Troubleshooting
Check the indicators on the front to determine the state of the battery pack. A warning
state is triggered when a condition, such as with voltage or temperature, is beyond design
limitations. The battery pack’s BMS periodically reports its operating state to the inverter.
When the battery pack falls outside prescribed limits, it enters a warning state.
When a warning is reported, the inverter immediately stops operation.
Use the monitoring software on the inverter to identify what caused the warning.
The possible warning messages are as follows:
•
Battery Over Voltage
•
Battery Under Voltage
•
Battery Over Temperature
•
Battery Under Temperature
•
Battery Discharge Over Current
•
Battery Charge Over Current
•
BMS Internal Communication
•
Battery Cell Voltage Imbalance
The abnormal state is cleared when the battery pack recovers normal operation.
If battery pack is not working correctly and the issue persists, contact a qualified
personnel, Installer or LGC regional contact point.
