@matstace 1 phase, eh?

@skolima Indeed. The “big boy" wall charger is booked for the 30th April, but that's still only single phase, so overnight trickle charging (after this initial charge) it will be.

@matstace I mean, I've just got a 22 kW charger installed (and have the grid connection to support it), but, in reality... it's trickling 4-5 kW from the photovoltaics spare production, not going full speed.

Unless it's winter and I'm using grid electricity to charge, well, then it's full speed ahead captain!

@skolima Apart from today, because day one, and the car needed a charge after buying it and driving it home (dealers are the same with petrol and electrons - almost empty), I'll be charging overnight, never from solar.

Because overnight = 7p/kWh, and solar export = either 12.74p or 25.33p/kWh, so it makes no sense to keep those electrons for myself.

@matstace So... your solar export is priced higher than I'd buy electricity for. WUT?

@skolima Octopus have updated their tariff today, so the sums have all changed again. Still just about worth charging overnight though, to make sure the battery is full before 4pm for the juicy peak export rate.
Because I inherited an old feed-in tariff from the previous owners, I also get 20p/kWh generated, whether I use or export it, which definitely helps matters :-D

@matstace oooh

Are you eligible to keep that if you expand the installation?

@skolima Sadly not - I already gave up the export part of the feed in tariff to switch to the smart export (although with the new prices, that is getting close to being a mistake), but if I change the installation in any way (eg swap the panels for ones with micro-inverters, or add panels) then the feed in tariff goes away and I have to switch to whatever the current offering is (which is very much not 20p/kWh generated)
