EEPROM
Transition disturbance during reading or writing of EEPROM data. This
data is not essential 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
• Please contact your installer or the SMA Solar Technology
Serviceline.
EeRestore
One of the duplicate data sets in the EEPROM is defective and has been
reconstructed without loss of data.
• This error message is for information purposes only 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 with no relevance for the user). For safety reasons,
the Sunny Boy / Sunny Mini Central disconnects itself from the grid.
Corrective measures
• Please contact your installer to deal with the fault.
• If the grid frequency is within the tolerance range, yet "Fac-Bfr,"
"Fac-Srr" or "FacFast" faults are still being displayed, please contact
the SMA Solar Technology Serviceline.
HW-Signal
Internal measurement fault or hardware defect.
Corrective measures
• Please contact your installer or the SMA Solar Technology
Serviceline if this problem recurs.
Iac-DC_Offs-Srr
The DC component of the electricity being fed into the grid has exceeded
the permissible range. For safety reasons, the inverter disconnects itself
from the grid.
Corrective measures
• If the grid current is outside the permissible range due to local grid
conditions, contact the local utility operator for assistance.
• If the grid current is within the tolerance range, yet the "Iac-
DC_Offs-Srr" fault is still being displayed, please contact the SMA
Solar Technology Serviceline.
IGBTs
The internal hardware monitoring system has detected a fault in the
power electronics.
Corrective measures
• Please contact your installer or the SMA Solar Technology
Serviceline.
