My Sonnen battery is showing a red light

Updated

The status LED light, also known as the “eye,” on your Sonnen battery system is glowing red.

Cause

When the status LED light or “eye” on your Sonnen battery glows red, it typically indicates a fault condition that prevents normal operation or could potentially cause damage to the system.

Solution

Restarting your system can often resolve the issue. If not, please contact ServiceX support.

Follow these steps to restart the system:

  1. Turn off the battery system:
    1. Press the black S1 button (if your unit has an S1).
    2. Pull the F1 fuse towards you. The F1 fuse is located on top of the battery box on the right-hand side.
