5.1 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 qualied
personnel, Installer or LGC regional contact point.
NOTE
For a serious warning, if no proper corrective actions are taken by the inverter, the
battery pack’s circuit breaker automatically trips to protect itself.
CAUTION
If the battery pack or the inverter indicates FAULT or fails to operate, contact LGC
regional contact point(page 35 ) or your distributor immediately.
