Hi I am looking for suggestions and tips with my conduit run as I will be moving my arrays to their permanent home and wiring.
My runs are going to be ~125 underground, then another +/- ~100' along the base of the house (under the deck etc).
From past recommendations we have settled on running 10 awg THHN from the DC solar disconnect to the inverters. I plan to pull wire for (2) arrays right now (4 x 10 awg) and plan to add another 2 arrays down the road for a total of 10 awg wires.
Questions: Do I need to run a ground back from the panel frames or simply ground those to a rod at the arrays?
What size conduit would be recommended that take the initial fill ( 4 x 10 awg) and allow for an easy pull of another 4 in a year or so?
I don't want to go to big and waste money, but I don't want to add more conduit later either.
All tips and suggestions appreciated.
BTW - How do you lay out a ground mount to face true south? I have a compass and know the declination but am at a loss on how to calculate the post locations.
