Powershare Helps You Get More from Your Cybertruck

With Powershare, you can use your Cybertruck battery to power your home or the grid.

What is Powershare

Powershare bidirectional charging technology turns equipped Tesla vehicles into mobile power banks, enabling energy to flow to and from the battery. For Cybertruck, this means a fully charged vehicle can power an average home for over three days¹ during an outage with Powershare Home Backup. With Powershare Grid Support, stored energy can also be sent back to the grid, earning owners compensation in return.

For Powershare to work, the energy stored in the battery of Cybertruck needs to be converted from direct current (DC) to alternating current (AC) power, which is how both home appliances and the grid are powered. This conversion from DC to AC is done through the vehicle's built-in inverter. That means owners only need to add Powershare Gateway and Universal Wall Connector to use Powershare, keeping installation simple and costs low.

Powershare Home Backup

Powershare Home Backup, Tesla’s vehicle-to-home (V2H) technology, provides backup power to homes using the energy stored in the battery of Cybertruck.

The touchscreen of your Cybertruck shows approximately how many days of energy you have remaining when Powershare Home Backup is activated. You can adjust your discharge limit anytime in the Tesla app.

When a grid outage occurs and your vehicle is plugged in, Powershare Gateway automatically detects loss of power and signals Cybertruck to begin discharging, allowing the home to switch from grid power to vehicle power within one minute². With Universal Wall Connector, Cybertruck can deliver up to 11.5 kW of continuous power to keep lights, appliances, Wi-Fi and other critical systems running. It is a cleaner and quieter alternative to traditional generators, requiring no fuel storage, regular maintenance or manual operation.

To extend backup duration, owners can pair Cybertruck with Tesla Solar Panels to recharge their vehicle’s battery during the day.

Compatibility With Powerwall

Powershare Home Backup will soon support Powerwall. 

Once available, your plugged-in Cybertruck will be able to add extra energy storage to extend Powerwall backup time by three days while Powerwall helps run high-demand appliances, no additional equipment required. When your Cybertruck is on the road, Powerwall continues to provide your home with backup electricity.

Powershare Grid Support 

In addition to powering homes, Powershare Grid Support, Tesla’s vehicle-to-grid (V2G) technology, enables Cybertruck to send stored energy to the grid during periods of high demand, earning owners compensation for contributing to their community's energy resilience. Cybertruck can determine when to recharge and send energy back to the grid based on market conditions and the owner's system preferences.

Powershare Grid Support is currently available to owners in parts of California and Texas³ and requires no additional equipment beyond what's already installed for Powershare Home Backup. Owners who wish to enable Powershare Grid Support should inform their Tesla Certified Installer to ensure the installation meets local electrical codes for safely exporting power back to the grid.

How It Works in California

In California, Powershare Grid Support allows owners to participate in virtual power plants⁴ (VPPs), which are utility-powered programs designed to support grid stability when electricity demand fluctuates. These programs are available through the Emergency Load Reduction Program⁵ (ELRP) for customers of Pacific Gas and Electric Company (PG&E), Southern California Edison (SCE) and San Diego Gas and Electric (SDG&E).

Between May and October, owners can expect to support 30 to 60 hours of grid events per year, with each event lasting one to three hours.⁶ 

Participation in VPPs can earn owners up to $690 in cash per year, calculated at $2 for every kWh their vehicle delivers back to the grid during an event.

How It Works in Texas

Powershare Grid Support in Texas is facilitated by Tesla Electric, allowing enrolled customers to sell their electricity directly on the open market when electricity rates are high and earn credits on their electricity bill in return.

Based on historical market data⁷, enrolled owners could have participated in approximately 20 events annually over the last three years and earned over $1,500 during that period.⁸

Manage Everything Through the Tesla App

Both Powershare Home Backup and Powershare Grid Support can be enrolled in, tracked and managed through the Tesla app, providing real-time visibility into energy usage and backup power status.

For owners who want to test their setup by simulating a power outage, Go Off-Grid mode temporarily disconnects the home from the grid, even if power is available. When activated, the home runs only on the battery power provided by Cybertruck and solar energy (if available). The Tesla app monitors remaining backup duration and automatically reconnects to the grid if energy demand exceeds system capacity.

Driving Always Comes First

Powershare is designed to work around the owner's driving needs. Through the Tesla app, owners can set a minimum charge level, ensuring the Cybertruck always retains enough range for daily use. Neither Powershare Home Backup nor Powershare Grid Support will require the vehicle to discharge below this threshold.

Owners can also schedule their departure time to ensure their vehicle is fully charged and ready when needed. When grid events occur, owners are notified and may choose to participate or opt out.

Participating in Powershare Grid Support does not impact vehicle warranties.⁹ Tesla's battery management system ensures that all charging and discharging occur within optimal parameters.

Getting Started With Powershare

Cybertruck owners will find that Powershare expands their vehicle's usefulness beyond transportation. Rather than sitting idle at home, it becomes a functional part of the home energy ecosystem, increasing its overall value while providing long-term energy independence.
