Automatically charge ahead of severe weather

Enphase EV charger plugged in to a car

Storm Guard is an Enphase app feature that monitors severe weather-condition alerts issued by the National Weather Service (NWS). If a severe weather alert is active in your locality, it prioritizes EV (Electric Vehicle) charging and energy storage to protect you from weather-related grid outages. This feature applies to all Enphase system users, including standalone IQ EV Chargers and Enphase Home Energy Systems. The Storm Guard feature can be used from the Enphase app.  

The Storm Guard feature can be in one of the following two states: 

  • Enabled:  When enabled, the Storm Guard feature monitors severe weather-condition alerts issued by the National Weather Service (NWS). If NWS issues a warning for your area, Storm Guard will override your system profile (if applicable) to initiate charging for your EV and home battery (if available), ensuring you are prepared for a potential grid outage. 

  • Disabled: In this state, weather alerts are not monitored for your area. If there is an active alert, you may face a blackout due to weather-related grid outages. Therefore, keeping the Storm Guard feature enabled is recommended as it allows your power to remain on despite such outages. 

By default, your system has Storm Guard enabled to ensure a reliable home energy backup system during a storm. 

How to enable/disable the Storm Guard feature

What happens when the Storm Guard feature is enabled and there is an active alert? 

If NWS issues a weather alert for your area, ‘Storm Alert: On’ is displayed under ‘Profile’ on the Status and Live Status pages. Your EV and home batteries will charge from solar as a first choice, and the grid is used as a second choice until the storm alert is on for your system. 

When the alert ends, your profile returns to its previous settings.
