I am about to start my grid tied, permit approved solar panel installation on my roof. I want to buy wire, but I just realized I am not sure whether I am supposed to get solid or stranded THHN.
My design is PV wire to soladeck to 50 feet of 3/4" EMT to Solaredge 7.6kw inverter. I am planning 10 Awg (black, red, black, red) and 8awg green. This will be thhn through emt conduit. The DC will stay exterior to house.
Then from main electrical panel to AC disconnect to solaredge inverter, I am planning 40amp breaker and 8AWG thhn (red, black, white, green) through emt and liquid tight. This will be a transition from inside to outside.
Do I buy stranded wire for the DC and solid for the AC?
