Buying a cheap EV with 50kwh of capacity seems like a good option?10kw pack is about £4k, so £12k ISH.

The sums are easy kWh, not kW see...I like the sound of this idea, but "Confused from Northampton" (me) wants to know -
How long does the 30kw battery (of what voltage?) run consumables for ?
I assume theres a controller (& inverter?) involved (?)
And also, for simplicity, assuming there's a 240 volt constant draw of 1kw
I need an "Electrickery for Dummies" type explanation
I would add, my daily electric consumption is around 24kw...
If your paying to have it fitted, if batteries are bought with the solar array for domestic its vat free, if batteries bough after the solar and fitted later you pay the vat!10kw pack is about £4k, so £12k ISH. Usually cheaper with solar PV if done as a bundle. Modern controllers will permit island mode if there is a power cut
I was told that had changed recently and retrofit batteries were also VAT free.If your paying to have it fitted, if batteries are bought with the solar array for domestic its vat free, if batteries bough after the solar and fitted later you pay the vat!
I was just thinking use the VTL to power the house...I think a cheap MG4 has 54kwh battery and the onboard inverter can supply 7kw at 240v (I think!). It doesn't support proper VTH so would have to be manual switching.Not really, you will need the controller, a cooling system probably a lot of hackery to make it work and not have any support should it not work
VTL is vehicle to load...its only 1 way so not the same as a proper house battery system like @Kayos is describing so it's apples vs oranges....Google and I are confused as to what VTL stands for.
Visual Programming Language?VPL?....oh wait a minute
Some Off-Grid Inverter Chargers are programmable & have a pass-through relay to allow seamless switching from AC supply (either Grid or Generator, some have inputs for both) to/from battery bank.I'm planning to do this when we move house...I have an EV but I doubt it's a requirement.
Octopus as I recall do Tariffs with and without the dedicated EV charger.
Quite a few folk doing it with a manual switch over which isolates them from the grid (safest option for dummies)
you can only reduce by so much even my 220.00 for 3 months isnt its true rating7kW from a BEV seems high to me. Mine only supplies a maximum of 3.6kW. I’m not suggesting an untruth - but that it needs checking out.
Upshot of this lot is that low power usage is not very viable for most. Solar generation, sold to the electric supplier, can be effective but I’ve not seriously considered it so far.
Reducing consumption is, by far, the best way to reduce energy bills. Solar generation is good, from the point of climate change, and is generally a good way to go - after pay-back, the reduced energy costs can be considerable and panels are often good for decades.
