@bloor@bloor.tw @damien@layer8.space it may be worth looking at putting certain circuits on a board fed by a changeover switch with one feed from the mains and another from an external socket which you could connect a car with v2l

@nick @damien That's a good idea. But in the medium term (next year) I'm going to do something a big bigger I think. My plan currently involves 25mm2 SWA from my utility head/henley blocks (via an isolator) to my garage, where it will feed the grid input of a Victron Quattro 15K. Then the inverter output of the Quattro will come back to the consumer unit in the house via another 25mm SWA. Garage CU fed direct from the Quattro too. The Quattro will have a Fogstar 32kWh 48V LifePo pack on it.

@nick @damien == 15kW "whole house UPS", ability to buy power and charge up on cheap rates. And use from the battery. And then finally, I think I can squeeze 16-20kWp of solar on my roof, to hopefully make it so I pretty much hardly have to buy power off the grid. At least, I think this will be doable about 3/4 of the year, ish.

No export. No hassle with G99/G98 etc.

The Quattro has a 2nd power input, and I'll attach that to the V2L of my car, for extra offgrid capacity.

@bloor @nick @damien Nice! No solar here, so I have two live feeds from sockets on different circuits going to an automatic transfer switch, with the output feeding a 3kW UPS.
