Working Principle
Advanced solar pumping inverters convert DC
voltage from the solar array into AC voltage to
drive submersible pumps directly without the need
for batteries or other energy storage devices.
The system consists of solar
array, solar pump inverter,
pump, storage tank and other
components.
