Conductors, currents, and circuit protection – The AC side

In utility-interactive PV systems, the inverter becomes the source of current in the AC output circuit to the utility point of connection, and the utility resembles the load. The voltage on the AC output circuit of the inverter will be higher at the inverter terminals and will be lower than the voltage at the utility point of connection.

Addressing the Complexities of Load Side PV Connections

In past editions of the Code, the requirement was to use the rating of the PV inverter output circuit breaker to make subsequent busbar and conductor calculations. By allowing the use of 125% instead of the breaker rating, we get a slight advantage on the more complex systems since this number may be slightly smaller than the rating of the required circuit
