    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, Prosine 1800 and Exeltech 1100, ForkLift battery. Off grid for @13 of last 14 years. 1000 watts being added to current CC, @2700 watts to be added with an additional CC.
