4.3 Power on
Double check all the power cables, communication cables, and
DIP switches
to make sure proper connections / settings.
Turn on the
power switch
; the battery will start self-detection process.
After self-detection process completed, if no fault is found, the SOC LEDs will light on sequentially.
Attention
·
To avoid current pulse of the inverter add on the battery bank. Shall start inverter first or switch on breaker between battery
and inverter after all connected batteries turned on.
·
A DC breaker should be installed between battery bank and inverter for safety issue.
·
All installation operation must follow local electric standard.
·
The battery has a built-in battery management system (BMS). Usage beyond the operating voltage range will damage the BMS
and may cause the loss of safety protection function. Multiple batteries can only be grouped in parallel, not in serial connections.
5. Trouble shooting
5.1 Upon start, please make sure:
1) Whether the battery can be turned on or not;
2) If battery is turned on, check the red light is off, flashing or lighting;
3) If the red light is off, check whether the battery can be charged/discharged ornot

5.2 Basic steps:
1) The battery cannot be powered on:
If the battery’s power switch has been turned on but no LED indicator is on or flashing, and the external power supply voltage
is above 57.6V, please contact the dealer.
2) The battery has been powered on and the red ALM indicator turns on. The battery is under abnormal status, please check
the following values:
A) Temperature:
If ambient temperature is above 50
℃
or below -10
℃
, the battery cannot work. Solution: make sure ambient temperature is
within the operating temperature range. Recommended operating temperature 0
℃
~35
℃
B) Current:
If charging current is over 55A or the discharge current is over 70A, battery’s self- protection function will be activated.
Solution: Check whether the current is too large, if it is too large, change the settings on the power supply side.
C) Over-Voltage:
When the charging voltage exceeds 58V, the battery’s self -protection will be activated. Solution: Adjust the charging voltage
of the power supply device.
D) Low voltage:
When the battery is discharged to 43.2V or lower, the battery’s self -protection will be activated.
Solution: Charge the battery until the red light turns off.
If the above measures have been taken but problem still exists, please switch off the battery and contact your dealer for help.
5.3 Advanced steps:
1)
Unable to charge the battery: Switch off the battery, disconnect the power cables from external power device, measure the
output voltage of the power device.
·
If the voltage is within 53 ~ 54V, reconnect the power cables and switch on the battery again.
·
If the problem still exists, please switch off the battery and contact yourdealer.
2) Unable to discharge the battery:
Disconnect the power cables and measure the battery voltage.
·
If the voltage is lower than 44.5V, please charge the battery until the voltage reaches above 48V;
·
If the battery voltage is over 48V and it still cannot be discharged, please switch off the battery and contact the dealer.
6. Emergencies
1) Leaking Batteries
If a battery leaks, avoid contact with the leaking liquid or gas. In case if anyone has been exposed to the leakage substances,
please follow the below instructions accordingly:
·
Inhalation: Evacuate from the contaminated area, and seek for medicalattention.
Contact with eyes: Rinse eyes with flowing water for 15 minutes, and seek for medical attention.
·
Contact with skin: Wash the affected area thoroughly with soap and water, and seek for medical attention.
