Battery Charging
Intelligent battery charging -3 Stage(Bulk,Absorption&Float) Charging for enhanced battery life
Solar Priority Mode
Under this mode, solar power is used to charge the batteries to full when available and once the battery becomes full, the site load is shifted to the battery and solar till a predefined battery voltage level thereby solar energy is utilized full.
Grid Priority Mode
Under this mode, batteries are charged from grid as well as from solar, Loads are normally powered by grid when available. Under grid failure, loads are supported by solar. This mode is suitable for non sunny days.
Warranty
2 year
