Storm Guard

Storm Guard -- Battery Reserve Mode Active

Storm Guard is active, holding a configured minimum reserve charge in anticipation of a grid outage. This is normal operation displayed as a mode indicator in Enlighten.

Storm Guard triggered by weather forecast integrationManually configured Storm Guard reserve level
STEP 1
This is not a fault. Storm Guard holds the configured reserve and limits normal discharge. Check Enlighten app to see the current Storm Guard threshold and expected event window
STEP 2
If Storm Guard is triggering too frequently and limiting self-consumption, adjust the sensitivity settings or threshold in the Enphase app Battery settings
Storm Guard is active but no weather event was forecast and it was not manually set -- check and disable Storm Guard in Enphase app if not required
