Solar water pump is through the photovoltaic water inverter using the photovoltaic array of power to drive the water pump work photovoltaic water pumping system, the system is mainly composed of photovoltaic array, photovoltaic water pumping inverter, photovoltaic water pump. It is mainly to convert the sun’s light energy into electric energy to provide working power for the load pump motor.

The photovoltaic water lifting inverter or controller can control and adjust the operation of the solar water pump, drive the water pump with the electric energy emitted by the solar array, and adjust the output frequency in real time according to the change of sunshine intensity, so that the output power is close to the maximum power of the solar battery array. Pump, usually lift liquid, transport liquid or make liquid increase pressure, that is, the prime mover mechanical energy into liquid energy so as to achieve the purpose of pumping liquid machine collectively referred to as pump.

A pump is a machine that transports or pressurizes liquid. It will be the prime mover mechanical energy or other parts of the energy transfer to the liquid, so that the liquid energy increase, mainly used to transport liquids including water, oil, acid lye, emulsion, suspension emulsion and liquid metal, can also transport liquid, gas mixture and liquid containing suspended solids. The technical parameters to measure the performance of the pump are flow, suction, head, shaft power, water power, efficiency, etc.

According to different working, principles can be divided into positive displacement pump, vane pump and other types. Positive displacement pump is the use of its studio volume changes to transfer energy; Vane pump is the use of rotary blade and water interaction to transfer energy, there are centrifugal pump, axial flow pump and mixed flow pump and other types. According to the control principle, centrifugal pumps can be divided into AC pumps, brushless DC pumps, brushless DC motor pumps, brushless DC magnetic isolation pumps, three-phase AC pumps, etc.
