E054
Communication
loss with
Communication
Board
Wiring box is not communicating
with the inverter.
Check memory card on communication board. Check
all conductors on communication board are properly
connected. Run the “Accept new board” program
through the service menu. Contact ABB technical
support for advanced password and/or if problem
persists.
E055
Arc Fault wrong
cong.
AFD conguration is incorrect. Check that the AFD cables are properly connected.
Otherwise, this may be an internal error and ABB
technical support is needed.
E056
Over Temp.
(Over temperature
from external box)
Excessive temperature
measured inside the inverter’s
wiring box (high internal
temperature). This error relates
to the temperature measured on
external boxes.
Check that the inverter is not exposed to direct
sunlight. If in direct sunlight, order and install an ABB
sun shield or create sufcient shade by other means
while maintaining airow around the inverter. Wait for
the temperatures to which the inverter is exposed to
return to the operating range and for the inverter to
cool down.
If the problem persists (once the ambient temperature
has returned to the range), contact ABB technical
support.
E057
Vbulk reading error
(Error if Vin is >
Vbulk +1OV)
Input voltage (Vin) higher than
booster voltage (Vbulk). The
error occurs if the input voltage
exceeds the bulk voltage
(voltage on the DC-DC circuit
inside the inverter).
Measure the input voltage inside the inverter with a
voltmeter. If it is higher than the maximum voltage of
the operating range, it is necessary to check the PV
array conguration.
If the voltage has also exceeded the maximum input
threshold, the inverter could be damaged.
If it is lower than the maximum voltage of the
operating range, the alarm is caused by an internal
malfunction and it is necessary to contact ABB
technical support.
E058
Pin vs. Pout check
error
(Error if Pout-Pin >
Pdelta
The error occurs if the difference
between the measured value of
input power and that of output
power is greater than the limit
imposed internally to the inverter.
Error inside the inverter that cannot be checked
externally. After switching the inverter off and then on
again, if the problem persists, contact ABB technical
support.
E077
Internal error
(System
conguration error)
Error inside the inverter. Error inside the inverter that cannot be checked
externally. After switching the inverter off and then on
again, if the problem persists, contact ABB technical
support.
