3700W Solar Pumping Inverter with MPPT high efficiency Solar PV Water Pumping System Sandi PV pump system is different from traditional AC pump application system, PV pump system is using solar cells to directly convert solar energy into electrical energy, then PV pump inverter drive the AC motor to drive pump getting water from deep well, river, lake etc., finally transport to the destination to meet our demand for water. PV pumping system consists of four parts: PV array, PV pump inverter, three-phase AC pump and storage device. PV array absorb sunshine radiation energy and convert it into electrical energy, supply power for whole system. PV pump inverter is an important part of PV pump inverter system, which convert the output DC from PV array into AC for driving pump, and according to the changes of sunlight intensity in real time to adjust the output voltage and frequency to achieve max. power point tracking and max the use of solar energy. Product Description: Solar water pumping system is constructed with solar panel array, solar pump inverter and AC water pump, DC current produced from solar panel will be delivered to solar pump inverter, and it will convert it into AC current to drive water pump, and will automatically regulate output frequency according to sun radiance intensity, maximum realize MPPT tracking function.
