I briefly charged my car this morning which drained my solar battery of 1.8kWh. I usually set the solar battery to HOLD when I charge the car but this time I didn’t.

The Charge app now says I used 1.8kWh and for that power I will be charged 24p instead of 49p so I’ll have 25p credit on my next bill. (I’m on the standard OVO14p/kWh tariff)

Interestingly, like everyone, my bills are based on my meter readings and the 1.8kWh won't have “passed through” my meter since it didn’t come from the grid supply. (at least that’s what I assume to be the case). So, that implies that OVO will be giving me 25p for the 1.8kWh I used from my solar battery. Essentially, it seems, OVO will be giving me 14p/kWh every time I charge my car from the solar battery.

This all sounds too good to be true so it probably isn’t! - can anyone see where my thought process is wrong?

Solved - after a few hours my total credit for the month has dropped by 25p (although there’s still the extra credit shown for today).

I guess OVO eventually looks at the regular smart meter readings and says “wait minute I don’t see the 1.8kWh on the meter so I’ll take that credit back, thank you very much”.

Presumably you’re using managed mode with your charger? 

If so, and everything is connected correctly, it should see and cater for any solar usage

Yes it’s a managed charge. All is well and OVO aren’t donating money for my solar power sadly!
