- Error code
- Error message Name of Alarm and Cause
- Warning
Grid overvoltage:
- W004
This error signal occurs when during the inverter's
- Grid OV
normal operation the grid voltage exceeds the
- Yellow LED
maximum limit set by the operator.
Grid undervoltage:
- W005
This error signal occurs when during the inverter's
- Grid UV
normal operation the grid voltage exceeds the
- Yellow LED
minimum limit set by the operator.
Grid over-frequency:
- W006
This error signal occurs when during the inverter's
- Grid OF
normal operation the grid frequency exceeds the
- Yellow LED
maximum limit set by the operator.
Grid under-frequency:
- W007
This error signal occurs when during the inverter's
- Grid UF
normal operation the grid frequency exceeds the
- Yellow LED
minimum limit set by the operator.
- W009
Characterisation board for the wind generator not
- Empty Table
compiled (only WIND models)
- Yellow LED
- W010 *
- Fan Fail
Fan Fail:
- Flashing yellow
This error occurs when there is a malfunction in the
LED
fan/fans inside the inverter.
*not visualised on
display
Low "Bulk" voltage (DC-DC circuit):
The alarm (which is a warning and not an error)
- W011
is generated when the voltage at the heads of the
- Bulk UV
bulk capacitors does not reach the threshold for
- Yellow LED
the operation of the inverter (internal unchangeable
threshold).
- W012 *
- Batt. Low
Battery Low:
- Flashing yellow
The inverter has detected a backup battery voltage
LED
that is too low.
*not visualised on
display
Clock Fail:
- W013 *
- Clock Fail The alarm occurs when there is a difference of more
- Flashing yellow than 1 minute in the time shown on the display or via
the advanced configuration software compared to the
LED
*not visualised on internal time of the microprocessors and indicates a
display malfunction of the clock circuit.

Solution
• Check the grid voltage on the inverter.
If the voltage tends to rise (when the inverter is connected),
there is a problem of high line or grid impedance.
• Check the grid voltage also on the supply.
- If it is high, it means that there is high grid impedance. In
this case, ask the operator to adjust the grid voltage. If the
operator authorises a change to the inverter's parameters,
agree the new limits with customer assistance
- If the voltage at the point of supply is much lower than that
measured on the inverter, it is necessary to adjust the line
(inverter-contactor).
- If the voltage and the grid frequency come back within the
limits (also when the inverter is connected to the grid), contact
customer assistance
• Check the grid voltage on the inverter.
• Check the grid voltage also on the supply.

customer assistance
• Check the grid frequency in the inverter.
• Check the grid frequency also on the supply:
- If the voltage and the grid frequency come back within the
limits (also when the inverter is connected to the grid), contact
customer assistance
• Check the grid frequency in the inverter.
• Check the grid frequency also on the supply:
- If the voltage and the grid frequency come back within the
limits (also when the inverter is connected to the grid), contact
customer assistance
(only WIND models)
• Error inside the inverter and cannot be checked externally.
- If the alarm repeats persistently, contact customer
assistance.
• Raise the value of the activation voltage (Vstart) so as to
have sufficient power from the PV generator at the time of the
inverter's grid connection.
• Check the input voltage on the inverter.
- If it does not exceed Vstart, check for the presence of
sufficient irradiation and the correct composition of the system.
- If it exceeds Vstart, contact customer assistance.
• 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
• Error inside the inverter and cannot be checked externally.
- If the alarm repeats persistently, contact customer
assistance.
