• The battery module should be stored in an environment with a temperature range between -20℃-
  + 55℃, 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.

Storage environment temperature	Relative humidity of the storage environment	Storage time	SOC
Below -20℃	/	Not allowed	/
-20~35℃	5%~70%	≤ 6 months	20%≤SOC≤60%
35~55℃	5%~70%	≤ 3 months	20%≤SOC≤60%
Above 55℃	/	Not allowed	/

NOTICE

Damage to the system due to under voltages

• 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℃.
• 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 CS 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, CS 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 CM on;
3. Whether the battery system can be communicated with inverter;
4. Whether the battery can be output voltage or not.
5. Preliminary determination steps
