VSD Solar Pumping Systems Irrigation and Borehole Applications

Introduction

Tripple Hydro & Energy offers a complete range of pre-

assembled solar pumping systems that provide a solution for

a wide variety of pumping and harvesting applications.

Our VSD drives are enclosed in IP54 and IP65 all-weather en-

closures and are available in different size and panel varia-

tions depending on the control and environment of the in-

stallation. Your system ranges from 0.37kW to 400kW, de-

pending the motor size.

We offer 2 Options namely; Solar Off-grid or Hybrid Solar-

Assist. The Drives we use are superior to its competitors

manufactured in Brazil and is offered with 24/7 support.

When offering a solution we prefer to do an assessment to

find the most efficient pump size to reduce power consump-

tion and thereby solar array size and cost.

Benefits of using our VSD

Solar Pump Systems

Multi-speed: up to 8 pre-

programmed speeds

PID regulator: automatic control

of level, pressure and flow rates.

Ride-through: operation during

momentary loss of the power sup-

ply.

Skip frequency: rejection of criti-

cal or resonant speeds

S ramp: smooth acceleration /

deceleration

Hybrid VSD Solar Systems

The current standard changing form Solar to Grid

is by means of a manual change over switch in-

stalled. Our Hybrid Solution provides a true hybrid

pumping system which automatically blends grid

power or generator power with the core solar

power supply to ensure constant power to the mo-

tor or pumping system all the time. Thus working

similarly to a grid-tie inverter but with no feedback

into the grid.

When grid supply falls out during daytime hours,

the system will run only on solar power and when

overcast or poor sunny conditions occur the sys-

tem will automatically blend with alternative

sources available.

Solar assist also can be applied when limited solar

(PV) array is available and would supplement ener-

gy usage and as the solar array is expanded it au-

tomatically reduces electricity costs.

When we design custom systems the solar array

normally is factored according to client needs con-

sidering financial layout.

Remote Monitoring

Our solution provides comprehensive analysis, monitor-

ing & control of the multiple aspects of your water sys-

tems via a cloud portal.

For each system you can access live readings, historical

reports, and remote control of your water system.

Our systems provides a wide range of monitoring, con-

trol and data logging opportunities for:

• Remote or difficult to access locations

• Hazardous or critically important sites

• Long-term groundwater statistics

• Drought and water usage management

• Landfill and mine water supervision

• Flood and storm water management

• Water usage and flow rates

• VSDs & Pump Control Systems

• Irrigation Systems

• Mining

It provides monitoring for almost every aspect of the borehole. The

system monitors water level, flow rates, power used & number of

litres pumped. The system is also capable of optimising the draw-

down rates in order to protect both the pump & the well from over

pumping.

Features:

2G GSM Telemetry (integrates with polar cloud portal)

Solar Operating Hours

Specify your solar panel’s array according to :

Normal operating hours = 1.55 x pump’s Kilowatts

Early & late operating hours = 1.95 x pump’s Kilowatts

See below example:

Motor specification – 3kW 3 phase 400V 50Hz

PV panel specification – 45.65 VOC, 36.52 VMP, 330W

VSD specification – 800 VDC max, 450 VDC min cut off

Ideal input - 650 VDC on our VSD Systems

VOC-Voltage Open Circuit

VMP-Voltage Maximum Point

VDC-Voltage Direct Current

1)Determine the maximum amount of panels connected in series

for one string

PV panels (VDC max ÷ VOC)

– 650 VDC max ÷ 46.24 VOC = 14(PV panels connected in series)

2)Calculate the power requirements based on

“normal operating hours” (1.55[min] x pump kW)

– Total Power required = Pump kW x 1.55

– Total Power required = 3kW x 1.55 = 4500W

– Power per string = 330W panel x 14

– Power per string = 4620W

– Amount of strings needed = 4500W ÷ 4620W

– Amount of strings needed = 1

Total PV Array = 14 Panels
