38 DC input O/V
DC input voltage is higher than the upper
limit. After faults are recovered, the inverter
will restart automatically.
1. Set the inverter power to discharge
power to discharge the battery and
decrease the battery voltage
2. Check if the charging voltage, float
voltage and battery voltage upper limit are
reasonable
If the fault occurs repeatedly, please
contact Sinexcel Electric Customer Service
Center.
39 DC L/V
DC input voltage is lower than the lower
limit. After faults are recovered, the inverter
will restart automatically.
1. Check whether the battery is normally
connected to the inverter
2. Set the inverter power to charge
direction, charge the battery and increase
the battery voltage
3. Check if the EOD voltage setting is
reasonable
If the fault persists, please contact Sinexcel

3B BMS fault
BMS sets fault flag and requires inverter
shutdown
Check the BMS fault flag to find out the
cause of the BMS alarm. After the BMS
clears the fault flag, the fault is cleared
automatically.
3C BMS TimeOut Inverter loses communication with BMS
1. Check whether the communication cable
between the inverter and BMS is firmly
connected
2. If the inverter does not need to
communicate with the BMS, set the BMS
timeout to 0
3D EMS TimeOut Inverter loses communication with EMS
1. Check whether the communication cable
between the inverter and EMS is firmly
connected
2. If the inverter does not need to
communicate with the EMS, set the BMS
timeout to 0
40 DC soft start F Fail in the process of DC soft start.
If the fault occurs repeatedly, please
