- TESLA across the front.
- The on/off switch and the status light are on the right-hand side.
- The rating label is under the clip-on side cover and reads POWERWALL 2 AC.
- Its part number starts 1092170, 2012170 or 3012170.
- No solar inputs. Tesla says not to connect it straight to solar panel wiring.
Next to it in the drawing stands a Powerwall 3, 609 mm wide.
Tesla's 2016 annual report says production and deliveries began in the fourth quarter of 2016. The same report calls it a 14 kWh battery, while the UK datasheet gives 13.5 kWh as usable. We go by the datasheet.
Tesla's UK page of December 2016 said UK installations would begin in February 2017, and gave its depth of discharge as 100%.
What a Powerwall 2 works with
| Unit | Works with a Powerwall 2? | Notes |
|---|---|---|
| Powerwall 3 Expansion | No | Powerwall 3 only. |
| Powerwall 3 | No | Tesla says a Powerwall 3 can't be added to a Powerwall 2. |
Put every Powerwall 2 you're selling on one form, and one written offer covers them all.
The Backup Gateway
We buy the Powerwall 2 units themselves, but we don't buy the Backup Gateway. It still helps to mention one in your notes, so our engineer knows what's on the wall before the day.
Moving a 114 kg battery
On a ground-floor wall with a clear run to the drive, a Powerwall 2 is a straightforward lift. Up steps or along a tight side passage, it takes more planning, and a picture of the route in from the road helps.
Tesla's UK datasheet lets it stand on the floor or hang on a wall. One standing on the floor is the easier of the two, because nothing has to come down from height.
A Powerwall 2 that's already off its wall can go to our Bradford and London bases, which take drop-offs by appointment.
Whichever way it reaches us, send us the app screenshots first, then remove each Powerwall 2 from your Tesla account.
Powerwall 2 units on the form
"Powerwall 2" is already chosen, so start with how many you're selling.
The label we ask you to photograph is under the Powerwall 2's clip-on side cover, and Tesla's owner's manual shows how that cover comes off.
What's a used Tesla Powerwall 2 worth?
We don't publish a price list. Each Powerwall 2 gets a written offer of its own, worked out from how hard it has worked by the Tesla app's own figures, and from where it is fitted. Send the app screenshots with the form if you have them.
Before we collect
- Before we collect a Powerwall, we ask for screenshots from your Tesla app and a photo of the label on each unit.
- The screenshots we need are the app's home screen with any message showing, 'Settings' then 'My Home', and the Powerwall graph under 'Energy' for a recent day and for 'Lifetime'.
- They show us what's fitted, how it has been used and whether the app is showing an alert.
- If the screenshots, or the kit on the day, differ from your description, we may send you a new offer, or withdraw ours, and you're free to walk away at no cost.
Please don't take it off the wall yourself
A Tesla Powerwall's DC system runs at up to 450 V DC inside, and it's wired into your mains supply. A Powerwall 3 also takes solar panel strings at up to 550 V DC. Switching it off doesn't make the battery safe, so our engineer isolates the system before anything is moved. If your installer has already disconnected it, say so on the form.

Questions about the Powerwall 2
Is my Powerwall a Powerwall 2?
Measure it, and look at the sides. A Powerwall 2 stands 1,150 mm tall and 753 mm wide, with TESLA across the front and its on/off switch and status light on the right-hand side. The label under the clip-on side cover reads POWERWALL 2 AC, with a part number starting 1092170, 2012170 or 3012170.
Will my solar panels keep working if I sell my Powerwall 2?
A Powerwall 2 has no solar inputs. Tesla says not to connect it straight to solar panel wiring, so your panels run through their own inverter.
How do you take a 114 kg Powerwall 2 off the wall?
First our engineer makes the whole system safe, then disconnects the Powerwall 2. Tesla's UK datasheet says a Powerwall 2 made before March 2019 differs slightly in size and weight, and its UK page in September 2017 gave 755 mm wide, 155 mm deep and 125 kg. If stairs, a narrow door or anything else stands between it and the van, say so on the form, so the lift is planned before the day.
