I’ve literally just had 6.5kw of panels, a solis inverter and 10kw of puredrive batteries installed. If you’ve got any burning questions I’ll do my best to answer them.

I’m reference to your actual question, when you say a “self heating battery”, is that the same as a “solar battery” - which to all intents and purposes is a hot water tank with an immersion heater in.

We already have a hot water tank with 2 immersion heaters, so I bought a box called a Solic - which basically takes any excess solar that you would otherwise be exporting to the grid, and instead diverts it to the immersion heater, giving you free hot water. So it basically turns our hot water tank into a “solar battery”, for £200. It certainly works, water has been noticeably more plentiful and red hot since installing!
