Growatt SPF 3000TL LVM-ES Split Phase with 3 Inverters

[maximus57]

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).

I believe it's an option in the manual.
But I don't remember for sure.

The manual does not show an odd number for split phase, but I wasn't looking at the 3 phase options, which do show odd setups. So now that I looked at the 3 phase options shown I guess I can assume it will also work for split phase, and it gives me a good idea of how the cables need to be hooked up. Thanks for pointing me back to the manual.

Check the growatt website, I think you can pair it to a single growatt with the black-red wire+db9 cable chain correctly, but Im sure there is info in the online manual
