Switch ON / OFF

a).Switch on: press On/Off button to switch on the battery, then the battery will do self-inspection beforeen able output.The LED will show the soc.
b).Switch off: press and hold On/Off button, the battery will shut down directly.
Please refer to “2.3” of this manual for the description off communication port and LED indication.

Trouble Shooting (Take 51.2V series products as an example)

1. Problem determination based on
2. Whether the battery can be turned on or not.
3. If battery is turned on, check the red light is off, flashing or lighting.
4. If the red light is off, check whether the battery can be charged / discharged or not.

Possible conditions:

1. Battery cannot turn on, switch ON and press the metal SW the lights are all no lighting or flashing.

2. Capacity too low, or module over discharged.
   solution: use a charge or inverter to provide 57.6-58.4V voltage.
   a. If battery can start, then keep charge the module and use monitor tools to check the battery log.
   b. If battery terminal voltage is <40Vdc, please use <0.05C to slowly charge the module to avoid affect to SOH.
   c. If battery terminal voltage is >40Vdc, it can use <0.5C to charge.
   d. If battery cannot start, turn off battery and repair.

3. The battery can turn on, but red light is lighting, and cannot charge or discharge. If the red light is lighting, that means system is abnormal, please check values as following.

4. Temperature: Above 60 °C or under -10 °C, the battery could not work.
   Solution: to move battery to the normal operating temperature range between 0°C and 50°C.

5. Current: If current exceeds 110A, battery protection will turn on.
   Solution: Check whether current is too large or not, if it is, change the settings on power supply side.

6. High Voltage: If charging voltage above 58.4V, battery protection will turn on.
   Solution: Check whether voltage is too high or not, if it is, to change the settings on power supply side. And discharge the module.

7. Low Voltage: When the battery discharges to 40V or less, battery protection will turn on.
   Solution: Charge the battery till the red light turns off.
   Cell voltage high. The module voltage is lower than 44V, SOC LED does not all on. When discharge the module protection disappear.
   Solution: keep charge the module by 57.6-58.4V or keep the system cycle. The BMS can balance the cell during cycling.

8. Unable to charge and discharge with red LED on. The temperature is 0~50 degree. Use charger to charge, not possible. Use load to discharge, not possible.

9. Under permanent protection. The single cell voltage has been higher than3.8 or lower than 2.0 or temperature higher than 80 degree.
   Solution: Switch off the module and contact your local distributor for repair.

10. Fuse broken.
    Solution: Switch off the module and contact your local distributor for repair.

11. Buzzer rings.

12. Reverse connection of cables.
    Solution: Power off all battery and inverters. Disconnect breaker. Check the cable connection and disconnect all power cables. Check the power port damaged or not.then try turn on the single module, without any cable connected. If no alarm, then it is reverse connection of cables. Switch off the module and contact your local distributor.

13. MOSFAIL.
    Solution: Power off all battery and inverters. Disconnect breaker. Check the cable connection and disconnect all power cables. Check the power port damaged or not. then try turn on the single module, without any cable connected. If still buzzer rings. Then it is mosfail. Switch off the module and contact your local distributor.

14. After switch On, the module turns on directly

15. BMS failure.
    Solution: Switch off the module and contact your local distributor.

Excluding the points above, if the faulty is still cannot be located, turn off battery and repair.

Emergency Situations

1. Leaking Batteries
   If the battery pack leaks electrolyte, avoid contact with the leaking liquid or
   gas. If one is exposed to the leaked substance, immediately perform the
   actions described below.

2. Inhalation: Evacuate the contaminated area and seek medical attention.

3. Contact with eyes: Rinse eyes with flowing water for 15 minutes and seek medical attention.

4. Contact with skin: Wash the affected area thoroughly with soap and water and seek medical attention.

5. Ingestion: Induce vomiting and seek medical attention.

6. Fire
   NO WATER! Only dry powder fire or carbon dioxide extinguisher can be used; if possible, move the battery pack to a safe area before it catches fire.

7. Wet Batteries
   If the battery pack is wet or submerged in water, do not let people access it, and then contact dealer for technical support. Cut off all power switch on inverter side.

8. Damaged Batteries
   Damaged batteries are dangerous and must be handled with the utmost care. They are not fit for use and may pose a danger to people or property.
   If the battery pack seems to be damaged, pack it in its original container, and then return it to dealer.

Remarks

Recycle and disposal
In case a battery (normal condition or damaged) needs disposal or needs recycling, it shall follow the local recycling regulation (i.e. Regulation (EC) N° 1013/2006 among European Union) to process, and using the best available techniques to achieve a relevant recycling efficiency.

Maintenance

1. 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%
2. 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.
3. 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%
