A Solar On-Grid inverter converts the DC output of PV modules into AC power suitable for transmission on the owner grid or uses it for your own consumption, often deploying reactive power to meet new grid codes. It must always optimize the power output via MPPT (maximum power point tracking) and additionally monitor both the system and grid connection. In practice, each solar inverter installed in solar power plants needs to connect an array or string of PV modules to the power grid. It’s more efficient the inverter, the better the LCOE (Liveliest Cost of Electricity) generated by the system.

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/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 to the Grid/DG power and also charge the Batteries through the in-built Grid Charger. 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 & continue to charge the battery bank from the available Solar power.
