SMA Solar Technology AG Measurement Channels and Messages

User Manual SB_SMC-BEN092840 35

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.
