 VAC inverter system powers the entire AC network and includes ac-curate remote system monitoring. During low energy generation days, for example during the winter, a back up diesel generator automatically charges the battery if the DC voltage is too low. The system works perfectly and considering the harsh circumstances, holds up very well. We are now preparing additional similar systems for the same customer”

Non stop power for surveillance units


Expansion in Spain and PortugalAfter some challenging years, the market for WhisperPower in this area of the world is growing again. Managing direc-tor and part owner of Whisper-Power Iberica, located in Gan-dia close to Valencia, Patricio Blanco, is now adding strength to the company by hiring more staff. Kyla Frances Nagle came

on board in early 2015 to take care of the back office plus new salesmen are now starting to visit customers on a nationwide base. The Spanish subsidiary also covers the Baleares, Canaries, Portugal and countries in South America. The “ new school” power systems are selling well now, especially into the retrofit markets. A traditional 20 metre Motor yacht was recently finished by Multinautic Servicios Náuticos S.L. in Villa Nova Grand Marina in Barcelona. A 14 kVA AC PowerCube operates the entire 230 V 50 Hz onboard network including high power consumers such as the Webasto WB 300 kW system heat and cold system of 50,000 BTu. A WhisperPower battery bank consisting of 2 volt cells is charged by the Genverter GV/3 with 2 x DC PowerCube. During navigation, batter-ies are maintained by 2 x DC Beltpower 150 Amp, fitted to the 2 propulsion engines.

The mobile market offers good growth opportunities. A lot of projects have been delivered including systems for food trucks. Santilles Icecream, operating in Andalusia, has ordered the third system from WhisperPower to operate another Mobile Ice Shop which supplies the beaches in the South of Spain from May to October.

New Battery charger/rectifier rangeCommercial vessels, high-end recreational vessels and off-shore plat-forms carry an enormous amount of electrical and electronic devices that require a safe and non- stop power provision. WhisperPower’s Supreme professional battery chargers combine three vital functions. Smooth, ripple free multiple step battery charging, a power supply func-tion to buffer DC appliances in a direct way and a complete alarm and monitoring device for the entire 24 VDC system. In early 2016, 40 and 60 Amp models will be introduced with 80 and 100 Amp versions fol-lowing later that year. Lower power units from 15-30 Amp will follow. All models are produced to operate on a 90-265 VAC / 50-60 Hz input and will be fitted with three separate outputs.

Nautic AfricaNautic Africa is part of the Nautic Group of Companies with its head office in Cape Town. The company is posi-tioned as a leading shipbuilder and maritime services provider in Africa and beyond, using relationships, technology and skills to put their vessels at the fore-front of modern shipbuilding. WhisperPower is proud to be one of their key suppliers for electrical parts such as WhisperPower diesel generators. These are installed in workboats, patrol boats, search & rescue vessels and other craft. Nautic Africa’s boats and ships are sold worldwide basis. WhisperPower supports all the supplied and installed systems with their local service dealers.

WhisperPower NorwayWhisperPower Norway, located in Oslo, is WhisperPower’s dedicated distributor for the entire product range and for all markets in Norway. In addition to marine business, the company is also exploring land based op-portunities as well.In Norway, there are many leisure homes, cabins or “hutte” as the Norwe-gians say. They love to travel to these places, which can be found close to the sea or in the beautiful mountain massif which Norway is surrounded by.Norway is fortunate to have hydropower electricity as a natural resource which is therefore also inexpensive. However, in a country like Norway with so many inaccessible parts, there are many places which are not connected to the main grid. In order to obtain the comfort from home, WhisperPower Norway is now offering smart power packages. Systems were recently supplied to an island in southern Norway where there are more than 1,000 cabins living off the grid.Clients require the best system, from the most innovative supplier, ensuring operational reliability, lowest cost of ownership and minimal audible noise. In WhisperPower they find the right partner. The WhisperPower systems operate the kitchen equipment, entertainment, lights, tools and heat. System specification: Genverter W-GV / 2K - 2-cylinder, WP-DC PowerCube 24V 150A, AC PowerCube 24/7000 inverter for 230 V AC appliances and a battery bank 12 V 1250 Ah battery bank (2 volt cells). Required generator running time 120 hours/ per year.

