Solar Hybrid PCU Sine Wave Inverter

RD SOALR UPS is an integrated 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. Battery Voltage, 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.

Salient Features*
