1 Introduction 1.1 Features The RESU® 6.4 EX battery pack has the following features: Photovoltaic system: This battery pack is designed for photovoltaic system compatibility. Battery management system (BMS): The battery pack’s built-in BMS monitors its operation and prevents the battery from operating outside design limitations. See Troubleshooting on page 11. Expandability: The battery capacity can be increased by adding expansion battery packs. Up to two expansion battery packs can be added.
Introduction Charge in progress : While the main pack is charging, the Charge / Dis- charge indicator is lit red. Discharge in progress : While the main pack is discharging, the Charge / Discharge indicator is lit green. Alarm : When the main pack is in a warning or fault state, the Status indicator alternately flashes green and orange. See Troubleshooting on page 11. Expansion battery pack RESU R 6.

3 Troubleshooting 3.1 Starting the Battery Pack Put the battery pack in operation by taking the following steps: 1. Make sure that the circuit breaker switch is in the OFF or Trip position. 2. Move the circuit breaker switch to the ON position to turn on the main battery pack. See if the battery pack is successfully initialized. • The Status indicator on the front should turn on in orange and then change to green in 7 seconds. If it stays orange, contact LG Chem or your distributor.
Troubleshooting 3.3 Main Battery Pack Check the indicators on the front to determine in what state the main battery pack is.
Troubleshooting • BMS Internal Communication • Battery Cell Voltage Imbalance An abnormal state is cleared when the main pack recovers its normal condition. NOTE For a serious fault, if no proper corrective actions are taken by the inverter, the main pack’s circuit breaker automatically trips to protect itself. For example, if the Status indicator stays orange for more than 5 minutes, the circuit breaker trips. Use the monitoring software on the inverter to identify what caused the fault. 3.
4 Emergency Situations The RESU 6.4 EX battery pack comprises multiple batteries that are designed to prevent hazards resulting from failures. However, LG Chem cannot guarantee their absolute safety. 4.1 Leaking Batteries If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas.
