- LED status
Name of Alarm and Cause Solution
- W012
- Batt. Low
- Flashing
yellow LED
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.
- W013
- Clock Fail
- Flashing
yellow LED
Clock Fail:
The alarm occurs when there is a difference of more
than 1 minute in the time shown on the Web User
Interface 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 assistance.
- 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.
- 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
