Storm Watch

Severe weather is the leading cause of grid outages. Storm Watch allows you to maximize 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 react in time to protect you during a severe weather event.

Powerwall communicates with the National Weather Service to know when severe weather is on the horizon and automatically triggers Storm Watch. 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 initiate Storm Watch or adjust its behavior, you can choose to disable this mode 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 is triggered during severe storms that are likely to knock down power lines and cause outages, such as high winds, hurricanes, severe thunderstorms, red flag warnings and tornados. Storm Watch activates when the weather event has advanced in severity, and a warning has been issued in your area. If Storm Watch 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 effectively protect yourself from everyday weather events or other grid instability, visit your utility provider’s website for updates.

How to Set Up Storm Watch

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

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

Your system is now in standby and will operate as normal, and your Powerwall will automatically react to severe weather events that may cause a grid outage. When active, Powerwall charges to full, protecting against outages.
