On your inverter, you can add more panel capacity than your inverter rates. The voltage of the panels and the voltage range of your inverter determine how much more you can add on. The maximum output will still be restricted to the inverter rating. On almost all occasions, installing more PV than inverter capacity is a smart choice. Due to the solar functioning, a PV range with the same inverter capacity doesn’t use the inverter capability fully. Increasing your PV’s size improves the inverter capacity you paid for.
