Troubleshooting

5.1 Troubleshooting Overview

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 Over discharge 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 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 or your distributor immediately.

CAUTION
Parallel battery system can only be applied between products of the same energy.

7.1.1 Setting for communication termination resistor (About Section B)

When you install the pack as primary, Turn ON the DIP switch for communication termination resistor.
When you install the pack as secondary, Turn OFF the DIP switch for communication termination resistor.

1. Case 1 : When installing one battery pack, Turn ON the DIP switch for communication termination resistor.
   (It is ON when switches are lowered.)

2. Case 2-1 : When installing two battery packs, and inverter has two communication ports separately for each battery pack, Turn ON the all DIP switches for communication termination resistor of both packs.

3. Case 2-2 : When you install the two battery packs and inverter has only one communication port for both battery packs, Install the secondary pack with the termination
   side. Install the primary pack with the termination resistor turned on in the last side. Middle side means that it is connected two number of communication pairs, (1st: from inverter to Secondary pack, 2 Nd: from Secondary pack to Primary pack),

Last side means that it is connected one communication pair (from Secondary pack to Primary pack) In Case 2-2, Communication cable is connected by daisy chain. Communication line from inverter should be connected secondary battery pack. And the additional communication line is connected from secondary battery pack to Primary battery pack. Secondary communication battery pack. 2nd line is connected between Primary and secondary. If installed incorrectly, the battery pack will not operate normally.

In the case of products using a combiner box, communication lines can also be connected through the combiner box.
The communication termination resistor can be changed depending on the inverter model, not the battery’s own condition. Therefore, you must refer to the battery communication connection description in the inverter installation guide. Below are some examples according to the inverter model.
