Alarm Type Description Cause Solution
80 BROWNOUT
DERATING
The nominal power is not
available from the AC
Grid. The inverter could
compensate from DC
source.
AC in below 100V - reduce
power from the AC input and
pull power from the DC input
Check AC grid and
configuration
81 FAN LIFE
ELAPSED
Fan running time has exceeded preset value to advise fan
replacement
Replace FAN and reset the
counter time
82 REMOTE OFF Inverters are set to OFF
remotely
Inverter are switch OFF by
remote function
Replace FAN and actualize
the counter time
83 MANUALLY OFF The inverter are manually
set to OFF.
Inverter are switched OFF
by the OFF function in
Hyperterminal
Start inverter by REM ON/
OFF terminal
Start inverter through the
Hyperterminal
Status AC on Inverter
160 ACin OK The grid AC is coming back
inside the preset range
AC voltage coming back
inside the range
Nothing to do
161 Vac_in too low The input grid is below the
preset range
AC voltage outside the range Check AC grid and
configuration
162 Vac_in too high The input grid is upper the
preset range
AC voltage outside the range Check AC grid and
configuration
163 ACin IMP too
high
This status appears during
the starting procedure of the
ACinput stage
The module can stay in this
status if it can't start. This
happens if the power of the
AC supply is too low
164 STATUS 164
165 Vac_in too LOW The input grid is below the
preset range
AC voltage outside the range
(RMS value)
Check AC grid and
configuration
166 Vac_in too HIGH The input grid is above the
preset range
AC voltage outside the range
(RMS value)
Check AC grid and
configuration
167 ACin NOT
CONFORM
ACin is outside the range AC voltage outside the range
(instantaneous value)
Check AC grid and
configuration
168 ACin NOT
CONFORM
ACin is outside the range AC voltage outside the range
(instantaneous value)
Check AC grid and
configuration
169 ACin NOT
CONFORM
ACin is outside the range AC voltage outside the range
(instantaneous value)
Check AC grid and
configuration
170 STATUS 170
171 ACin NOT
CONFORM
ACin is outside the range AC voltage outside the range
(instantaneous value)
Check AC grid and
configuration
172 ACin THD too
high
THD grid is outside the
allowed value
THD AC voltage outside the
range
Check AC grid THD
173 STATUS 173
174 STATUS 174
175 ACout NOT
SYNC
The AC out is not
synchronized with grid
Check synchronization
between AC in and AC out
Check AC grid and
configuration
176 INV NOT SYNC The AC out is not
synchronized with grid
Check synchronization
between AC in and AC out
Check AC grid and
configuration
177 SYNC FAILURE Inverter not synchronized Check synchronization
between AC in and AC out
Check AC grid and
configuration
