Solar code is note something I work with very much, but I have a question/scenario that I am dealing with. Sol-Ark 5k inverter with 2 Solar strings attached. Critical loads panel, (2) Fortress 5.4kw batteries, and generator. Wire size from inverter to back fed 30 amp breaker is #6 thhn, wire size from load breaker in inverter to critical loads panel is #6 thhe, wire from 50 amp generator breaker in inverter to generator 50 amp plug is #8thhn. Both grid breaker and load breaker in inverter are 63 amp I believe. Can I increase the back fed breaker in the main panel from a 30 to a 60?
My concern is charging of the batteries when solar production is limited, along with loads that are moving to the critical loads panel.
