the gslc attached to gs8048 accepts max 1/0 wire but 200 amp service panel needs 2/0 copper for code and afraid to backfeed this panel since i read something in the 2017 nec that you cant back feed if it is line or load...if i can, then is the 200 amp breaker useless and just cap off?? doing split phase.....from my ground mount (280v and about 35 max amps from 3 strings) I bought #1 cu wire for l1,l2,neurtal and #6 ground to go from inverter to main.
