5 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 tem-

perature, 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 warn-

ing. 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 opera-

tion.

NOTE

For a serious warning, if no proper corrective actions are taken by the in-

verter, the battery pack’s circuit breaker automatically trips to protect itself.
