I've designed a system with a balanced three phase backfeed, three single phase 208v inverters loaded identically, combined, and then made to connect w/3 pole brk to a 208v three phase main panel.
Is there any reason why 2 larger inverters could not be used instead, and just land with a 2P breaker in the main? My understanding was that unbalanced loads are not favorable. Is this with regards to voltage only?
I know in some cases an unbalanced load can be favorable to rebalance, but assuming there was already a balanced panel, would it be unfavorable to backfeed with only A and B phase, and omit phase C?
