Name of Alarm and Cause
- Warning
Deactivation of reduction in power:
W025
Indicates that the inverter has come out of one of the
- P-reductionEnd
power limitation states described in the paragraph
-
No LED
"Power limitation messages".
- W026
Reset of the Arc Fault error:
- AFDD user reset
Manual reset of the Arc Fault error; this operation can
-

be made through the internal webserver.
- W027
Resetting of the Latch alarm conditions:
- Latch-Manual reset
Manual reset of the Latch alarm conditions; this
-
No LED
operation can be made through the internal
webserver.
- W030
METER device communication problem:
- Energy Meter
Error detected on the RS485 serial communication
ERROR *
line between the inverter and the energy meter
-
No LED
(METER).
Disconnection of system from grid:
- W045
Warning of disconnection of system from electrical
- Sys disconnected
grid (no DC input voltage) because of dead battery
-
Yellow LED
pack or no demand from domestic loads
Connection to the grid unsuccessful
- W046
The alarm is logged when a Missing grid or Input UV
- Grid conn. fault
error occurs or due to the manual disconnection of the
-
Yellow LED
inverter during the grid connection sequence.
- W047
FW update method unsuccessful
- Update Incomplete
The alarm occurs when a firmware update has not
-
Yellow LED
been completed.
Automatic disconnection from the grid due to time
limit:
- W048
If the inverter exceeds the set grid connection time
- Periodic GridOff
limit set by the grid standard, it will automatically have
-
Yellow LED
to carry out a disconnection and reconnection to the
grid to carry out the Riso test.
- W049
Variation of the grid standard
- Global-Settings
Variation of the inverter's grid standard; this change
Event
can be made through the internal webserver.
-
No LED
Converter in locked state:
- W058
The converter lock state is connected to an installation
- System Frozen
phase in which the starts-up and grid connection
-
Yellow LED
conditions are not yet present.
Input over-current (photovoltaic generator):
- E001
The alarm occurs when the inverter's input current
- Input OC
exceeds the inverter's threshold for maximum input
-
Yellow LED
current.
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.
- E002
The alarm is triggered before reaching the absolute
- Input OV
threshold beyond which the inverter will be damaged.
-
Yellow LED
When the inverter's input voltage exceeds the Over
Voltage threshold, the inverter will not start up due to
the generation of the alarm.
Solution
This type of warning does not need any check
• 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
• The reset of the Latch alarm conditions 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
• Check the serial communication line connections between
the inverter and the METER. Particularly check the signal
correspondence, the correct installation of the conductors and
that there are no breaks in the cables.
• Faulty communication card (Comm. card)
• 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.
• Check that, when the warning occurs, the battery pack
is dead and/or there have been no energy demands from
domestic loads for more than 10 minutes.
• 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.
• 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.
• 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.
• 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
• 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.
• 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.
• 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.
