Got a customer with large victorian house split into flats, including his own. Now he is keen to have PV installed, and has big enough roof to take more than 4 kW. What I can't quite think is how we could arrange a 3 phase output when there are so many meters. Obviously the owner has single phase supply, and the 6 flats have their own key meters split across the phases. It's not unfeasible to break into the tails, but I'm concerned about Fit applications, and a mismatch of metering in general! Anyone come across this situation before?
