I have an existing solar system with panels on a shed roof and back wall. It produces way more power than I can use at the shed, so I'm going to rewire the panels to a new system that will be in the garage (EG4 12000XP, 20KWH battery). The DC run from the shed-to-inverter is about 210 feet. I got this guidance from the author of a YouTube channel I follow:
"Metal Conduit is required on DC power from Solar panels when it is on or inside a building until it gets to the first disconnecting means. (which is usually the disconnect on the inverter). DC power when not on or in a building can be run in PCV. AC power is run the same as any other residential installation." I really like this guys videos.
Wires from the panels go through the shed roof, enter a short run of PVC conduit (in the shed), then to a DC breaker that I use as a disconnect for the panels. From the DC breaker, the wires, still in PVC conduit, go to a wiring trough, and then to the 3K inverter.
The DC breaker is the first disconnect. As I read it, I can use PVC from the DC breaker to the garage inverter. The run will go underground, then up to an attic, then over to the connected garage, and then down to the inverter; all using PVC. Sound OK, or does metal conduit have to be used somewhere?
