• Plug & Play modular micro-grid in a box

• Ability to supply 100% clean energy with reduced carbon footprint and real estate requirements and higher reliability than solar/battery hybrid solutions

• Autonomous, intelligent, and efficient multi-source energy generation and battery integration, ensuring guaranteed continuous power at a reduced cost against fossil fuel alternatives

• Significant tower infrastructure savings - Elevated tower (lattice or monopole) with low vibration provides co-location platform for telecommunication transponders, lighting and video recorders

• Modular scalable design to meet growing energy demands, with ability to swiftly deploy for temporary or long-term use

• Containerised (20ft standard containers) for ease of transport, access and installation in remote areas with no requirement for heavy lifting gear

• Low maintenance and long life with remote performance and condition monitoring

• Secure continuous energy supply with a robust installed wind turbine, the main components stored in the locked container and tamper-free solar, the Crossflow IES is protected against pilferage and vandalism

Crossflow INTEGRATED ENERGY SOLUTIONS (IES)

Crossflow has developed an unique IES that combines its own bespoke wind turbine and supporting energy management architecture with other forms of energy generation and storage to provide resilient, sustainable and commercially attractive renewable energy in remote off and weak grid locations.

The principal power output is used to deliver a consistent source of electrical energy to meet the demand of the primary load consumer with a secondary power output available from excess power generated from solar and wind sources.

• Primary Load 1 = Turbine + IES self-power

• Primary Load 2 = Primary Customer• Secondary Load = Other users

• Energy capture shield enhances efficiency and power output

• Low rotational speed reduces fatigue and ensures extended operational uptime and longer lifetime

• Specifically designed for remote locations with robust engineering, reliable design and ease of construction and maintenance

• Self-starting turbine, generating at low wind speeds, enabled by a combination of high torque and low rotational speeds

• Ability to track and ‘spill’ wind to optimise energy capture, ensuring tolerance of high speed and turbulent wind conditions

• Simplified components ensure greater energy production minimising downtime and lowering maintenance costs

• Simple robust blade design and combined lift and drag modes ensure durability against extreme operating environments

• Reduced visual impact and greater opportunity to install at more sensitive sites, provided by shorter tower heights and tilt-down capability

• Significant, noise, visual impact and safety advantages due to ’Tip Speed Ratio’ significantly lower than three bladed alternatives

• High wind resilience due to design durability (max. 120mph) and tilt-down tower

• Hybrid lift and drag characteristics of the turbine avoids risk of damaging high-speed rotor run-away faults

• Quiet in operation, environmentally friendly to avian and chiropteran wildlife
