Today, I wired up the Enphase trunk cable on the roof of the garage to 12 ga wiring fished through the 3/4″ PVC conduit and junction boxes. I also installed the MidNite Solar AC Combiner and Disconnect Box. My utility requires an AC Disconnect, which is always accessible (required to be on the outside of the building.) It also must be lockable in the off position and have specific wording on it.
The MidNite Solar box has two 20 amp breakers in it, one for each of the two rooftop circuits. Those two circuits are then combined and travel over 10 ga wiring inside the garage to a 30A breaker.
