As of October 2026, new Model 3, Model Y and Cybertruck owners can use their vehicles to power their homes during an outage. Power Northwest installs the Powerwall 3, Powershare Gateway and EV chargers that make vehicle-to-home backup work in Portland.
A smarter way to stay powered
Powershare lets a compatible Tesla send the energy stored in its battery back into your home. When the power goes out, your car becomes part of your home’s backup system.
2+ days
Extra backup Tesla estimates for an eligible Model 3 or Model Y Premium or Performance with Powerwall 3*
11.5 kW
Continuous power to your home, the same output as a Powerwall 3*
0 gas
No generator fuel, fumes or noise during an outage
*Tesla estimates for a home using about 30 kWh a day, starting from a 90% vehicle charge. Standard trims add up to two days and Cybertruck adds over three. Actual backup time depends on your vehicle, home and installation.
Tesla Powershare is bidirectional charging: energy can flow out of your Tesla vehicle’s battery, not just into it. Powershare Home Backup is the vehicle-to-home (V2H) feature. When the grid goes down, your plugged-in Tesla feeds your home through the Wall Connector and interconnected Powerwall 3 or Powershare Gateway.
Tesla extended Powershare Home Backup to Model 3 and Model Y on October 6, 2026, after launching Cybertruck support with Powerwall 3 in September 2026. For Portland homeowners, that means the biggest battery you own can now keep your lights, furnace and fridge running.

A single Powerwall 3 alone typically provides 12-24 hours of backup power. Add your Tesla, and Tesla estimates two or more extra days for an average home.
Your car delivers up to 11.5 kW through your home's wiring, the same output as a Powerwall 3. Enough for heat pumps, well pumps and laundry, not just phone chargers.
Silent, no fumes, nothing to refuel. No extension cords through a cracked window.
Set how far your car can discharge so there's always enough left to drive to work or evacuate.
All new Model 3 and Model Y vehicles ordered in the US on or after October 1, 2026 are Powershare-capable and require a Powerwall 3 at home.
Cybertruck models now offer V2H through a Powerwall 3 (preferred) or a Powershare Gateway connection.
On a Model 3 or Model Y ordered before October 1, 2026, open Software > Additional Vehicle Info on the touchscreen and look for “Powershare Support: Enabled.”
Have a Powerwall 2 or Powerwall+? Tesla has said support is coming, targeted for late 2026.
How installation works
There are two common paths to Powershare Home Backup. Your vehicle and the equipment you already have decide which one fits.
Option 1: With Powerwall 3
Pair an eligible Model 3, Model Y or Cybertruck with Powerwall 3 and a Tesla Wall Connector to extend your home backup.
Option 2: Cybertruck without Powerwall
Cybertruck owners can back up their home without a Powerwall, using a Powershare Gateway and a Universal Wall Connector.
Tesla lists Powerwall 2 and Powerwall+ support as coming soon. A Powershare Gateway can’t be installed on the same system as a Powerwall. Add solar and you can recharge your Powerwall and your Tesla while the grid is down. We confirm the right equipment for your home in your quote.
From the January 2024 ice storm to wildfire Public Safety Power Shutoffs, Portland-area homes know outages can last days. Take advantage of today’s phenomenal battery incentives so you’re prepared for the next big outage.
Energy Trust battery incentives require the battery to be connected to a qualifying solar system.
Incentives change. We’ll confirm what you qualify for in your quote.

Yes. Tesla currently requires a Powerwall 3 and a compatible Wall Connector for Model 3 and Model Y home backup. Cybertruck can also back up a home with a Powershare Gateway and Universal Wall Connector.
Tesla estimates over two days for Model 3 and Model Y Premium and Performance, up to two days for Standard, and over three days for Cybertruck, based on 30 kWh per day. A home with electric heat in winter may use more.
If your Wall Connector is on your backed-up circuit and shares Wi-Fi with your Powerwall, Powershare is enabled by software update. We can check your setup.
Not with Model 3 or Model Y yet. Powershare Grid Support is currently limited to Cybertruck in select markets.
You set the discharge limit, and Tesla’s battery management keeps charging and discharging within its parameters. See Tesla’s warranty terms for details.
The 30% federal residential credit ended for systems installed after December 31, 2025. Oregon incentives through Energy Trust are still available.
