I have a very specific system in mind. I want to replace a tri-phase 240v connection to the house because it is 3 times as expensive as single phase power and have a backup power source. But there is an issue, there is a 2 phase 9kVA appliance in the house that is used sometimes. The 9kVA appliance is in two of the phases, and the whole house is in the other. My options are to move the house into the two phases provided by the victron and let them manage the incoming single phase grid somehow (which I think is not possible), or have two victrons run the 9kVA in an off grid type bi-phase system when grid power is functional, and switch one of them or the two of them when the grid goes down to power the house which would be in another circuit.
