Installation Manual
Derating
The "Derating" operating state is a normal operating state which may
occur occasionally and can have several causes.
Once the inverter enters the "Derating" operating state, it will display the
"Derating" warning until the next complete disconnection of the device
(at the end of the day).
Corrective measures
• Check the heat dissipation as described in Section 8.2 "Checking
EEPROM
Transition disturbance while data is being written or read from EEPROM.
The data is not relevant for safe operation.
• This disturbance has no effect on the performance of the inverter.
EEPROM dBh
EEPROM data is defective, the inverter has switched off because the loss
of data has disabled important functions of the inverter.
Corrective measures
• Contact 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 mains frequency is no longer within the permissible range
("Bfr"/"Srr"/"Fast" is an internal message that has no meaning for the
user). The inverter disconnects from the electricity grid for safety reasons.
Corrective measures
• Check the grid connection and contact the network operator if
necessary.
• If the mains frequency is within the tolerable range, but "Fac-Bfr",
"Fac-Srr"or "FacFast" faults are still displayed, contact the
SMA Service Line.
K1-Close
K1-Open
Error during relay test.
Corrective measures
• Contact the SMA Service Line if this disturbance occurs frequently
or several times in a row.
Imax
Overcurrent on the AC side. This message is displayed if the current in the
AC electricity grid is higher than specified.
Corrective measures
• Check the plant design and grid conditions.
