There are four LED indicators on the front of the battery packs to show its operating status.
1. Power On(Init) : Initialization for operating the battery
2. Ready : Battery is ready for operating normally.
3. Charge : Battery pack is charging.
4. Discharge :Battery pack is discharging.
5. Fault : Battery pack is in warning state. Fault1 is blinking. Fault 2 is continuous.
See Section 5 Troubleshooting guide for detail condition.
6. Power saving : Battery is in minimum self consumption power mode.
7. FW update : Battery is in update sequence. See the detail LED indication about
Updating, Update complete, Update failed.
4.2 Powering On the Battery Pack
Power on the battery through the following steps:
1. Open the front cover.
2. Ensure the circuit breaker switch is in the OFF position.
3. Turn on the circuit breaker.
4. Seconds after the circuit breaker switch is ON, four (4) LED indicators will light
up.

5 Troubleshooting
Check the LED indicators on the front to determine the state of the battery pack. A faulted state
is triggered when certain conditions like voltage or temperature are beyond design 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 a faulted state. When a fault is
reported, the inverter immediately terminates operation.
Use the monitoring software on the inverter to identify what caused the faulted 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
The faulted state is cleared when the battery pack resumes normal operation.
If battery pack is not working correctly and the issue persists, contact LG Energy Solution
regional contact service Point.
NOTE
For serious warnings, if no proper corrective action is taken by the inverter, the battery
pack's circuit breaker will automatically trip to protect itself.
CAUTION
If the battery pack or the inverter indicates FAULT or fails to operate, contact LG Energy
Solution regional contact point.

IF ANY ITEM IN #7 IS CHECKED AS "NO" OR IF THE INVERTER
NEEDS TO BE TURNED OFF, TURN OFF THE CIRCUIT
BREAKER.
