System Alerts and Notifications

You may receive push notifications and/or alerts in your Tesla app when your system experiences issues that may require basic troubleshooting, or when your Powerwall changes status such as Going Off-Grid or when Storm Watch activates. Your phone and Tesla energy products must be connected to the internet to receive push notifications and alerts.

Note: 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. Additionally, features for certain events may not be available in your country.

Learn more about the following events and their expected push events.

Off-Grid and Grid Outages

Grid Outage

• A grid outage has occurred, and Powerwall is discharging to power your home.
• Powerwall will disconnect your home from the grid if there are disruptions to the voltage or frequency of the grid, such as an outage or brownout.
• Powerwall may discharge below your set Backup Reserve.
• Reduce your home loads to extend your backup duration while off-grid.

Low Energy While Off-Grid

• Powerwall energy is very low, and you will have limited backup time remaining.
• Immediately reduce your home’s power use to extend backup duration, or Powerwall may fully discharge during this outage.

Grid Reconnected

• Grid power has returned.
• Powerwall will continue normal operation. If Powerwall discharged below your Backup Reserve during an outage, it will prioritize charging from solar or grid to meet your set reserve before resuming Self-Powered or Time-Based Control behavior.

Go Off-Grid

• Powerwall disconnected from the grid through Go Off-Grid. 

Storm Watch

• Storm Watch event has begun, and Powerwall will prioritize charging to maximize your backup protection.
• The notification text is customized for the storm type in your area, if available.

Low Energy and High Loads

Waiting for Solar

• Powerwall is too low on energy and has stopped powering your home.
• Powerwall will resume charging once enough solar has become available.
• During an extended outage, Powerwall will conduct hourly checks for power until enough solar power is available to simultaneously power your home and charge Powerwall.
• After receiving this notification, you may manually restart your Powerwall by toggling the on/off switch on the right side.

Waiting for User Input

• This is sent following the 'Waiting for Solar' push notification.
• Powerwall is unable to generate enough solar to power your home and resume charging.
• After receiving this notification, manually restart your Powerwall by toggling the on/off switch on the right side.

Waiting for Grid

• This is sent following the 'Waiting for User Input' push notification.
• Powerwall is empty and unable to resume power until the grid returns.

Powerwall Overloaded

• During a grid outage, Powerwall attempts to power your home, but your home requires more power than is available.
• Turn off high-power items to help Powerwall resume powering your home.

System Issues

Breaker Open

• The AC breaker to connect your Powerwall to your home is off and needs to be switched back on.

Calibration in Progress

• Powerwall must periodically undergo routine calibration for optimal battery performance.
• Calibration may take up to 24 hours.
• Powerwall may discharge past your backup reserve.
• Powerwall may not charge from solar.
• Powerwall is still ready to back up your home during grid outages.

Side Switch Off

• The side switch on your Powerwall is switched off and Powerwall will not power your home.
• Solar may still generate if you have a Powerwall 2.
• If you are not expecting this, toggle the switch on the right side of your Powerwall 2.

Solar Production Limited

• One of your inverters may not be producing solar due to a fault detected with your solar system.
• Contact your installer to schedule a site visit.

Powerwall Disabled

• One or more Powerwall operations has been disabled due to an internal fault that requires replacement.
• Turn off the Powerwall enable switch and contact your installer to schedule a replacement.

Rapid Shutdown Device Off

• The rapid shutdown device is switched off and Powerwall will not power your home. Solar may still generate depending on your system configuration.
• A rapid shutdown device may look like a red emergency stop button, or a separate on/off switch near your Powerwall or solar inverter.
• If you are not expecting this, you may contact your installer to confirm whether this is expected or if a scheduled service visit is required.

Virtual Power Plant

Event Scheduled

• We have scheduled your Powerwall to participate in a virtual power plant (VPP) event.
• After this push notification is sent, your Powerwall may pre-charge from solar to prepare for discharge.

Event Beginning

• This push notification is sent at the beginning of a VPP event, when your Powerwall starts discharging to support the grid.
