Hi,
We installed a decent size (39kw) residential array using micro-inverters. We used weatherheads going into the back of the AC combiner panel. I thought it was a clean installation but the inspector said the weatherheads aren't UL listed for the application. I was wondering if someone could help me with some UL document that would show it is okay- I am assuming it is okay. The PV wire conductors are probably 6.5ft above grade under the array. See the attached picture.
He also called me on not having a neutral in the panel. I know this is okay to not have a neutral in a panel but if I remember correctly the panel needs to be labeled "240V panel No Nuetral" or something along those lines. Any help with code references for this would be greatly appreciated.
Thanks ahead of time.
