Over Temp Derating
The inverter has de-rated
because of the temperature
is too high
Ensure the installation position and installation
method meet the requirements of Section 3.4 of this
user manual.
Check whether the ambient temperature of the
installation position exceeds the upper limit. If yes,
improve ventilation to decrease the temperature.
Check whether the ID90~ID92 fault (fan fault) exist,
if yes, please replace the corresponding fan.
ID82
Over Freq Derating
The inverter has de-
rated because of the
grid frequency too hig
The inverter automatically reduce the output power
when the frequency of electrical grid is too high.
ID83
Remote Derating
The inverter has de-rated by
the Remote control
The inverter records ID83 in case of remote power
derating operation. Check the wiring of remote input
and output control signal port on the communication
board according to Section 4.4 of this user manual.
ID84
RemoteOff
The inverter has shut down
because by the Remote
control
The inverter records ID84 in case of remote shutdown
operation. Check the wiring of remote input and
output control signal port on the communication board
according to Section 4.4 of this user manual.
ID85
Underfrequency Derating
The inverter has derated
because of grid frequency
too low
The inverter automatically reduces the output
power when the frequency of electrical grid is too low
ID86
Fan4 alarm
The fan4 is fault
Check whether the internal fan is not working, if so,
replace the fan, if the alarm still exits after the
replacement, please contact the technical support.
ID25
Bus UVP
The bus voltage Is too low
If the PV array configuration is correct (no ID5 fault),
the possible cause is that the solar irradiance is too
low. The inverter automatically returns to normal
operating status after the solar irradiance returns to
normal level.
ID26
Bus OVP
The bus voltage Is too high
ID26-ID27 are internal faults of The inverter, turn
OFF the “DC switch”, wait for 5 minutes, then turn
ON the “DC switch”. Check whether the fault is
rectified. If no, please contact The technical support.
ID27
V bus Unbalance
The bus voltage is not
balanced
ID28
Dci OCP
The Dci is too high
Check the input mode (parallel mode/ independent
mode) setting of The inverter according to Section
4.5 of this user manual.
If the input mode is correct, turn OFF the “DC
switch”, wait for 5 minutes, then turn ON the “DC
switch”. Check whether the fault is rectified. If no,
please contact The technical support.
ID29
SwOCPInstant
The grid current is too high
Internal faults of The inverter, turn OFF the “DC
switch”, wait for 5 minutes, then turn ON the “DC
switch”. Check whether the fault is rectified. If no,
please contact the technical support.
ID30
SwBOCPInstant
Ihe input current is too high
Check whether the input current is higher than the
maximum input current of the inverters, then check
the input wiring, if both are correct, please contact The
technical support.
