- Error message
- LED status
Name of Alarm and Cause Solution
- W018 *
- DC SPD tripped
-
Flashing yellow LED
* (only for models with
monitored SPD)
Intervention of overvoltage surge arresters
on DC side:
Overvoltage surge arresters situated on
the DC side are damaged.
• Observe the inspection window on each surge arrester
(DC side). If it is red, the surge arrester is damaged and the
cartridge must be replaced.
- If the alarm status persists, even if all the surge arresters have
a green inspection window, contact customer assistance.
- W019 *
- AC SPD tripped
-
Flashing yellow LED
* (only for models with
monitored SPD)
Intervention of overvoltage surge arresters
on AC side:
Overvoltage surge arresters situated on
the AC side are damaged.
• Observe the inspection window on each surge arrester
(AC side). If it is red, the surge arrester is damaged and the
cartridge must be replaced.
- If the alarm status persists, even if all the surge arresters have
a green inspection window, contact customer assistance.
- W021
- P-reduction Start
-
No LED
Activation of reduction in power:
Indicates that one of the power limitations
has been triggered.
• Check which power limitation code is active and, on the basis
of that, carry out the necessary checks that might relate to
various factors including:
- settings by the user
- high grid frequency
- high grid voltage
- anti-islanding
- low grid voltage
- high internal temperature
- high input voltage
- W022
- Q-mode Change
-
No LED
Variation in means of managing reactive
power:
Variation in the means of managing
reactive power; this change can be made
through the Web User Interface.
The variation in the means of managing reactive power 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.
- W023 *
- Date/time mod.
-
No LED
Variation in the inverter's date and time:
Variation of the inverter's date and time;
this change can be made through the Web
User Interface.
• The variation in the inverter's date and time 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.
- W024
- Energy data rst
-
No LED
Zeroing of the statistical energy data
memorised in the EEPROM:
Reset of the energy data saved in the
inverter; this operation can be handled
through the Web User Interface.
The zeroing of the partial energy values memorised by the
inverter 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 warning may also occur when the Memory Card on which
the production statistics are saved is replaced
- 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.
