• Select the country standard and the configuration of the input
channels (INDIPENDENT OR PARALLEL mode - parallel mode
is only available on standard and S2 models) and confirm the
setting by clicking “DONE”.
The image shows the successful commissioning.
In the SETTINGS section it’s possible to access the following sub-
menus:
RS485 (allows to set address, baud rate, parity mode and
communication protocol.
LAN (it’s possible to view the status and change the daisy chain
configuration of the two ethernet ports of the inverter).
WLAN (it’s possible to view the status of the two wireless channels
of the inverter, and to disconnect the channel 2).
Monitored Devices (it’s possible to add and config the connected
supported accessories to the RS485. In this case, modify the data
on the rs485 tab according to the characteristics of the inserted
device).
NOTE – D For any other specific settings of parameters of
single inverters please refer to “Web User Interface menu
structure” paragraph.
• After the commissioning via the Fimer Installer for Solar Inverters
APP is completed, the inverter changes the behaviour of the
“Power” and “Alarm” LEDs (08) , in relation of the input voltage
value:
Input

Status
Description
Vin < Vstart
Power = Flashing
Alarm = OFF
The input voltage is
not sufficient to enable
connection to the grid.
Vin > Vstart
Power = Flashing
Alarm = ON
The input voltage is sufficient
to enable connection to the
grid: the inverter waits for the
grid voltage to be present
to make the connection to
the grid.
• Depending of the supply source used to complete the installation
wizard steps, close the disconnect switch of missing voltage
sources: In case of missing AC source close the AC switch
downstream of the inverter (and AC disconnect switch (09) for
the -S2, -SX2, SY2 wiring box versions); In case of missing DC
source close the DC disconnect switches (15).
• When the input voltage is sufficient to allow the connection to the
grid, the inverter will check the grid voltage, measure the isolation
resistance of the photovoltaic field with respect to ground and
performs other auto-diagnostic checks. During the preliminary
checks on the parallel connection with the grid, the “Power”
LED keeps flashing, the “Alarm” and “GFI” LEDs are OFF. The
inverter will ONLY connect to the grid if all parameters fall within
the ranges foreseen by current regulations.
• If the outcome of the preliminary checks to grid synchronization
are positive, the inverter connects and starts to export power to
the grid. The “Power” LED remains fixed on while the “Alarm” and
“GFI” LEDs are OFF.
NOTE – D To address any problems that may occur during
the initial stages of operation of the system and to ensure
the inverter remains fully functional, you are advised to check
for any firmware updates in the dedicated section of web
user interface (“SERVICE TOOLS menu”), via Installer for
Solar Inverters APP or in the download area of the website
www.fimer.com or at https://registration.solar.fimer.com
(refer to ““Registration website” and “Admin Plus
token”” paragraph).
