World's leading solar pumping system professional manufacturer
PB-G2 series solar pumping inverter
Solartech PB-G2 Series Solar Pumping Inverter controls and regulates the operation of solar pumping system. It drives the pump by converting DC power produced by solar array into AC power and adjusts the output
frequency according to solar radiation in real time to implement maximum power point tracking (MPPT).
