TROUBLE-LED-ABNORMALRed/Green LED flashing or abnormal indication (alarm or protection).Warning
Description

Per 10.2 Troubleshooting: when the red/green LED on the panel is flashing or normally on it may be just an alarm or protection. Check the 'LED fault message' in chapter 7 for detailed fault-shooting steps. Generally the alarm indication is normal without manual intervention; when the alarm trigger state is removed, the battery system automatically returns to normal use.

Recommended fix

Check whether the red light on the LPBA48100-OL is on; whether the battery can be output voltage or not. Refer to the 'LED fault message' table for detailed fault-shooting steps. The system normally clears the alarm automatically once the trigger condition is removed.
