Replying to the original @ashthekid post: I had my power supply upgraded to 3-phase for future fast EV charging as part of a whole house renovation, which included installing electric cabling from my loft to basement consumer unit for a future solar installation. I signed up for a 3.2kWh SolarEdge optimised PV system with Green Energy Together as part of a local council scheme, which was finally installed recently (GET is a topic for another thread…). However, my contractor had only run a single-phase 3-core cable, hence GET could only install a single-phase SolarEdge 2.2kW inverter which is connected to the L1 phase of my power supply (running a new 3-phase 5-core cable internally from the loft to the basement consumer unit would have been very disruptive). My house circuits are distributed randomly across all 3 phases, although L1 has some key circuits such as kitchen appliances and boiler. I currently have no 3-phase appliances, although intend to install either a single-phase 7kW or 3-phase 22kW Zappi charger as I have an EV on order. I was previously told that having the PV system on only 1 phase wouldn't balance over the other phases, however as @joth has mentioned 3-phase meters should employ net metering (my meter is a "dumb" Landis Gyr E230 and I am on British Gas's waiting list for a smart meter). My average daily consumption is around 16kWh, so will unlikely I will be exporting much, if at all. Having considered downgrading my 3-phase supply to single-phase (which apparently involves capping 2 of the phases and installing a new single-phase meter), I've decided that it would be simpler to keep the 3-phase supply for future proofing, and perhaps rewire my consumer unit so that more base load circuits (including the future EV charger) are connected to L1 phase. Any thoughts on this would be welcome.
