I have a pair of Growatt SPF 3000TL LVM-ES inverters in split phase. Is it possible to add a third inverter to just one leg of the split phase? I just want to know if it will work at all, I already know I will have to do some creative wiring with breakers to make is safe. I know that one leg at 3000w and the other at 6000w is not normal and not balanced, but I have a need but don't want to have 4 inverters if I don't have to (wall space is an issue, plus cost).
