- Error code
- Error message Name of Alarm and Cause
- LED status
Clock Fail:
- W013 The alarm occurs when there is a difference of
- Clock Fail more than 1 minute in the time shown on the Web
-
Flashing yellow User Interface compared to the internal time of the
LED microprocessors and indicates a malfunction of the
clock circuit.
- W015 Disconnection due to Anti-Islanding:
- Island Detect.
The inverter has been improperly connected to an
- Yellow LED island grid.

W021 Activation of reduction in power:
- P-reductionStart
Indicates that one of the power limitations has been
- No LED triggered.
Variation in means of managing reactive power:
- W022
Variation in the means of managing reactive power;
- Q-modeChange
this change can be made through the Web User
- No LED
Interface.
- W023 * Variation in the inverter's date and time:
- Date/time mod. Variation of the inverter's date and time; this change
- No LED can be made through the Web User Interface.
Zeroing of the statistical energy data memorised
- W024 in the EEPROM:
- Energy data rst Reset of the energy data saved in the inverter; this
- No LED operation can be handled through the Web User
Interface.
W025 Deactivation of reduction in power:
- P-reductionEnd
Indicates that the inverter has come out of one of the
- No LED power limitation states.
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.
Solution
• Error inside the inverter and cannot be checked externally.
- If the alarm repeats persistently, contact customer
assistance.
• Check that the grid to which the inverter is connected is not
an island grid.
- If the grid to which the inverter is connected is an island
grid, switch the inverter off and then on again: if the problem
persists, contact customer assistance.
• 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.
• 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.
• 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
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.
• 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.
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
This type of warning does not need any check
• 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.
