Commissioning

There are seven LED indicators on the front of the battery packs to show its operating status.
– Running LED indication
After start-up, the running indicator light flashes, which indicates that the equipment is in normal operation.
– Alarm LED indication
When the battery is in normal operation, the alarm LED is off, and after the fault occurs, the alarm LED is always on.
– SOC LED indication

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 the battery into pack or maintenance.

• 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. Regularly check whether the service environment of the battery meets the requirements and the installation position should be far away from the heat source.

2. In case of one of the following situations, it needs to be charged in time:
   – The battery is often undercharged;
   – The battery has been out of the use or stored for more than 3 months.

3. Regularly check whether the battery and its supporting terminals, connecting cables, and indicator lights are normal.

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 trouble-shooting 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 box 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 switches on and POWER 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 the inverter is well connected. If the connection is good, please replace an 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.
