Is it possible to add a single phase PV Inverter on one Multiplus-II AC Out1 in a three phase ESS system, or does it have to be necessarily an three phase PV Inverter in this setup?
The PV Inverter Assistant states load must be symmetrical:
"Each phase must have the same Solar power installed". Is this really a must? I would like to add a small Fronius Primo onto one phase in a three Phase ESS
