6.1 Troubleshooting Overview
Check the LED indicators on the front to determine the state of the battery
pack. The battery enters into a fault state when certain conditions like
voltage or temperature are beyond designed limitations. The battery
pack’s BMS periodically reports its operating state to the inverter.
When the battery pack falls outside of prescribed limits, it enters into
fault state. When a fault is reported, the inverter immediately terminates
operation.
Use the monitoring software on the inverter to identify what caused the
fault state. The possible warning messages are as follows:
• Battery Overvoltage
• Battery Undervoltage
• Battery Over Temperature
• Battery Under Temperature
• Battery Discharge Overcurrent
• Battery Charge Overcurrent
• Battery Overcharge Power Limit
• Battery Overdischarge Power Limit
• BMS Internal Error
• External Communication Error
• Internal Communication Error
• Battery Cell Deviation Voltage
• Battery Pack Undervoltage
• Battery Urgent Undervoltage
