Tesla has informed Cybertruck owners that the Powershare with Powerwall feature, which integrates the vehicle's battery as an extended home backup, will not arrive until mid-2026. The delay stems from technical complexities in ensuring compatibility across various Powerwall configurations. Owners, many of whom paid extra for the promised capability, have voiced disappointment over the repeated postponements.
Powershare, announced in late 2023, is a bidirectional charging system exclusive to the Cybertruck. It enables the truck's battery to supply up to 11.5 kW of power to homes, appliances, tools, other electric vehicles, and more, supporting both vehicle-to-load (V2L) and vehicle-to-home (V2H) applications. This feature positions the Cybertruck as a portable power source, particularly useful during outages, with Powerwall integration allowing the truck to act as an extended battery while prioritizing Powerwall discharge.
Despite initial expectations for a late 2024 release, Tesla recently emailed owners stating the feature remains in development. "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," the email read. "This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy."
Foundation Series Cybertruck buyers, who incurred extra costs anticipating the feature at delivery, have expressed frustration over the delays. Cybertruck Lead Engineer Wes Morrill acknowledged the challenges on X, posting: "As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments. To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…"
Morrill further explained the hurdles: "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 the 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."
While Tesla has implemented Powershare for some setups, including solar-only homes and via the Powershare Gateway, full Powerwall compatibility awaits further refinement. The company emphasizes its commitment to safety and reliability amid these setbacks.
