V2L function to power the house?

2 - Use the V2L output to power a DC power supply. Then feed this into an approved grid-tie inverter (when specs emerge such devices appear).
Setting the GTI to run during the day, and the car to charge during cheap off peak rates.
This would allow you to load shift using the car's battery.

However... both would require a lot a lot of charging lead/V2L swapping, or hacking your charger about. And DIY engineering.

This is pretty much what I have installed BUT I disagree (nothing new there!) that it "would require a lot a lot of charging lead/V2L swapping, or hacking your charger about" I have a DIY battery system and inverter installed at my house. I use an ex server power supply that has adjustable output connected to my batteries. On the initial setup I waited for my house batteries to get down to 75% and adjusted the power supply to take 3kW from our MG5. The real beauty of this system is that it can be used any time not just in power cuts, to adds a useful 50 kWh of storage to my existing 30 kWh, it's simple to connect up, a lead from the battery enclosure to the MG5 is all that's needed, switch on and enjoy. If the demand on the inverter is less than 3 kW, the batteries will start to charge at a very slow rate, as the voltage increases during charging, the current from the power supply drops off. If I leave my inverter with no load the batteries get to around 87% and the supply from the MG5 drops to 30W. Later in the day as more loads co0me on the current from the power supply increases up to it's 3 kW maximum.
It does of course rely on having a Grid Tied Inverter, batteries and a power supply. I had all of that so the cost was minimal to install it.

Sorry Bam Bam, I have to take exception to this, what I do IS safe, it presents no danger to people or equipment.

Apologies for my misunderstanding. I remembered some debate about something, but I couldn't remember what. Will edit the post.
