Tesla Powershare, Wall Connector and Powerwall

Your compatible Tesla can help power your home. Start with the right home-energy plan.

Tesla Powershare can use the battery in a compatible Cybertruck, Model 3 or Model Y to support the home during an outage. The required equipment depends on the vehicle and the home's existing Powerwall, solar, meter and electrical-panel configuration. Eco Solar & Electric verifies eligibility first, then designs the Wall Connector, Powershare, Powerwall or solar scope around the property instead of treating every home the same.

One customer journey. Three opportunities.

Charge the car. Prepare the home. Build the energy system.

We start with what the customer owns today and create an upgrade path without pretending every vehicle or property qualifies for the same equipment.

01 / Home charging

Wall Connector

Plan the circuit, panel capacity, routing, permits, commissioning and Tesla app registration for dependable Level 2 charging.

Request a Wall Connector review →
02 / Outage support

Powershare

Verify the vehicle's Powershare Support field and determine whether the home needs Powerwall, a Powershare Gateway, Universal Wall Connector, Backup Switch or load relocation.

03 / Energy independence

Powerwall + Solar

Assess backup loads, existing solar, eligible Powerwall 2 expansion, Powerwall 3, future storage and solar production as one coordinated system.

Request a Powerwall and solar review →

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 the current Tesla documentation and installed equipment before quoting.

Questions customers ask

Direct answers before you call.

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.

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

One electrical plan can connect home charging, vehicle backup, Powerwall and solar.

A Wall Connector can be the first practical step. If the vehicle and home qualify, Powershare can extend outage backup through Powerwall; eligible Powerwall 2 owners may now have a supported Powerwall 3 expansion path. Solar can help recharge the home's energy ecosystem during suitable outage conditions. Every claim and configuration is verified against the installed equipment, current Tesla software and local requirements before quoting.
