as outdoors. However, if installed outdoors, do not allow the battery pack to be
exposed to direct sunlight or water sources, as they may cause:
- Power limitation phenomena in the battery (with a resulting decrease in energy
production by the system).
- Premature wear of the electrical/electromechanical and mechanical components.
- Reduction in performance, performance warranty and possible damage of the battery
Do not connect any AC conductors or photovoltaic conductors directly to the
battery pack. These are only to be connected to the inverter.
1.2.3 Response to Emergency Situations
The Product includes internal fault mechanisms designed to prevent failures and subsequent
risk hazards. However, LG Electronics cannot guarantee safety performance of the Product is
ever exposed to abuse, damage or negligence.
If a user happens to be exposed to the internal materials of the battery cell due to
damage on the outer casing, the following actions are recommended.
In case of inhalation: Leave the contaminated area immediately and seek medical
attention.
In case of contact with eyes: Rinse eyes with running water for 15 minutes and
seek medical attention.
In case of contact with skin: Wash the contacted area with soap thoroughly and
seek medical attention.
In case of ingestion: Induce vomiting and seek medical attention.

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 warning state. Fault1 is blinking. Fault 2 is continuous. See
Section 5 Troubleshooting guide for detail condition.
6. Power saving : Battery stay in minimum self consumption power mode.
7. FW update : Battery is in update sequence. See the detail LED indication about

5. Close the front cover.
5 Troubleshooting
Check the LED indicators on the front to determine the state of the battery pack. A fault 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 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
The fault state is cleared when the battery pack resumes normal operation. If battery pack is not

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
Electronics regional contact point or your distributor immediately.
