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 wiring box version); In case of
missing DC source close the DC disconnect switches (19).
• 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).
LEDs behaviour
All possible LED (08) activation combinations are shown in the following table. In particular, each LED
could behave in one of the following ways:
= LED on
= LED flashing slow (2 seconds on / 2 seconds off)
= LED flashing fast (0.2 seconds on / 0.2 seconds off)
= LED off
= Any one of the conditions described above
The following table shows all the possible activation combinations of “Power” “Alarm” and “GFI” LEDs
on the LED panel (08) according to the operating status of the inverter.

Night mode (inverter automatically switches off)
The inverter is in night time switch-off mode (input voltage less than 70% of
the set start-up voltage and AC grid is missing).

Inverter initialization / Waiting Sun
This is a transitional state due to verification of the operating conditions.
During this stage the inverter checks that the conditions for connecting to the
grid are met.

The inverter is connected and is feeding power into the grid
Normal operation. During this stage, the inverter automatically tracks and
analyses the photovoltaic generator’s maximum power point (MPP).
