I picked up the wire last week. Decided to get in there and remove the wiring from the old unit I had in here. The wires runs on top of a steel beam behind my sliding doors which separates storage from tanks. That unit had dual outputs so 4 sets of #12. Guess what I found when all those wires removed? My 6/3 land line cable. Teton ran them to there, across and back to breaker box. Sweet. Made this easy. Went ahead and mounted a new inboard surge protector. Made wiring easier. Got inverters wired and tie in ready to be made. Got rather warm today and didn't want to shut down air conditioner this evening. Do that in the morning while cool.
