Storm Watch

Severe weather is the leading cause of grid outages. Storm Watch allows you to maximise savings by keeping a low backup reserve percentage in Self-Powered or Time-Based Control mode, while still having peace of mind that Powerwall will automatically react to protect you during a severe weather event.

When Storm Watch is enabled, Powerwall will automatically activate Storm Watch mode when the National Weather Service sends a severe weather alert. This mode pushes the limits and charges Powerwall to maximum capacity so it can provide backup power.

You will receive an app notification when Storm Watch mode is activated. This remains active until the weather event ends, and your system will return to its previously selected mode. Although you cannot manually activate Storm Watch mode or adjust its behavior, you can choose to disable Storm Watch altogether by going to the Tesla app, tapping on the ‘Settings’ screen and disabling 'Storm Watch.’ You can re-enable Storm Watch at any time during a weather event.

Severe Weather Events

Storm Watch mode is triggered during severe storms that are more likely to knock down power lines and cause outages. Storm Watch mode activates when the weather event has advanced in severity, and one of the following watches or warnings has been issued in your local area:


If Storm Watch mode hasn’t activated based on your local weather conditions, and you prefer additional energy security, set a higher Backup Reserve in advance of an anticipated grid outage.

Note: To better prepare yourself for everyday weather events or other grid instability, visit your utility provider’s website for updates.

How to Enable Storm Watch

Step 1: From the home screen, open the ‘Settings’ menu.

Step 2: Scroll down, and then enable ‘Storm Watch.’

Your system will continue to operate as normal, and your Powerwall will automatically react to severe weather events that may cause a grid outage. When Storm Watch mode activates due to a severe weather event in your area, Powerwall charges to full, protecting against outages.
