Red LED blinking

Red LED blinking — Low battery warning

SolarEdge · ESS Systems

Was bedeutet Red LED blinking ?

The red LED on the inverter/charger is blinking, indicating a low battery condition. This warning can occur in off-grid or backup systems, or when the battery is nearly depleted in self-consumption optimization systems.

Häufige Ursachen

  • Battery voltage is below the low DC voltage alarm threshold.
  • System is configured for off-grid or backup power.
  • Battery is discharging heavily and approaching its minimum state of charge.

  3. 3

    For email notifications, set 'Automatic alarm monitoring' to 'Only alarms' on the VRM Portal.
