It’s in use in Japan as i understand it but in the UK the DNOs currently don’t have appropriate controls in place for when the power goes out as i understand it. I believe people with solar and batteries on their property have no power when there’s a power cut - their inverter turns off for safety of the DNO operatives if mains power goes out.
Im not that clued up on this. Tent with a big pinch of salt…!
Oh I see! Right, yes, that applies to my two inverters, which have an "off grid" mode which I don't use for this reason.
The electrician who wired in the system offered to add in an isolator to cut the house off from the mains. That way I could use the "off grid" mode, but it'd have to be something pretty bad for me to want to use it & reconfigure the inverters too.
