@skolima I’ve got a 5.5kW PV array, but at the time capped it with a 3.5kW inverter because I didn’t want to bother applying for permission for a larger export.
My next project is battery storage, and I’m considering fixing the inverter and the export at the same time.
@katiefenn I really want more battery. It would add a reasonable number of no grid days even with the heat pump @skolima
@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.
@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).
