Powershare is a feature that is currently exclusive to the Cybertruck and one of the truck’s best selling points. With its massive 123kWh battery, the Cybertruck can supply power to your home when paired with a Tesla PowerShare setup. This system also includes automatic backup failover, ensuring seamless power during home outages.
Powershare Limitations
One major limitation has been that Tesla Powerwall owners couldn’t use the PowerShare feature due to software conflicts, which took a while to resolve.
However, the challenge wasn’t just software-related—Tesla also had to navigate several regulatory hurdles. A key issue was that homes with solar integrated into their backup solution couldn’t use PowerShare. This meant homeowners had to choose between powering their home with solar or their Cybertruck, rather than combining both sources.
Solar Update
Thanks to a recent update, PowerShare is now available for customers with solar in their backup circuit, allowing them to power their home with solar energy and even charge their Cybertruck during an outage—seamlessly and automatically.
Additionally, PowerShare is now enabled for customers with a backup switch, provided they are in an approved utility region.
Powerwall Update
PowerShare will be available to Powerwall owners using a Wall Connector Gen 3 or Universal Wall Connector starting in Q3 2025. While still a few months away, this is great news for Powerwall users looking to leverage the Cybertruck’s large battery as an extended backup power source for their homes.
Wall Connector Gen 3
Interestingly, Tesla has now enabled PowerShare for the Wall Connector Gen 3, a change that appears to be driven more by regulatory approvals than hardware or software limitations.
Currently, Tesla requires customers in the U.S. and Canada to use the Universal Wall Connector for PowerShare, even if they already own a Gen 3 Wall Connector. However, this policy will likely change in the coming months as the Gen 3 Wall Connector gains official support.
Author’s Note - Powershare Pricing
We’d love to see Tesla reduce the cost of PowerShare installation. The author received a quote for a home setup with two Wall Connectors in a standalone garage with its own breaker panel. Since the home already had an automatic Generac backup failover switch, much of the required electrical work was already in place.
Despite this, the final quote for installation came in just under $12,000 CAD (about $8,500 USD at the time). This covered only the installation of a Tesla Gateway, replacing a single Gen 3 Wall Connector with a Universal Connector, and some additional wiring. Even with the Foundation-Series discount of $3,500 CAD, it won’t be cheap to install.
While this update is a great step forward, Tesla needs to make PowerShare more accessible—both by expanding it to more vehicles and by lowering installation costs. It’s an incredibly useful feature that will help sell vehicles, but affordability remains an issue.
