Is it possible to install a MultiPlus-II 48/3000/35-32 combined with a single phase PV and Battery on only one phase of a 3-phase-grid house system? Target: Reduce cost compared to a 3-phase-system, but still have a backup in case of grid power loss. All the critical loads in the house are connected to that one phase. There are no specific 3-phase-loads in the house used.
I ask, since so far I've not seen in any description duch a system design...Thanks for any advice!
