Installation Guide
EEPROM
Transition disturbance while data is being written or read from EEPROM.
The data is not relevant for safe operation
The disturbance 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 Serviceline.
EeRestore
One of the duplicate data sets in the EEPROM is defective and has been
reconstructed without loss of data.
• The error message only serves to inform you and has no effect on
the performance of the inverter.
Fac-Bfr
Fac-Srr
FacFast
The grid frequency is no longer within the permissible range ("Bfr" or "Srr"
is an internal message of no relevance for the user).
For safety reasons, the inverter disconnects itself from the grid.
Corrective measures
• Check the grid connection and contact the utility operator if
necessary
• If the grid frequency is within the tolerance range, yet "Fac-Bfr",
"Fac-Srr" or "FacFast" faults are still being displayed, contact the
SMA Serviceline.
Imax
overcurrent
Overcurrent on the AC side. This fault code is displayed if the current in
the AC grid is larger than specified.
Corrective measures
• Check the system design and grid conditions.
K1-Close
K1-Open
Fault during relay test.
Corrective measures
• Contact the SMA Serviceline if this problem occurs often or several
times in succession.
MSD-FAC
MSD-VAC
MSD-Timeout
Internal measurement comparison fault or hardware defect.
Corrective measures
• If this fault occurs often, contact the SMA Serviceline.
Offset
The "Offset" operating condition is a normal operating condition that
occurs prior to grid monitoring. If "Offset" is displayed as an error, then
there is a disturbance in the data logging.
Corrective measures
• If this fault occurs often, contact the SMA Serviceline.
