Solar Power Conditioning Unit (PCU) is an integrated system consisting of a solar charge controller, inverter and a Grid charger. It provides the facility to charge the battery bank either through Solar or Grid. The PCU continuously monitors the state of Battery Voltage, Solar Power and output loads. Due to sustained usage of power, when the Battery Voltage falls below a certain level, the PCU will automatically transfer the load to the Grid power and also charge the Batteries. On Grid Solar PCU is a “Grid Interactive type Solar PCU” which is based on “Grid Tie & Off Grid” counterpart. This Model has the facility of using Net metering policy of our state by selling electricity to the Government. It works as a Bi-directional on Grid side which means power will be exported into the grid or power will be imported from the Grid.
