Name of Alarm and Cause Solution
- W003
- Grid Fail
- Yellow LED
Parameters of grid voltage outside range:
This error signal occurs when during the inverter's
normal operation the grid parameters exceed the
limits set by the operator:
- Grid voltage absent (after the signal the inverter
goes to "Missing Grid")
- Unstable grid voltage (values too low or too high)
- Unstable grid frequency
• Check the grid voltage on the inverter.
- Should it be absent, check for absence of grid voltage on the
supply point.
- If, on the other hand, the voltage tends to rise (when the
inverter is connected) there is 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
- W004
- Grid OV
- Yellow LED
Grid overvoltage:
This error signal occurs when during the inverter's
normal operation the grid voltage exceeds the
maximum limit set by the operator.
• 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
- W005
- Grid UV
- Yellow LED
Grid undervoltage:
This error signal occurs when during the inverter's
normal operation the grid voltage exceeds the
minimum limit set by the operator.
• Check the grid voltage on the inverter.
• 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
- W006
- Grid OF
- Yellow LED
Grid over-frequency:
This error signal occurs when during the inverter's
normal operation the grid frequency exceeds the
maximum limit set by the operator.
• 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
- W007
- Grid UF
- Yellow LED
Grid under-frequency:
This error signal occurs when during the inverter's
normal operation the grid frequency exceeds the
minimum limit set by the operator.
• 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
- W010 *
- Fan Fail
- Flashing yellow
LED

display
Fan Fail:
This error occurs when there is a malfunction in the
fan/fans inside the inverter.
• Error inside the inverter and cannot be checked externally.
- If the alarm repeats persistently, contact customer
assistance.
- W011
- Bulk UV
- Yellow LED
Low “Bulk” voltage (DC-DC circuit):
The alarm (which is a warning and not an error)
is generated when the voltage at the heads of the
bulk capacitors does not reach the threshold for
the operation of the inverter (internal unchangeable
threshold).
• Raise the value of the activation voltage (Vstart) so as to
have sufcient 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
sufcient irradiation and the correct composition of the system.
- If it exceeds Vstart, contact customer assistance.
