Note: “1”indicates that the Dip switch is “ON”, “0” indicates that the Dip switch is “OFF”. And it also indicates the position of the Dip switch. For example, “0001 0000” indicates that the 4th Dip switch is “ON”，the rest are all “OFF”.

1. Please change the address switch in the right position accordingly base on the system battery quantity before power on battery.
2. After pressing the power switch for 1s, all LEDs will be on and flashing, which indicates that the battery is started normally. After pressing the start button for 3s, the battery will turn on the discharge function.

Commissioning

There are seven LED indicators on the front of the battery packs to show its operating status.
Fault status indicated by indicator:

• ● Off
• ○ On
• ◐ Flash

1. The RUN indicator blinks and the ALARM indicator is off: The battery is running.
2. RUN indicator Steady on: The device is powered off or the battery is faulty and cannot be charged or discharged.

Exclusion

The warranty shall not cover the defects caused by normal wear and tear, inadequate maintenance, handling, storage faulty repair, modifications to the battery or pack by a third party other than manufacturer or manufacturer agent, failure to observe the product specification provided herein or improper use or installation, including but not limited to the following.

• Damage during transport or storage.
• Incorrect Installation of battery into pack or maintenance.
• Use of battery pr pack in inappropriate environment.
• Improper, inadequate, or incorrect charge, discharge or production circuit other than stipulated herein.
• Incorrect use or inappropriate use.
• Insufficient ventilation.
• Ignoring applicable safety warnings and instructions.
• Altering or attempted repairs y unauthorized personnel.
• In case of force majeure (ex: lightning, storm, flood, fire, earthquake, etc.).
• There are no warranties implied or express other than those stipulated herein. the manufacturer shall not be liable for any consequential or indirect damages arising or in connection with the product specification, battery or pack.

Troubleshooting and Maintenance

Maintenance

1. It is recommended that the battery storage time is not more than 6 months.
2. It is required to charge the battery at least once every 6 months, for this charge maintenance make sure the SOC is charged to higher than 70%。 In the condition of 90% charging. It is recommended that the customers use a low-voltage inverter and fill the battery every half month, otherwise, the SOC will deviate.
3. Every year after installation. The connection of the power connector, grounding point, power cable, and screw are suggested to be checked. Make sure there is no loose, no broken, no corrosion at the connection point. Check the installation environment such as dust, water, insects etc. Make sure it is suitable for the IP21 battery system.

Troubleshooting

When the red/green LED on the panel is flashing or normally on, it does not mean that the LV5200 is abnormal, it may be just an alarm or protection. Please check the ‘LED status indicators’ in Chapter 7 for the detailed faulty definition before any troubleshooting steps. In general, the alarm indication is normal without manual intervention. When the alarm-triggering state is removed, LV5200 will automatically return to normal use.
Problem determination based on the following points

1. Whether the green light on the power switch is on;
2. Whether the buzzer in BMS is on;
3. Whether the battery system can be communicated with inverter;
4. Whether the battery can be output voltage or not.

Preliminary determination steps

1. The battery system cannot work, when DC is switched on and the POWER is on, the LED doesn’t light up or flash, please consider contacting the local distributor.
2. The LED display of BMS is normal, but it cannot charge and discharge. Observe the display screen of the inverter and there is no SOC. Please check whether the RS485 communication between BMS to inverter is well connected. If the connection is good, please replace a RS485 communication cable. If the SOC is still not visible on the inverter display screen, please contact the local distributor.
3. After the battery system is powered on, if you can see the alarm information on the LED and inverter display screen at the same time, please contact the local distributor.
