The input voltage is not suffi cient to permit con-

Vin>Vstart No Vac
Green=FLASHING
Yellow=ON
Red=OFF There is suffi cient input voltage to permit connec-
tion to the grid: the inverter waits until there is grid
voltage to carry out the parallel.
9. start up and connection to the grid
Once the pre-commissioning checks have been performed, it is possible to proceed to starting up the inverter
and connecting it to the grid, following the procedure shown below.
note: the inverter is powered ONLY by the voltage coming from the photovoltaic generator: presence of grid voltage
alone IS NOT SUFFICIENT to permit the inverter to start up.
note: the inverter start-up voltage (Vstart) is the input voltage value though which the inverter connects to the grid.
This value avoids repeated connection and disconnection in periods of reduced radiation (typically in the morning).
It is possible to modify the start-up voltage within a set range via the display and the four keys (Ref. Par. 10 and the
technical data table in Appendix C).
You are recommended to reduce the start-up voltage only when absolutely necessary, i.e. when the Confi gurator
software indicates that the parameter needs to be changed to avoid repeated connection and disconnection to the AC
Grid which could impact the reliability of the AC grid relays.
note: the start-up voltage also sets the minimum voltage for the inverter to operate in MPPT. The inverter turns itself
off because of input undervoltage when the input voltage (for each channel) drops below 70% of the start-up voltage
(for the channel).
note: during the grid voltage check and measurement of the insulation resistance, the values for the grid voltage and
frequency and the insulation resistance measured by the inverter are shown on the display. The inverter completes
parallel with the grid SOLELY if the grid parameters meet the ranges provided for by the regulations in force and if the
insulation resistance is greater than 1Mohm.
With the inverter in “No Vac” status, close the AC switch downstream the inverter so as to apply the grid
voltage to the inverter: the inverter performs the grid voltage check, measures the photovoltaic fi eld’s
insulation resistance against earth and carries out other self-diagnosis checks. During the checks before the
parallel with the grid, the green LED keeps fl ashing, the others are off.
Switch the integrated switch (versions –S and –FS) to the ON position or close the external switches: If the input voltage
applied to one of the two input channels is greater than the minimum starting voltage, the inverter will start up.
When the inverter starts up for the fi rst time it asks you to select the “Nation” of the country where it has been installed. See
section 10.1 for more details about selecting the “Nation”. After you have set the Nation value, the message "Inizializing...
Please Wait" is displayed.
Depending on the input voltage value, the inverter will show various messages on the display and change
the behaviour of the three LED:
