7.3 LEDs behaviour
03
POWER
Indicates that the inverter is functioning correctly.
ALARM
Indicates that the inverter has detected an anomaly.
The type of problem could be checked in the Web UI and FIMER Installer for Solar Inverters APP.
GFI
The “GFI” (ground fault) indicates that the inverter has detected a ground fault in the DC side photovoltaic generator.
WLAN/LAN
Indicates the status of the Wi-Fi or Ethernet communication lines.
The following table shows the possible activation combinations of “Power” “Alarm” and “GFI” LED icons on the Sinoptic
(03)
according to
the operating status of the inverter.
Each LED icon could behave in one of the following ways:
= ON
= Flashing slow (2 seconds on / 2 seconds off)
= Flashing fast (0.2 seconds on / 0.2 seconds off)
= OFF
= Any one of the conditions described above

POWER:
ALARM:
GFI:
Firmware programming
The inverter firmware is being programmed (never turn off the inverter during this phase).
POWER:
ALARM:
GFI:
Night time
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)
POWER:
ALARM:
GFI:
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.
POWER:
ALARM:
GFI:
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).
POWER:
ALARM:
GFI:
Missing grid
Indicates lack of grid voltage. This condition does not allow the inverter to connect to the grid.
