Battery Low:
The inverter has detected a backup battery voltage
that is too low.
• Check that the date/time are set correctly and, if they are not,
set them.
Subsequently arrange to completely switch off the inverter (on
both AC and DC) and wait a few minutes.
Finally, restart the inverter and check whether the date/
time are now correctly set or whether they have reset to
01/01/2000. In this case replace the battery with the inverter
completely switched off (isolate AC and DC side) being careful
to maintain the polarity

- Clock Fail
- Flashing yellow
LED
*not visualised on
display
Clock Fail:
The alarm occurs when there is a difference of more
than 1 minute in the time shown on the display or via
the advanced configuration software compared to the
internal time of the microprocessors and indicates a
malfunction of the clock circuit.
• Error inside the inverter and cannot be checked externally.
- If the alarm repeats persistently, contact customer assistan-
ce.
- W015
- Island Detect.
- Yellow LED
Disconnection due to Anti-Islanding:
The inverter has been improperly connected to an
island grid.
• 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.
- W017*
- String Err.
-
Flashing yellow
LED
* (only for models with
monitored string fuses)
Error recorded in measuring string currents:
Damaged string protection fuse(s)
• Check with a multimeter the state of the fuses (positioned on
the fuse boards).
- If one or more fuses is open, arrange to replace them and
check that the input current on the string(s) does not exceed
the rating of the fuses (should parallel strings have been made
outside the inverter).
- If there are no damaged string fuses and the inverter conti-
nues to show the alarm message check whether the settings
to be made via the Aurora Manager software are correct
(presence or absence of one or more input strings).
- W018 *
- SPD DC Err
- 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 cartrid-
ge must be replaced.
- If the alarm status persists, even if all the surge arresters
have a green inspection window, contact customer assistance.
- W019 *
- SPD AC Err
-
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 cartrid-
ge must be replaced.
- If the alarm status persists, even if all the surge arresters
have a green inspection window, contact customer assistance.

Activation of reduction in power:
Indicates that one of the power limitations described in
the paragraph "Power limitation messages" 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

- Reactive power
mode changed
- No LED
*not visualised on
display
Variation in means of managing reactive power:
Variation in the means of managing reactive power;
this change can be made through the display or
advanced configuration software.
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 changed
- No LED
*not visualised on
display
Variation in the inverter's date and time:
Variation of the inverter's date and time; this change
can be made through the display or advanced confi -
guration software.
• 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
