Here's another of the first batch of 90 Powerwalls to reach the UK, in my garage.

It is now set up to avoid discharging during my off-peak (=car charging) hours so it replaces more expensive day-rate power.
Will it ever pay for itself? I honestly don't care - it makes a difference to me, and that's what matters!
The Powerwall itself was £4500, but it was fitted to a new SolarEdge-controlled PV system so there were some SolarEdge components installed which I wouldn't have needed if I had not had the Powerwall. In other words, I could have got the same PV performance for less, using non-SolarEdge components.Congratulations! Hoping for a lot more posts like these... May I ask how much you paid?
Looks amazing!Here's another of the first batch of 90 Powerwalls to reach the UK, in my garage.

It'll be more - one of his tweets said something about a new charger as well. Assuming he didn't mistype, that opens up the possibility of a Tesla DC car charger. ie. it hooks into the 400V DC bus between the solar panels and the battery and inverter, and draws DC before it hits the inverter, and charges the car via DC (just like a Supercharger would). In theory, if you had a big solar array, you could charge your car faster than an 80 amp, or 20 kW HPWC.
DC charging would be a relatively small percentage of overall solar operation, so the inverter(s) would need to be sized for the total solar installation even if they aren't involved in the DC EV charging system.BTW, you DO NOT need a powerful inverter for this since you are taking solar panel DC and giving it to the car as DC. No inverter needed. Now you do have to match voltage, but the PowerWalls already do this for their internal batteries, so the extra parts count to allow the PowerWalls to modulate voltage for the Tesla car battery is minimal.
