Yeah but I’d rather avoid a situation where discovery of my unsanctioned solution for dealing with potential temporary power cuts leads to my supply being cut off “for safety reasons”.
I'm talking about something like this
Automatic grid disconnect switch:
Once it's got EU safety certs there's nothing unsafe about it,
It automatically switches depending on mains status.
If mains fails it switches to battery and disconnects from grid. And then reverts automatically.
Fuck their legalities, it's completely safe and no one would know
