Solar Photovoltaic Panels are used to convert Solar energy into electrical energy. These Solar PV panels produce DC power. PCU operates in parallel with the grid utility. This DC power is then used to charge the batteries through charge controller. Additional energy will be exported to the grid via the same bi-directional PCU system. Whenever grid voltage and frequency goes beyond the operating range, the same will be disconnected from the grid. PCU will supply the continuous power to load without any interruptions. Bhaskar GCI is single phase output, bi-directional inverter system. Solar Photovoltaic Panels are used to convert Solar energy into electrical energy. These Solar PV panels produce DC power, which become input for the inverter. The inverter converts it into conventional AC power. This AC power feed to the supply grid.
