Solar PCU is an integrated 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. 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.

Maximum battery charging is done through the solar to reduce the energy used from grid power. PWM and microcontroller based pure sinewave 48V-3.5KVA hybrid solar inverter cum PCU with PF of upto 0.80 which is mostly used for running AC loads of upto 2800W which includes all types of lighting, home loads and even water pumps of upto 1HP however only 5 star inverter type air conditioners can be run.
