Error
EEPROM
Transition failure during reading or writing of data EEPROM,
the data is not essential for safe operation - this failure does
not effect performance.
Error
EEPROM p
Data EEPROM defective, device is set to permanent disable
due to the fact that the data loss affects important functions of
the inverter. Contact SMA for assistance.
Error

Error
EarthCur-
Max-S
The earth current between PV+ and GND has exceeded the
maximum limit. Check the PV array for ground faults.
Error
EarthCur-
Max-B
The earth current between PV+ and GND has exceeded the
maximum limit. Check the PV array for ground faults.
Error
GFDI Fuse
Ope
The GFDI-Fuse is open or cleared. Check the PV array for
ground faults before replacing the fuse.
Error
Derating
The inverter is derating because of high temperature. Verify
that the fans are operating normally and that the intake
screens are clean. Check the intake vents for debris. Verify
that there is adequate ventilation around the inverter. This
condition may be normal in periods of high ambient temper-
atures (above 45°).
Error
XFMR_TEMP
_F
High transformer temperature. The inverter will remain
stopped until the transformer has cooled.
Error
XFMR_TEMP
_W
High transformer temperature is gone. The SB3800U starts
working and shows the failure “XFMR_TEMP_W“. Verify that
the fans are operating normally and that the intake screens
are clean. Check the intake vents for debris. Verify that there
is adequate ventilation around the inverter. This condition
may be normal in periods of high ambient temperatures
(above 45°).
