Vehicle-to-Home Backup

Your Tesla Can Do More Than Drive.

Tesla Powershare allows compatible Tesla vehicles to send electricity from their battery to your home during a power outage.

Instead of relying entirely on a separate stationary battery, you can use energy already stored in your vehicle.

How Does Powershare Work?

  1. Your Tesla Is Connected at Home

    Park your compatible Tesla and connect it to the appropriate Tesla Wall Connector.

  2. The System Detects an Outage

    When utility power is lost, compatible backup equipment isolates your home from the grid and enables the supported backup configuration.

  3. Your Vehicle Supplies Electricity

    Energy stored in your vehicle can help power the electrical circuits included in your backup system.

  4. Monitor Through the Tesla App

    View backup activity, available battery energy, and system information through the Tesla app.

What Can Powershare Run?

Depending on your vehicle and installation configuration, Powershare can support:

  • Refrigerators and freezers
  • Lighting
  • Internet and Wi-Fi equipment
  • Home office equipment
  • Essential outlets
  • Selected appliances
  • Additional household loads, when supported by the system design

Larger equipment, including air conditioning and electric heating, requires an evaluation of electrical demand and available backup power.

Important: Your Tesla must be connected at home, have sufficient battery charge, and meet the applicable system requirements to supply backup power.

Compatible Tesla Vehicles

Which Tesla Vehicles Support Powershare?

Powershare Home Backup is available on compatible Cybertruck, Model 3, and Model Y vehicles.

The equipment required depends on the vehicle and whether the home already has Tesla Powerwall 3.

    Tesla Cybertruck

    All Cybertruck trims support Powershare.

    Cybertruck can provide home backup through either:

    • A standalone Powershare installation without Powerwall
    • A compatible Powerwall 3 system with supported charging equipment

    For homeowners who already own a Cybertruck, standalone Powershare may be an option without purchasing a separate home battery.

  • Illustration of a white Tesla Model Y parked in a concrete garageIllustration

    Tesla Model Y

    Compatible Model Y vehicles can provide home backup when paired with Powerwall 3 and a supported Wall Connector.

    Tesla states that all Model Y vehicles ordered in the United States and Puerto Rico after October 1, 2026, support Powershare. Some earlier vehicles are also eligible.

  • Illustration of a white Tesla Model 3 parked in a concrete garageIllustration

    Tesla Model 3

    Compatible Model 3 vehicles can also provide home backup using Powerwall 3 and a supported Wall Connector.

    Tesla states that all Model 3 vehicles ordered in the United States and Puerto Rico after October 1, 2026, support Powershare. Some earlier vehicles are also eligible.

How to Confirm Your Vehicle Supports Powershare

For Model 3 and Model Y, Tesla provides a way to confirm eligibility directly from the vehicle.

  1. Update your vehicle to firmware version 2026.32.6 or later.

  2. Open Software on your vehicle touchscreen.

  3. Select Additional Vehicle Information.

  4. Look for Powershare Support: Enabled.

If your vehicle shows that Powershare is enabled, the next step is to determine whether your home has the required equipment.

Model S and Model X do not currently support Powershare Home Backup.

Understanding the Installation

What Equipment Do You Need for Tesla Powershare?

There are two main ways to install Powershare Home Backup.

The correct approach depends on your Tesla vehicle and whether you already have a Powerwall 3 system.

Option 1: Powershare Without Powerwall

For eligible Tesla Cybertruck owners

A standalone Cybertruck Powershare installation generally requires:

  • A compatible Cybertruck
  • Tesla Powershare Gateway
  • Tesla Universal Wall Connector
  • Required wiring, circuit protection, and electrical connections
  • A suitable home backup configuration

Certain electrical configurations may also use a Tesla Backup Switch.

What Does the Powershare Gateway Do?

The Powershare Gateway manages the connection between your home, vehicle, and utility grid.

It detects power outages and helps isolate the home's electrical system so the vehicle can provide backup electricity safely.

The Universal Wall Connector provides the compatible connection between the Cybertruck and the home's installed equipment.

Do You Need to Buy Powerwall 3?

No. Cybertruck can provide home backup through a supported standalone Powershare configuration without purchasing Powerwall 3.

