Severe weather is the leading cause of power outages. Storm Watch mode allows you to maximize savings by keeping a low reserve percentage in Self-Powered or Time-Based Control mode, while still having peace of mind that Powerwall will 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.
When activated, the Tesla app will notify you that you are now in Storm Watch mode. This remains active until the weather event ends. After, the system returns to its previously selected mode. Although you cannot turn on Storm Watch or adjust it, you can disable this mode altogether by going to the Tesla app, selecting 'Customize' and adjusting the slider next to 'Storm Watch'.
Note that Storm Watch only activates during severe storms that are likely to knock down power lines and cause outages, like hurricanes and ice storms. To best protect yourself from everyday weather events, keep a high reserve percentage or choose Backup-Only. As your Powerwall learns more about the type of storms that typically cause outages, events that trigger Storm Watch will be adjusted.
- From the home screen, tap ‘Customize.’
- Scroll down to the bottom of the screen and tap the slider to turn on Storm Watch.
- The Powerwall is now in standby for Storm Watch. This is what the Tesla app looks like in standby.
