EEPROM Transition fault while data is being written or read from EEPROM. The
data is not relevant for safe operation.
This fault has no effect on the performance of the inverter.
EEPROM dBh EEPROM data is defective, the device has switched off because the loss
of data has disabled important functions of the inverter.
Corrective measures
• Contact the SMA Service Line.
EeRestore One of the duplicate records in the EEPROM is defective and has been
reconstructed without loss of data.
• This error message only serves to inform you and has no effect on
the performance of the inverter.
Fac-Bfr
Fac-Srr
FacFast The power frequency is no longer within the permissible range
("Bfr" or "Srr" is an internal message of no relevance for the user).
The inverter disconnects itself from the power distribution mains for safety
reasons.
Corrective measures
• Check the mains connection and contact the network operator if
necessary.
• If the power frequency is within the tolerable range, but "Fac-Bfr",
"Fac-Srr"or "FacFast" faults are still displayed, contact the
SMA Service Line.
Imax Overcurrent on the AC side. This message is displayed if the current in the
AC mains is higher than specified.
Corrective measures
• Check the plant design and mains conditions.
K1-Close
K1-Open Error during relay test
Corrective measures
• If this fault frequently occurs or occurs several times consecutively,
contact the SMA Service Line.
MSD-Fac
MSD-Vac
MSD-Timeout Internal measurement comparison fault or hardware defect.
Corrective measures
• If this fault occurs frequently, contact the SMA Service Line.
offset The "offset" operating state is a normal operating state that occurs prior
to mains monitoring. If "offset" is displayed as an error, there is a fault in
the data logging.
Corrective measures
• If this fault occurs frequently, contact the SMA Service Line.