Option 2: Powershare With Powerwall 3

For compatible Cybertruck, Model 3, and Model Y owners

If your home has a supported Powerwall 3 installation, Powershare can use:

  • Tesla Powerwall 3
  • Tesla Universal Wall Connector or Gen 3 Wall Connector
  • A Powershare-compatible vehicle
  • Supported Tesla software, networking, and equipment configuration

A separate Powershare Gateway is not used with a Powerwall system.

For this configuration, the Powerwall and Wall Connector must be connected to the same Wi-Fi network, registered to the same Tesla site, and paired appropriately. Tesla may also need to enable Powershare functionality.

Already Have an Older Powerwall?

Powershare functionality with Powerwall 2 and Powerwall+ is not yet available under Tesla's current published compatibility guidance.

We'll verify the latest manufacturer support before recommending changes to an existing installation.

Planning to Add Powerwall Later?

Tell us before installing standalone Cybertruck Powershare.

Tesla recommends installing Powerwall first when both systems are planned. This can help avoid unnecessary electrical work or replacing equipment later.

Planning Your Backup Power

How Much of Your Home Can Powershare Support?

Powershare can be configured for whole-home or partial-home backup, depending on the equipment, electrical loads, and supported system design.

Essential-Circuit Backup

Some homeowners want to keep the most important parts of their home operating during an outage.

That may include refrigeration, lighting, internet equipment, and selected outlets.

Limiting backup to essential circuits can help extend the amount of time stored energy remains available.

Whole-Home Backup

A whole-home backup system may support a broader range of household electrical loads.

However, high-demand appliances can affect how much power is available and how long the vehicle battery lasts.

We evaluate the electrical requirements of your home before recommending a backup configuration.

How Long Can Cybertruck Power a Home?

Tesla estimates that a Cybertruck with Powershare Home Backup can provide more than three days of backup electricity under its reference conditions.

That estimate is based on typical household consumption of approximately 30 kWh per day and a vehicle battery at 90% charge.

Your actual backup duration may be shorter or longer depending on:

  • Vehicle model and battery capacity
  • Battery charge when the outage begins
  • Household electrical demand
  • Heating and air-conditioning usage
  • Backup configuration
  • Solar energy production, if available
  • Battery energy reserved for driving

Compatible Model 3 and Model Y vehicles have different battery capacities and backup-duration estimates.

Does Powershare Mean Unlimited Backup Power?

No.

Powershare uses electricity stored in your vehicle battery. When that available energy is depleted, it can no longer support the home unless the system receives additional energy through a supported charging configuration.

We'll help you plan backup priorities based on the loads you want to support.

Comparing Your Options

Tesla Powershare or Powerwall 3: Which Do You Need?

Both systems can help provide electricity during an outage, but they work differently.

Tesla Powershare

Uses energy stored in a compatible vehicle battery.

The vehicle must be parked at home and connected to the supported charging equipment when providing home backup.

For eligible Cybertruck owners, Powershare can be installed without a separate Powerwall battery.

Tesla Powerwall 3

A stationary home battery installed at your property.

Powerwall remains available for home backup when your vehicle is away, provided the battery has sufficient stored energy.

It can be configured with or without solar panels.

Can You Install Both?

Yes.

A compatible Tesla vehicle can work with Powerwall 3 to extend backup duration during longer outages.

For homeowners who want stationary battery backup as well as access to energy stored in their Tesla, the combination may be worth considering.

The appropriate choice depends on your vehicle, backup goals, existing solar system, and installation requirements.

Understanding Installation Costs

How Much Does Tesla Powershare Installation Cost?

The cost of installing Tesla Powershare depends on the vehicle, existing electrical equipment, and backup configuration.

A standalone Cybertruck Powershare installation will have different equipment requirements from a home that already has a compatible Powerwall 3 system.

What Can Affect Your Estimate?

  • Required Powershare Gateway, if applicable
  • Universal or Gen 3 Wall Connector requirements
  • Existing electrical panel and service capacity
  • Required electrical circuits and wiring
  • Distance between charging equipment and electrical panels
  • Backup Switch or load-center modifications, where needed
  • Backup configuration and circuit selection
  • Permit and inspection requirements
  • Applicable utility coordination

Do You Need to Upgrade Your Electrical Panel?

Not necessarily.

Some homes have an electrical system suitable for the proposed equipment. Others may require panel modifications or an electrical service upgrade.

We'll review the existing panel and electrical capacity before recommending additional work.
