I have a roof plan with Hoymiles microinverters and I was planning to have two arrays on separate wiring. Each would need a 30 amp breaker.
I'm having a little trouble figuring out the combiner box. For permitting, do I need to have a UL listed box specifically for PV systems?
When I'm looking around online for a combiner box the prices seem all over the place. From $50 up to $700. I'm trying to understand what products I actually need.
Attached is the electrical diagrams I've drawn up with how I'm currently trying to lay it all out.
