5. Trouble Shooting Steps
Please check the ‘LED Indicators Instructions’ table for the detailed faulty definition before any
trouble-shooting steps.
5.1 Problem determination
1) Whether the battery can be turned on or not;
2) If battery is turned on, check the red and yellow light is off, flashing or lighting, follow the
‘LED Indicators Instructions’ ;
3) If the red and yellow light is off, further check whether the battery can be charged/discharged.
5.2 Preliminary determination steps
1) Battery cannot turn on, switch on the lights are all no lighting or flashing.
Solution: Turn power switch ON, and then charge the battery with external power supply voltage 26V or
more, if the battery still unable to turn on, turn the power switch off and contact the installer.
2) The battery can be turned on but cannot charge or discharge. If the red/yellow light is lighting, that means
system is abnormal, please follow the ‘LED Indicators Instructions’ to check:
a) Over/Low temperature: Above 55
℃
or under -10
℃
, the battery could not work.
Solution: turn off the battery module, move battery to the normal operating temperature range between -
10
℃
and 55
℃
b) Over Current: If current is >100A, battery protection will turn on.
Solution: Check and change the settings on power supply or load side. And wait until battery release the
protection.
c) Short circuit/Reverse polarity: Check power cable and grounding cable connection whether is wrong or
missing. Check inverter/charger connected of a potential short circuit source.
d) High Voltage: If charging voltage above 28.5V, battery protection will turn on.
Solution: Check and change the settings on power supply side. And wait until battery release protection or
discharge the battery.
e) Low Voltage: When the battery discharges to 23.2V or less, battery protection will turn on.
Solution: Charge the battery by external charger, with voltage ≤28.5Vdc, current ≤55Amps.
f) Internal communication error: Check the internal communication wiring connection whether is wrong or
missing, then make a restart of the whole system.
g) Critical Failure
：
Both RED and YELLOW LEDs constant lighting.
Solution: Contact the distributor, need a replacement or repairment.
