Red LED
Ground fault of photovoltaic generator:
The alarm is generated when a leakage current to
ground is detected in the DC section of the system.
• Measure the insulation resistance using a megohmmeter posi-
tioned in the photovoltaic eld (positive terminal short-circuited
at the negative pole) compared to ground. The measurement is
strongly inuenced by the environmental conditions, so must be
taken under the same conditions in which the error occurred.
- If the value measured is lower than 1 megaohm, a check must
be carried out by a technician/installer on the photovoltaic gene-
rator to identify and eliminate the problem.
- If the value measured is higher than 1 megaohm and the error
signal persists, contact customer assistance.
- No code
- NEW COMPONENT
REFUSED!
-
Yellow LED lamp.
Lack of linkage of the new component:
The components inside the inverter (e.g. display, fuse
board, communication and control board, etc.) are not
inter-linked. This occurs following the replacement of one
of the components inside the inverter.
• Link the components inside the inverter by accessing the “Set-
tings > Service > Accept boards” (refer to the procedure given in
this manual).
- If the signal persists also following the linking of the compo-
nents, contact customer assistance.
- No code
- SET COUNTRY or NO
NATION
-
No LED
SET COUNTRY or NO NATION:
Indicates that in the installation phase the grid standard
was not set on the inverter.
• Set the grid standard of the country of installation following the
instructions given in this manual for the inverter.
- If the signal persists also following setting the grid standard,
contact customer assistance.
- No code
- Vac absent
-
Yellow LED
Vac absent:
The inverter displays the “Vac absent” message when it
does not record output voltage (AC side).
• Check the grid voltage on the inverter's AC terminal block.
- Should it be absent, check any protection work on the line and
the presence of grid voltage on the supply point.
- No code
- Mem. broken
-
Yellow LED
Memory broken:
The inverter displays the “Memory broken” message
when it records a communication problem with the me-
mory board on which the inverter saves the daily value
of energy produced.
• Remove the memory board and check the welding of all the
connector's terminals. Subsequently reinsert the memory board
and check that it is correctly inserted into the dedicated slot
- If the signal persists also following the above checks, contact
customer assistance.
- No code
- Awaiting sun
-
Green LED lamp.
Awaiting sun:
The inverter displays the “awaiting sun” message when,
following a W001 and/or W002 notice, the voltage from
the photovoltaic generator is less than the activation vol-
tage (Vstart).
• 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
- W001
- Sun Low
-
Yellow LED
Insufcient irradiation (Low input voltage on
switching on the inverter):
Incorrect conguration of the PV generator or an “on the
limit” conguration for the inverter's minimum input vol-
tage.
• 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
- W002
- Input UV
-
Yellow LED
Insufcient irradiation (Low input voltage on
switching off):
Incorrect conguration of the photovoltaic generator or
an “on the limit” conguration for the inverter's minimum
input voltage.
• 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
- W003
- Grid Fail
-
Yellow LED
Parameters of grid voltage outside range:
This error signal occurs when during the inverter's nor-
mal operation the grid parameters exceed the limits set
by the operator:
- Grid voltage absent (after the signal the inverter goes
to "Vac Absent")
- Unstable grid voltage (down or up) -
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 me-
asured 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
