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 charger the battery bank either through Solar or Grid/DG set.

The PCU continuously monitors the state of Battery Voltage, Solar Power output and the loads. Due to sustained usage of power, when the Battery voltage falls below a preset level, the PCU will automatically transfer the load, the Grid/DG power and also charge.

Once the Batteries are charged to the preset level, the PCU cuts off the Grid/DG Power from the system and will restore to feeding the loads from the battery bank & also restore to charging the battery from the Available Solar power. The PCU always gives preference to the Solar Power and will use Grid/DG power only when the Solar Power/ Battery charger is insufficient to meet the load requirement.
