Powerwall on-grid (UK)

Does anyone know if you can have the Powerwall 2 installed on-grid (so that you can charge it off the grid, but later install solar off-grid and only supply power to the Powerwall from solar PV?

Basically a self installed solar PV system works out very cheap, but if you have to have a certified system installed it almost doubles the cost, and I wouldn't get much feeding the grid anyway. All I'd want is to be able to then connect my off-grid Solar PV array just to the Powerwall and store the generation.

Is that possible?


  • I'm about 95% sure it is ok in the UK. It's not in the USA. Hopefully, a UK owner can pipe in.
