Tesla Powerwall 2 Recall: What Australian Homeowners Need to Know in 2025

Tesla has announced a recall of certain Powerwall 2 batteries sold between November 2020 and June 2022. A defect in cells supplied by a third party has been identified, and affected units are being replaced under warranty at no cost.

The recall doesn’t affect Powerwall 3, and Tesla has already discharged faulty units to make them safe. Here’s what you need to know if you own a Powerwall 2.

What’s Happening With the Tesla Powerwall 2 Recall in Australia?

Tesla has confirmed that a subset of Powerwall 2 units sold between 1 November 2020 and 30 June 2022 are affected by a manufacturing defect in battery cells supplied by a third party.

To address this, Tesla has launched a proactive recall. Every affected unit will be removed and replaced under warranty at no cost to the customer.

Affected Powerwalls in Australia and New Zealand have already been remotely discharged by Tesla, which renders them safe until replacement. The replacement process is being managed as part of Tesla’s normal warranty program, with product selection based on the site’s specific requirements.

Which Powerwall 2 Units Are Affected?

The recall only applies to a subset of Powerwall 2 batteries sold between 1 November 2020 and 30 June 2022.

Tesla has already identified the affected units. Customers with these batteries will see a notification in the Tesla app, while installers can confirm via Powerhub, where impacted systems appear with a “Powerwall Low Energy Lockout” alert.

If your Powerwall was purchased outside this date range, or if you own the Powerwall 3, you’re not affected by this recall.

Will My Solar System Still Work Without the Battery?

Yes. If your Powerwall 2 has been disabled, your solar panels will continue to generate electricity as normal. You’ll still be able to use that power in your home during the day.

What you won’t have during this period is backup power or the ability to store excess energy for night-time use. That functionality will return once the Tesla Powerwall 2 replacement unit has been installed.

How Do I Know If I’m Affected?

There are two simple ways to check:

For customers: Open the Tesla app. If your Powerwall 2 is part of the recall, you’ll see a notification explaining the situation.

For installers: Log into Powerhub. Affected systems will show an alert labelled “Powerwall Low Energy Lockout.”

If you don’t see an alert, your system isn’t impacted.

What is Tesla Doing to Fix It?

Tesla is replacing every affected Powerwall 2 at no cost to customers. The process is being managed through Tesla’s standard warranty program:

• Remote discharge for safety – Most faulty units have already been disabled remotely.
  
• On-site support – Tesla service teams are discharging the remaining units in person.
  
• Full replacement – Affected Powerwalls will be removed and swapped for a new battery. The replacement model will depend on your site’s requirements.
  
• Direct coordination – Customers are being contacted via the Tesla app, and installers are notified through Powerhub.

Tesla has stated that replacements are a priority and will be scheduled directly with certified installers.
