One Tesla Powerwall owner says that after the company remotely disabled their recalled home battery without warning, they were slated to be shut out of service until February.

Unfortunately, they only found this out after a blackout, when the Tesla app showed the unit had been shut down. The homeowner then shared their story on Reddit's r/Powerwall community.

Here's what to know

On the Reddit forum, the homeowner said the company had already deactivated a recalled component in their Powerwall before they received any notice. 

This original poster also wrote that several days of back-and-forth with customer support ended with instructions to schedule service for February, many months later. The four-to-five-month delay raised concerns that OP would have no backup power for the upcoming El Niño winter.

Other Powerwall owners streamed into the thread to share their thoughts, similar stories, and recommendations.

One owner said their units "have not worked since April" and that they finally got a December appointment, while a commenter in Texas said three of their four Powerwalls had been disabled and would not be replaced until December.

Commenters also focused on the combination of remote shutdowns, no notice, and long waits for replacement. If a Powerwall goes offline, homeowners can be left tied to the grid during an outage instead of drawing on stored energy in the expensive system that they paid for.

One commenter emphasized they were "losing money by being grid tied. Seems like a case for a class action," and another said they were still checking every few days for a shutdown notice.

What can be done?

The most common advice was to check the battery's status in the app, contact the company directly, and get a firm replacement date instead of assuming the system will be ready for the next outage.

The thread also mentioned outside installers. One commenter said that in some areas, "there are a few companies that for a fee will replace it with one of theirs in stock and take the warranty replacement to refill their stock when it finally comes in."

Homeowners weighing backup options may want to explore EnergySage to compare home battery storage options and competitive installation estimates. EnergySage has teamed up with electrification brand Qmerit to help homeowners get the best price on home battery storage solutions.

For homeowners still comparing options, or who want supplemental backup while planning a larger system, Pila offers another strong battery option. Pila's plug-and-play batteries cost a fraction of a whole-home backup system and can back up individual appliances.

But as this story shows, battery storage is only useful as a resilience tool if owners know their equipment's status and have a clear service path when something is recalled.
