Tesla Powershare vehicle-to-home backup

Plug in your compatible Tesla. Power through an outage.

The battery already parked in your driveway may be able to support your home when the grid goes down. Tesla Powershare connects a compatible Cybertruck, Model 3 or Model Y with the home's electrical and energy equipment for vehicle-to-home backup. Eco Solar & Electric verifies the vehicle first, then designs the Wall Connector, Powerwall, Gateway, Backup Switch, solar and backed-up loads as one coordinated system.

Vehicle-to-home energy

Your Tesla may be more than transportation. It may be backup power already sitting in the driveway.

Powershare creates a new bridge between the vehicle and the home. The opportunity begins with a Wall Connector and grows into a coordinated backup system with the right Tesla vehicle, Powerwall, solar and electrical design.

Published Tesla capabilities are not a promise that every vehicle, home or load qualifies. Actual backup power and duration depend on the vehicle, state of charge, equipment, electrical design, software, loads, permits and site conditions.

02 / Unlock vehicle-to-home

Powershare

Confirm the vehicle's Powershare Support field, calculate the loads and determine whether the property needs Powerwall, a Powershare Gateway, Universal Wall Connector, Backup Switch or an essential-load panel.

03 / Build the ecosystem

Powerwall + Solar

Keep stationary backup available when the vehicle is away, coordinate solar during suitable outage conditions and evaluate the new Powerwall 2-to-Powerwall 3 expansion path.

Choose the backup target

Whole home or the loads that matter most?

Lighting, refrigerators, internet, garage equipment, selected receptacles and other essentials may need a different design than air conditioning, electric cooking, water heating, laundry or pool equipment. We document starting and continuous loads before defining the backup scope.

Powerwall makes Powershare bigger

Keep backup at the house—even when the car leaves.

Model 3 and Model Y currently require Powerwall for Powershare Home Backup. Powerwall can also strengthen a Cybertruck pathway, coordinate stationary storage with solar and preserve a home-energy foundation beyond the vehicle.

Vehicle check

Do not guess whether the car qualifies.

In the vehicle touchscreen, open Controls → Software → Additional Vehicle Information. Powershare Support must show Enabled. Tesla currently lists Cybertruck plus compatible Model 3 and Model Y vehicles.

Existing Powerwall check

Powerwall 2 may now have an expansion path.

Eligible systems on software 26.26 or later can support one Powerwall 3, up to three Powerwall 3 Expansion units and up to four existing Powerwall 2 units. Gateway, metering and Powerwall+ limitations still apply.

Compatibility, backup duration, permitting and final equipment depend on the exact vehicle, software, Tesla account/site registration, existing energy equipment, utility/AHJ requirements, panel capacity, loads and site conditions. Eco Solar & Electric verifies current Tesla documentation and installed equipment before quoting. Tesla product names and specifications belong to Tesla, Inc.

Questions customers ask

Direct answers before you call.

What is Tesla Powershare vehicle-to-home backup?

Powershare allows an eligible Tesla vehicle battery to supply energy to a compatible home electrical system during an outage. It is more than ordinary vehicle charging: the vehicle, Wall Connector, Powerwall or Powershare equipment, meter, panel, backed-up loads, software and Tesla site registration must form an approved configuration.

Can every Tesla vehicle power a home?

No. Tesla currently identifies Cybertruck and compatible Model 3 and Model Y vehicles for Powershare. All Cybertruck trims qualify. New Model 3 and Model Y vehicles ordered in the U.S. or Puerto Rico after October 1, 2026 are capable by default, while some earlier vehicles qualify. In the vehicle, open Controls, Software and Additional Vehicle Information; the Powershare Support field must show Enabled.

Can Model 3 or Model Y provide home backup without Powerwall?

Tesla currently requires Powerwall for Model 3 and Model Y home-backup use. Cybertruck can support certain standalone configurations using a Powershare Gateway and Universal Wall Connector. The home's meter, panel, solar and backup-load arrangement still determine the approved design.

Do I need a special Wall Connector for Powershare?

For a system with Powerwall, Tesla lists either Universal Wall Connector or Wall Connector 3. A standalone Cybertruck home-backup configuration requires Universal Wall Connector and Powershare Gateway. The Wall Connector and Powerwall must be registered to the same Tesla site and paired on the same Wi-Fi network.

Can Powerwall 3 be added to an existing Powerwall 2 system?

Yes, for eligible systems using Powerwall software version 26.26 or later. Tesla's launch configuration supports up to four Powerwall 2 units, one Powerwall 3 and up to three Powerwall 3 Expansion units. Gateway 1, Powerwall+ and Neurio Meter configurations require changes and are not supported as-is.

How long can a compatible Tesla back up a home?

Tesla publishes estimates ranging from up to two days for Model 3 Standard and Model Y Standard to over two days for Premium and Performance trims, and over three days for Cybertruck. Those estimates assume an average U.S. home using 30 kWh per day and a vehicle at 90% state of charge; actual duration varies with loads, vehicle, solar and battery charge.

Can Powershare run air conditioning or other 240-volt equipment?

Potentially, but only when the vehicle, equipment and approved home-backup design support the required voltage, starting current and continuous load. Tesla states Cybertruck can support 120-volt and 240-volt loads in qualifying whole-home configurations. With Powerwall, compatible Model 3, Model Y and Cybertruck vehicles can extend backup for essentials and larger appliances. We calculate loads and define whole-home or essential-load backup before quoting.

Does Powershare replace Powerwall?

Not in every configuration. Model 3 and Model Y currently require Powerwall for home backup. Cybertruck may support certain standalone systems with a Powershare Gateway and Universal Wall Connector. Powerwall can also keep stationary backup available when the vehicle is away and can coordinate with solar, subject to the approved design.

What should I send for the complimentary remote preflight?

Send the city, Tesla model and trim, order or delivery date, a photo of the vehicle's Additional Vehicle Information screen, and safe photos of the closed main panel, meter, Wall Connector, Powerwall, gateway and solar equipment. Do not remove electrical covers.

Field experience

The car, charger, battery, solar and home should work as one energy system.

A Wall Connector can be the first practical step toward a larger Tesla home-energy system. If the vehicle and property qualify, Powershare can add the vehicle battery to the outage plan; Powerwall can make Model 3 and Model Y home backup possible and strengthen the pathway for Cybertruck; eligible Powerwall 2 owners may now have a supported Powerwall 3 expansion path. Every configuration is verified against the vehicle, installed equipment, current Tesla guidance and local requirements before quoting.