GermanyFor Dutch companies operating on an international basis, Germany is an obvious market to approach. We have been active in this territory since the beginning with growing results. We have recently founded WhisperPower GmbH in northern Germany, with the facilities being located in Schleswig. Together with our German business partners we are expanding the business in the various markets.

Mobile activities are growing. The food truck industry is important in Germany for local use and exports. Local markets, festivals and sports events all need mobile catering facilities which are equipped with proper food and drink storage and preparation systems. Catering vans are increasingly common on industrial estates selling food and drinks to company employees as is the door to door sales of merchandise to consumers.

WhisperPower GmbH supports these mobile activities with the ideal and correct electrical solutions. 230 V engine driven alternators (BeltPower), which produce power for direct use or to be stored in the batteries, have become one of the main products alongside lightweight Lithium-ION batteries and compact silent generators ranging from low power to many kWatts. Other applications of WhisperPower systems are demonstration vehicles, bank vehicles, medical trucks, ambulances, in fact any non-standard vehicle.

In a refurbished English style Ford Transit, a soft ice machine together with a cream machine, fridge and 3 Granizado Frozen Drink ”slush” machines are installed.They are operated by a 10 kW, 3 x 380 V inverter system connected to an AC BeltPower generator and a small battery bank. The system runs without any prob-lems in spite of the being operated in very hot circum-stances, close to the sea, 12 hours a day and non-stop for 6 months. In addition to this, WhisperPower is also the leading company in the supply of inverter based AC Power systems together with small fridges for medi-cal purposes to Spanish Ambulance builders.

Spain is one of the most important boating areas in Europe but the local boatbuilding industry has dis-appeared almost completely. A well known player is Menorquin Yachts from Menorca. Ten years ago they built over 70 boats a year but after the big crisis of 2008, their sales dropped severely and the company had to reduce activities. In 2011, Mr Francisco Sastre started to build the Menorchi-no series of semi-traditional semi-displacement yachts, from 34 ft – 54 ft. The company selected WhisperPower to supply the entire electrical systems for their boats, including “ new school” Genverter generators.

Our marine activities are growing as well. Ship-building companies like Fassmer GmbH (Berne, Northern Germany) use WhisperPower generator sets for their redesigned 28 m Search and Rescue vessel (SAR). This new 28 m rescue vessel and its 8 m daughter boat placed astern, are constructed as self-righting vessels and built completely from marine aluminium. With a maximum speed of 24 knots and a high-performance propulsion system, this 28 m Search and Rescue vessel is well-equipped for safe service in the German Bight. A SQ 27, 27 KVA, 1500 rpm, GL certified generator provides the power.

Pleasure boats is another emerging market for Whis-perPower. Participation with the main boatshows (Hanse Boatshow, Boot Duesseldorf, Interboot, Ancora) is helping to spread the name and demon-strate the extended portfolio. Companies like Hanse Yachts have selected WhisperPower systems for their new 675 sailing yacht. These systems provide worldwide plug-in facility, full comfort even with limited shore power and zero- emission power to operate the airconditioning.

Menorchino 34 ft

InternationalWhisperPower International BV, the holding company of WhisperPower BV, Hybrid Power Systems BV, WhisperPower Iberica, WhisperPower Germany, WhisperPower Pacific and WhisperPower China, is enjoying a very healthy year so far with revenue growth of over 40%. This positive performance has predominantly benefited from the investments made in new technology over the past 5 years and the establishment of a qualified global network consisting of sales offices, distributors, premium service dealers and install-ers. The Group’s workforce increased by 20%.
