4 Commissioning LED indicators The LED indicators on the front of the battery pack show its operational state as follows: LED Status Action Power on, Idle Charging Discharging Fault There are four LED indicators on the front of the battery packs to show its operating status. ON : This indicator stays on while the battery pack is ON.
CAUTION If it stays off, indicates FAULT or fails to operate, do not use the battery pack and contact LG Chem (page 34) or your distributor. Shutting off the battery pack To shut down the battery pack, take the following steps : 1.
5 Troubleshooting 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.
Troubleshooting 5.1.1 Post-Installation Check List Visual check if the wiring matches with the installation manual. (3.2 Cable connection) The disconnect switch is ON. The Circuit Breaker is ON. The battery "ON" LED is ON. The inverter power is ON. The inverter has the latest firmware. The inverter recognizes the battery.
Page 31
Troubleshooting If the battery LED is ON, but the battery is not charging or discharging 1. Update both the inverter and battery firmware version. Refer to the inverter's troubleshooting guide for instruction. 2. Check the inverter's setting for battery. Refer to the inverter's troubleshooting guide for the battery set-up instruction. 3.
