VEICHI SI-30

VEICHI SI-23

Solar pumping systems convert solar energy directly into electric energy, which is then used to power motors that drive water pumps that extract water from deep wells, rivers, lakes, and other water sources. Solar panels, a solar pump inverter, and a water pump make up the system.

Solar pump inverter, also called solar variable frequency drive, converts the direct current of solar panel into alternating current, thereby driving various AC motor water pumps (centrifugal pump, irrigation pump, deep well water pump, swimming pool pump, etc.), the input can be the solar DC power supply (DC60-450VDC；DC 150V-450V, DC 250V-780V), also can be single phase or three phase AC power supply (AC110VAC，AC 220V, 380V, 460VAC), built-in MPPT control system to maximize the output power of the PV array, is very suitable for use in remote and dry areas. Details of VEICHI models are mentioned below.
