- Error code
- Error message
- LED status
Name of Alarm and Cause Solution
- W025
- P-reduction
End
- No LED
Deactivation of reduction in power:
Indicates that the inverter has come out of one of
the power limitation states.
This type of warning does not need any check
- W026
- AFDD user
reset
- No LED
Reset of the Arc Fault error:
Manual reset of the Arc Fault error; this operation
can be made through the internal webserver.
• The reset of the Arc Fault error is done directly by
the customer/installer and is not an error. The
information is only saved on the historic record of
the events memorised by the inverter
- W046
- Grid conn.
fault
- Yellow LED
Connection to the grid unsuccessful
The alarm is logged when a Missing grid or Input UV
error occurs or due to the manual disconnection of
the inverter during the grid connection sequence.
• Once the error occurs, the inverter tries to return
to normal operation.
If the problem persists after a number of attempts
to connect the inverter, switch the inverter off and
then on again.
- If the problem persists (once the inverter has
been switched off and back on again), contact
customer assistance.
- W047
- Update
Incomplete
- Yellow LED
FW update method unsuccessful
The alarm occurs when a firmware update has not
been completed.
• Complete any pending firmware updates.
- If the problem persists once the firmware
updates have been completed, switch the inverter
off and on again.
- If the problem persists (once the inverter has
been switched off and back on again), contact
customer assistance.
- W048
- Periodic
GridOff
- Yellow LED
Automatic disconnection from the grid due to time
limit:
If the inverter exceeds the set grid connection time
limit set by the grid standard, it will automatically
have to carry out a disconnection and reconnection
to the grid to carry out the Riso test.
• The presence of this alarm is not an error as the
automatic disconnection is prescribed by safety
regulations.
- If the inverter disconnects in a shorter time than
expected, contact customer assistance.
- W049 *
- Global-
Settings Event
- No LED
Variation of the grid standard
Variation of the inverter's grid standard; this change
can be made through the Web User Interface.
• The variation in the inverter's grid standard is
done directly by the customer/installer and is not
an error. The information is only saved on the
historic record of the events memorised by the
inverter
- W058
- System Frozen
- Yellow LED
Converter in locked state:
The converter lock state is connected to an
installation phase in which the starts-up and grid
connection conditions are not yet present.
• Complete the commissioning phase of the
inverter.
- If the problem persists (once the commissioning
phase has been completed and the inverter has
been switched off and back on again), contact
customer assistance.
- E001
- Input OC
- Yellow LED
Input over-current (photovoltaic generator):
The alarm occurs when the inverter's input current
exceeds the inverter's threshold for maximum input
current.
• Check whether the composition of the PV
generator enables input current which exceeds the
maximum threshold allowed by the inverter and
that the configuration of the inputs (independent
or in parallel) is carried out correctly.
- If both checks are positive, contact customer
assistance.
- E002
- Input OV
- Yellow LED
Input overvoltage (photovoltaic generator):
The alarm is generated when the input voltage (from
the PV generator) exceeds the inverter's threshold of
maximum input voltage.
The alarm is triggered before reaching the absolute
threshold beyond which the inverter will be
damaged.
When the inverter's input voltage exceeds the Over
Voltage threshold, the inverter will not start up due
to the generation of the alarm.
• It is necessary to measure the input voltage
inside the inverter with a voltmeter.
- If it is higher than the maximum voltage of the
operating range, the alarm is genuine and it is
necessary to check the configuration of the PV
generator. 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
customer assistance.
- E003
- No pars (DSP)
- Yellow LED
DSP initialisation error:
The main microcontroller is unable to correctly
initialize the two DSPs (booster stage and inverter
stage). The error is caused by communication
problems on the inverter's internal bus.
• Error inside the inverter and cannot be checked
externally.
- If the problem persists (once the inverter has
been switched off and back on again), contact
customer assistance.
