Before You Start

  1. Make sure there's no power outage in your area.
  2. Turn off any sensitive electronics if you're worried about brief interruptions.
  3. You’ll need access to your Powerwall unit and your main electrical panel (or subpanel feeding the Powerwall).

Step 1.3: Flip the switch to OFF. This shuts off the battery's internal systems.

Step 2.3:  Flip that breaker to OFF. This completely shuts down power to the Powerwall.


3. Wait for 1 Minute

Step 3.1: Give your system a moment to rest; waiting 1 full minute helps everything reset properly.


4. Turn the System Back On

Step 4.1: Turn the Breaker Back ON

  • Step 4.1.1: Go back to the breaker panel and flip the Powerwall breaker back to ON.

Step 4.2: Turn the Powerwall Switch Back ON

Step 4.3: You should hear the system hum slightly or see indicator lights as it boots up. This may take a few minutes.


5. Check the Tesla App

Step 5.1: Open your Tesla app.

Step 5.2: The Powerwall should show as “Connected” and display normal charging/discharging behavior.

Step 5.3: If it still shows as offline after 5–10 minutes, try restarting your phone or refreshing the app.
