Can your Tesla keep your lights on when the power goes out? 🔌🏠
As of October 2026, Tesla's Powershare Home Backup works with the Model 3 and Model Y, not just the Cybertruck. Paired with a Powerwall 3, your car can extend your home's backup power during an outage.
Before you shop for a new car, read the fine print:
✅ You need a Powerwall 3 and a Universal Wall Connector or Wall Connector 3
✅ Every Model 3 and Model Y ordered on or after October 1, 2026 qualifies
✅ Some older cars qualify too, and you can check yours on the touchscreen in seconds
⚠️ It's backup only, so it won't sell energy back to the grid
From summer heat and monsoon storms to wildfire safety shutoffs and winter snow, Arizona homeowners have plenty of reasons to plan for outages.
