Ended up going to neighbor's house to help him with wrapping up his solar project. Finalized the wiring in the shipping container that is his mech room... we have a 50amp feeder from his meter base to the mech room that's fed from utility for emergency use, and we have a 100amp feeder going back to his house. Modified his panel box today to have a transfer switch, took about 30-45 minutes to install some new 4/0 alumumim SE rated cable... that stuff is stiff. So now his house has a transfer swtich to go between solar inverter power and utility grid. Carried his four 16kwh batteries out to the mech room and got his inverters powered on. They are not programmed to be split phase YET but they did power on and make 120v each. While I was finalizing the wiring inside the mech room, he was pulling 10AWG THHN in conduits going to 6 columns of solar panels. Each column is 4 panels in series on one face of his roof and 4 panels in series on the other face of the roof. Those panels are combined to make a 4s2p set of panels an there are 6 sets of these. He's getting the wires into the mech room tonight.
