V2L function to power the house?

the earth stake does nothing

I disagree.

The earthing rod connects the earth and neutral supply from the vehicle (or generator) to ground on the supply side of the RCD. If a human then touches a faulty device (i.e. one whose external metal casing has become live), some current will flow - via the human - to ground. The RCD will detect the resulting imbalance in current between live and neutral and cut the circuit.

I realise I'm late to this party, but it might be worth mentioning that I have that bog-standard cheapo VtL adaptor from eBay. I have run a 3 kw kettle from it many many times, and it boils just as quickly as it does when plugged into the mains. I have also run an 800 watt microwave which nominally draws 1.2 kw, and an induction hob rated at 2 kw. I also run smaller stuff like a pump for an airbed and the charger for my e-bike. I once accidentally ran both the kettle and the airbed pump at the same time.

I've mostly done this while out camping, but a couple of times I have run an extension lead into the house and run the kettle and the microwave from this. (One at a time, obviously.)

I haven't had any issues at all and everything seems fine. I'm currently having thoughts about maybe running the extension lead into the house to run a 2 kw electric heater during the day, on 3.5p/unit night-time electricity, given the price of fuel oil this month!

Obviously this has its limitations and is likely to constitute a trip hazard, but it's a hell of a lot better than nothing in a power cut. I think I could probably run the wifi router, my computer, a table lamp and the TV together, continuously (heating is otherwise catered for), and maybe unplug a couple of things to run the kettle or the microwave or the induction hob. I could also plug in the fridge and freezer overnight, I imagine, and if I only opened them momentarily during the day, stuff would probably stay fresh for the duration.

Same plan for me. No intention of trying to replace my electricity supplier except during a power cut and then only for minimal power.
