    I thing 6 or 8 gauge s usually called for, 6 gauge bare ground wire is reasonably cheap and can often be bought by the foot.
    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.

    And how many 10 g pv wires am I aloud in 1” conduit
