Storm Watch

Severe weather is the leading cause of grid outages. Storm Watch ensures that your Powerwall has enough stored energy to power the home in the event of a grid outage. You can 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 automatically react to protect you during a severe weather event.

Storm Watch is currently available for the U.S., United Kingdom, Thailand, Japan, Taiwan, Australia and New Zealand.

How It Works

Storm Watch mode is triggered only during severe weather events that are more likely to damage power lines and cause power 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:

When Storm Watch is activated, you will receive a push notification, and Powerwall will charge to maximum capacity to automatically maximize your protection from grid outages. This remains active until the weather event ends, and your system will return to its normal behavior afterward. 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 better prepare yourself for everyday weather events or other grid instability, visit your utility provider’s website for updates. If your system has been affected by a natural disaster, learn more about what to do following a force majeure event.
