Which Tesla batteries are compatible?

You can join Amber for Batteries using Amber’s SmartShift™ technology with a Tesla Powerwall 2 only.

How do I sign up to Amber for Batteries?

If you haven't already provided the battery details during sign-up for your Amber account, follow these steps via the Amber app:

1. Download the Amber app.
2. Log into the Amber app using the email and password created on registration.
3. Head to the Devices tab at the bottom of the screen.
4. Select Tesla as your battery brand.
5. Fill in your battery details in the form.

What happens after I sign up?

We've published this guide on the Amber for Batteries Enrolment Process if you want to take a deep-dive.

After you've signed up to Amber and submitted your battery details via the website or app, we will check that your site is all set up to join the SmartShift™ program. This includes making sure that you've officially transferred to Amber as your electricity retailer, that you've got a smart meter installed and that your meter is configured to record solar exports. All this has to happen before we can continue with the battery enrolment.

Once your site is good to go, our Operations team will request access to the battery control from Tesla. The Tesla team then processes enrolments once per week (usually at the start of the week). They will let the Amber Operations team know if there are any issues with the enrolment. Please see the below for common issues that may delay the enrolment of your battery.

Checklist to avoid delays during enrolment

Did you use the correct battery details during sign-up?

• Please ensure you're using your Tesla Gateway serial number (and not the actual battery's serial number). 

• This can be found on the “My Home Info” page of the Tesla App and should look like this example: STG2181440089Y1.

  1. Open the Tesla App on your mobile, and go to your Powerwall product page, and then click “Settings”

  2. In the Settings page, click “My Home Info”

  3. The Gateway serial number is shown below “Powerwall Gateway”. Long press the serial number to copy it to the mobile phone’s clipboard.

Did you unenroll from your previous battery optimisation program?

What to do if you're in a virtual power plant (VPP) before you join Amber (+ clues to tell if you're part of a VPP if you're unsure)

Remember how we ask you during sign-up if you’re already enrolled with another VPP? Well, if you end up still being with your previous provider when we try to enrol your battery, Tesla will let our Operations team know and we will send you an email requesting for you to get in touch with the previous provider.

Tesla will re-attempt the enrolment to Amber for Batteries every week so when your previous VPP has unenrolled you, Tesla will automatically enrol you to Amber for Batteries from their end and we can then continue the onboarding journey. However, this is somewhat dependent on when you request that your previous retailer unenrols you from their VPP and when they complete this request.

What if I have multiple Tesla batteries?

We may not need to onboard your batteries separately as this depends on how the batteries are configured at your site.

Please check if both Powerwalls are registered under the same Gateway ID. This is usually the case if you have one phase for exporting power so Tesla will combine both devices under one ID. If this is the case, we don't need the additional battery number as both will be combined anyway.

You can also usually check whether there is one or multiple Tesla Gateway IDs in your Tesla app home screen.

Should you have multiple phases and both batteries have their own Gateway ID, please follow these steps to enrol the additional device(s).

1. Open the Amber app.
2. Tap 'Devices' and navigate to the 'Plan' section
3. Scroll to the bottom of the screen, then tap 'SmartShift™ Settings'.
4. Tap 'Add another device', then provide device details in the form.

Getting your Tesla system ready for automation

Remove time-based control settings

For Amber for Batteries to work optimally, your Tesla Powerwall settings must be set to ‘Self-Powered’ as the Operational Mode. You can check/change this as follows:

Step 1: From the home screen, open the ‘Settings’ menu.
Step 2: Open the ‘Powerwall’ menu.
Step 3: Under ‘Operational Mode,’ select ‘Self-Powered’.

If not set to ‘Self-Powered’ the Tesla settings could override the SmartShift™ controls.
