Hello!Is there some other way than buying 3x Multiplus II for my Solaredge 3-phase inverter, to have backup (ups and working pv) for off-grid scenario? Can it be done somehow to have only 1-phase backup?

As far as I know, if the solaredge loses a phase it will shutdown. So no, you will need to get 3x Multiplus-II to generate 3-phase so the solaredge will continue to run.
