@Welshman that inverter use 360v to 500v batteries, not 48v, you'd have to use the specific Growatt batteries.
@Mercenary Keyboard Warrior Don't forget power is often distributed on 3 phases, so a third of the houses are on each phase. Not sure if this applies for every where though. This is one very good reason why you shouldn't connect power between different properties, they could be on different phases and that means 415v, 240v is one phase and neutral.
I hadn't even considered phases. I think my curiosity is getting a little bit beyond being easily sated. I think I will give up
