@smallsolar @sheddi if you are paying a sparky price a proper install instead. A non fancy brand 3.6 or 5kW inverter that'll take standard 48v batteries is a grand, 16kWh of battery is about 1500 and some cables and stuff. Once you go over a tiny size wired in wins if you can do it, especially as the sparky can claim the vat off and you can't.

@etchedpixels@mastodon.social @smallsolar@techhub.social Sorry, thought I'd replied here but now see I didn't! I fully agree that for a larger system it makes sense to have a professional installation. I've already got a rooftop PV system (2012 vintage, relatively low efficiency but earning FIT money). My Ecoflow kit is a fun experiment that also fulfils an offer I made to my wife to make her art shed off-grid-capable (albeit only during the months she doesn't need heating).
