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.
