Tesla has announced yet another recall, though this one does not pertain to its electric vehicles. On Thursday, the company revealed a recall for its Powerwall 2 AC Battery System, launching a replacement initiative for roughly 10,500 impacted units in the U.S. The Powerwall 2 AC Battery System is designed for residential or light commercial energy storage, utilizing solar power or the grid.

The U.S. Consumer Product Safety Commission (CPSC) indicated that “the lithium-ion battery cells in certain Powerwall 2 systems can lead to the unit ceasing to operate during regular use.” A defective unit may overheat and is at risk of smoking or catching fire, posing dangers of fatality or severe injury due to fire and burn risks, as per the official CPSC recall announcement.

The impacted units were sold via Tesla’s website and through certified installation technicians for $8,000 between November 2020 and December 2022. Tesla has attributed the problem to a “third-party battery cell defect.”

The CPSC has documented 22 instances of the Powerwall 2 AC Battery System overheating, including six cases involving smoking units and five that led to fires, resulting in minor property damage. There have been no reported injuries.

Tesla has “remotely discharged” nearly all of the affected units, thereby removing the risk. Any units that remain will be manually discharged by technicians. All impacted Powerwall 2 units will be replaced at no expense to customers.

Owners of Powerwall 2 should check their Tesla app for further updates.
