    @otfrom @skolima Same. We’ve only had a couple of days since mid-May that we’ve exceeded 10kWh total import, and that’s probably due to charging the car in off-peak hours. With a 10kWh battery we could have grid free days for all of it.

    @katiefenn @otfrom It's interesting how different registration is in different countries. Here in Poland for PV it's max(inverter, panels), and then for battery it's max(inverter, total battery capacity). If you have both it's the sum! That way I ended up registering both myself and my parents' houses for 40 kW grid connection each, 3 phase. At least up to that level it's a formality only, operator can't reject it and has to provide capacity.

    @skolima @otfrom (I forgot to mention that I only have one phase of electricity, and a plug-in hybrid car, so it only charges at 2kW max. But that’s plenty for us.

    @katiefenn @otfrom That's what gets me about UK electricity: single phase hook-ups. Over here even new flats have 3-phase (because you'll likely get an induction stove) and old ones can be converted (because every building has a 3-phase connection).
