9. Troubleshooting and Maintenance
9.1 Maintenance
1) It is recommended that the battery storage time is not more than 6 months.
2) Regularly check whether the service environment of the battery meets the requirements, and the
installation position should be far away from the heat source.
3) The battery module should be stored in an environment with a temperature range between 0 ℃
-+35℃, and charged regularly according to the table below with no more than 0.5 C(A C-rate is a
measure of the rate at which a battery is discharged relative to its maximum capacity.) to the SOC of
50% after a long time of storage.

Charge the over-discharged system within seven days when the temperature is above 25℃.
Charge the over-discharged system within seven days when the temperature is below 25℃.
4) 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.
9.2 Troubleshooting
When the S LED on the panel is flashing or normally on, it does not mean that the battery is abnormal, it
may be just an alarm or protection. Please check the “Fault status indicated by indicator” 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, the battery 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 battery system can be communicated with inverter;
3) Whether the battery can be output voltage or not.
