9. Troubleshooting and Maintenance
9.1 Maintenance
1) It is recommended that the battery storage time is not more than six 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 90%.
3) Every year after installation. The connection of power connector, grounding point, power cable and
screw are suggested to be checked. Make sure there is no loose, no broken, no corrosion at
connection point. Check the installation environment such as dust, water, insect etc. Make sure it is
suitable for IP21 battery system.
4) If the battery is stored for long time, it is required to charge them every six months, and the SOC
should be higher than 90%.
9.2 Troubleshooting
When the red / green LED on the panel is flashing or normally on, it does not mean that the FL5.2 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, FL5.2 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) Battery system cannot work, when DC switch on and POWER on, the LED doesn’t light up or flash,
please consider contact the local distributor.
2) The LED display of BMS is normal, but it cannot charge and discharge. Observe the display screen
of 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.
