Bus-voltage too
low
Bus-voltage is 20V lower
than standard Bus-voltage
Check the open-circuit voltages of the strings and make sure it is
below the maximum DC input voltage of the inverter. If the input
voltage lies within the permissible range while the fault occurs,
please contact the service.
17
DRM S9 Error

21
BMS
Communication
Error
Battery BMS communication
interrupted
Check the connection of BMS cable with storage inverter. If the
BMS cable is connected normally while this fault occurs, please
contact the service.
22
CT Null Error
Current transducer not
connected
Check the connection of CT device. If the CT device is connected
normally while this fault occurs, please contact the service.
23
