Communication related problems
Unable to communicate with inverter on compatible list.
Possible conditions:
1) RS485: baud rate. Check the dip switch1, set to correct one, and restart.
2) CAN: pin definitions. Try to connect the CAN-H, L, GND only and do not
connect other pins to the inverter, using the correct cable.
Function related problems
1) Whether the battery can be turned on or not
2) If the battery is turned on, check that the red light is off, flashing or lighting
3) If the red light is off, check that the battery can be charged/discharged.
Possible conditions:
1) Battery cannot be turned on or switched ON. And the lights are all not
lighting or flashing when pressing the red SW.
a) Capacity too low, or module over discharged.
Solution: use a charger or inverter to provide 51.2~56.8 V voltage.
If the battery can be turned on, then keep charging the module and use
monitor tools to check the battery log.
Depending on the different battery terminal voltages, take the following 2
methods:
If the battery terminal voltage is ≤45 VDC, use ≤0.05 C to slowly charge
the module to avoid affecting SOH;
If battery terminal voltage is >45 VDC, use ≤0.5 C to charge.
If the battery cannot start, turn off and repair the battery.
2) The battery can be turned on, but red light is on, and the battery cannot
charge or discharge. If the red light is on, it means that system is abnormal.
Please check the following values:
b) Temperature: If the temperature is above 60°C or under -10°C, the battery
will not work.
Solution: move battery to the normal operating temperature range
between 0°C and 50°C.
