7. TROUBLESHOOTING
PROBLEM IDENTIFICATION
1)
Can the battery be switched on or not?
2)
When the battery is on, check if the red light is off, flashing or lit.
3)
When the red light is off, check whether the battery can be charged/discharged.
ACTIONS
1)
Battery module does not switch on and the LED's do not react when switched on, although:
•
The device switch is switched on
•
The Run LED flashes
•
The external charging voltage 48VDC
In this case you should contact your supplier.
2)
The battery module can be switched on, but the red light is on. The battery module cannot be charged or
discharged. If the red light is on, i.e. the system is not running normally, please check the values as follows:
a. Temperature: Above 50°C or below -10°C, battery not working.
Solution: Get the battery into the normal operating temperature range between 0°C and 50°C.
b. Current: If the current is greater than 100A, the battery protection will turn on.
Solution: Check if the charge/discharge current is okay. If it is, check the RS485 communication,
otherwise change the inverter settings.
c. Overvoltage: If the charging voltage is above 54V, the battery protection will turn on.
Solution: Check if the voltage is too high or not, if this is the case check RS485 communication,
otherwise change the inverter settings.
d. Undervoltage: If the battery module has discharged to 44.5V or less, the battery protection will turn on.
Solution: Charge the battery module for some time until the red light goes out.
If the error still cannot be located, turn off the battery module and have it checked.
3)
The battery cannot be charged or discharged.
a.
Cannot be charged:
Disconnect the power cables, measure the charging voltage. If the voltage is 53~54V, restart the
battery, connect the power cable and try again. If it does not work yet, turn off the battery and contact
your supplier.
b.
Cannot be discharged:
Disconnect the power cables and measure the voltage on the battery side. If it is below 44.5V, please
recharge the battery. If the voltage is above 48V and still cannot discharged, turn off the battery and
contact your supplier.
