Tesla has confirmed another significant delay to one of the Cybertruck’s most anticipated energy features. In a new email sent directly to customers on Thursday night, a copy of which was shared with Drive Tesla by one of our readers, the company says PowerShare with Powerwall is now scheduled for release in mid-2026, pushing compatibility nearly a full calendar year later than previously expected.
The update means Cybertruck owners with existing Powerwall systems will wait close to three years after the Cybertruck’s launch before being able to use their vehicle as an integrated home backup power source alongside Tesla’s stationary batteries.
“We’re writing to let you know that the PowerShare with Powerwall feature is still in development and is now scheduled for release in mid-2026,” Tesla wrote in the email.
The company said the additional time is needed to ensure the system can “communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall.”
UPDATE 8:57am PT: In a post on X, Cybertruck lead engineer Wes Morrill explained the reason behind the delay.
“It turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid forming devices need to negotiate who will form and who will follow depending on state of charge of each, and they need to do this without a network and through multiple generations of hardware and test and validate this process through rigorous certifications to ensure grid safety.”
What PowerShare With Powerwall Is Meant to Do
PowerShare is Tesla’s bidirectional charging system, debuting with the Cybertruck, that allows the truck’s massive battery to supply power outward. This includes powering tools and appliances, charging another EV, or running an entire home during an outage.
While Cybertruck Vehicle-to-home power (V2H) is already available through Tesla’s PowerShare Gateway and Universal Wall Connector, the missing piece has been native integration with Powerwall systems. Tesla’s long-term vision is for Powerwall to act as an energy buffer while the Cybertruck effectively becomes a large, mobile extension of the home battery system—dramatically extending backup duration during outages.
Why the Delay Matters
Many Cybertruck owners already invested in Powerwall installations expecting seamless integration. Instead, they remain unable to use the two systems together, even though both are fully Tesla products.
Tesla says the delay allows time to test across multiple Powerwall generations, solar configurations, and electrical layouts, highlighting the complexity of managing bidirectional energy flows safely and reliably. Home backup systems must meet strict regulatory and utility requirements, and coordinating vehicle firmware, Powerwall software, and Tesla app controls adds another layer of complexity.
Tesla also noted it is using the extended timeline to develop additional PowerShare features, though no specifics of these new features were shared.
What Owners Can Do Today
Cybertruck owners can still use PowerShare without Powerwall, provided they have the required PowerShare Gateway and compatible Wall Connector installed. In that configuration, the Cybertruck can automatically power a home during a grid outage.
However, Powerwall-equipped homes remain locked out of full integration until at least Q2 or Q3 2026, based on Tesla’s new “mid-2026” guidance.
