Solar Water Pumping system
Testing Kit
Experiments to be performed
Power & Energy measurement (PV & INV)
Connect the clamp-on ammeter to the power cable that runs from the inverter to the water pump.
Connect the voltage meter to the power cable that runs from the inverter to the water pump
Turn on the water pump and record the current and voltage readings.
Multiply the current and voltage readings to calculate the power consumption of the water pump.
To find energy
energy reading
Frequency Measurement
LPD capacity testing
A power analyzer
Maximum power
Connect the power analyzer to the input of the solar water pumping system.
Connect the load resistor to the output of the solar water pumping system.
Connect the water flow meter and pressure gauge to the discharge side of the pump.
Turn on the solar water pumping system and gradually increase the load on the system until the system reaches its maximum power output.
Record the power, flow rate, and pressure readings.
A load resistor
A water flow meter
A pressure gauge
Suction, Pumping & delivery testing
Vaccum reading
Connect the vacuum gauge to the suction side of the pump.
Turn on the pump and record the vacuum reading.
The vacuum reading should be within the manufacturer's specifications. If it is not, then there may be a problem with the pump or with the suction line.

Procedure
Connect the torque wrench to the pump's shaft.
Connect the tachometer to the pump's shaft.
Connect the thermometer to the pump's inlet and outlet pipes.
Connect the flow meter to the pump's discharge pipe.
Connect the pressure gauge to the pump's discharge pipe.
Turn on the pump and allow it to reach a steady state operating condition.
Record the following readings:
Power (kW)
Torque (Nm)
Inlet temperature (°C)
Outlet temperature (°C)
Flow rate (m³/h)
Discharge pressure (bar)
Connect the power analyzer to the pump's input power terminals.
HP = (Power * 1.34) / Torque
