Quick question. If you have a multiple inverter system being collected at a subpanel do you size the conductor based on the breaker size or inverter output currents?
For example, a 4 inverter system with max output current of 42A each would need a 50A breaker each at the collection panel with a 200A main breaker. However, the max combined current would be 4*42=168A. Which is value is the conductor size after the collection panel based on? And what is the code reference that defines this?
Thanks for the help!
