Model No: SG320-2S Series

SG320 220V 1Phase Utility Model MPPT Solar Controller

The SG320 series inverter is a low voltage AC drive of 0.3 to 400KW above rating designed to operate with energy drawn from solar panel or photovoltaic cells (PV). The inverter is customized to operate in dual supply mode, so the grid connected supply is used in the absence of energy from PV cells. This inverters functions with the latest in technology maximum power point tracking (MPPT) algorithm to derive maximum power from the PV cells at any instant.
