System Alerts and Notifications

When your Powerwall system changes status, such as when Going Off-Grid or entering Storm Watch mode, you can receive push notifications to your phone. To receive push notifications, both your phone and Powerwall must be connected to the internet.

Internet connection may be unavailable during some grid outages, preventing delivery of Tesla app notifications. However, even without internet connection, your Powerwall is expected to operate normally during an outage.

The following tables outline typical Powerwall events and their expected push notifications:

Off-Grid and Grid Outages
