This 12V 650VA hybrid solar system consisting of a Solar Charge Controller, Inverter and an AC Mains Charger. Batteries are charged either through Solar / Grid / DG set or with sharing of current. System gives priority to Solar Power first and uses Grid power only when Solar Power / Battery Charge is insufficient to meet the load requirements. Solar Power output and the load are continuously monitored. Solar Power output and the load are continuously monitored. When batteries are charged to preset level, the Solar UPS automatically cuts off from the system and load runs through the UPS using the batteries
