I have two quatros, one 8kw and one 5kw both connected to the same battery bank and supplying two separate mains phases on a boat. My question is can this be linked and controlled via one cerbo as a split phase or do the two units need to be identical?
Units in a 2 or 3-phase “linked” connection must always be of the same type … i.e. also of the same hardware version. Your two Quattros must therefore remain “lone wolves” …
