Operating state
green:
Firmware programming
yellow:
The inverter firmware is being programmed.
red:
green:
Night mode (inverter automatically switches off)
yellow:
The inverter is in night time switch-off mode (input voltage less than 70% of the set start-up
red:
voltage and AC grid is missing).
green:
Inverter initialization / Waiting Sun
yellow:
This is a transitional state due to verification of the operating conditions. During this stage the
red:
inverter checks that the conditions for connecting to the grid are met.
green:
The inverter is connected and is feeding power into the grid
yellow:
Normal operation. During this stage, the inverter automatically tracks and analyses the pho-
red:
tovoltaic generator's maximum power point (MPP).
green:
Missing grid
yellow:
Indicates lack of grid voltage. This condition does not allow the inverter to connect to the grid.
red:
Warning indication: (W message codes) or Error: (E message codes)
green:
- Indicates that the inverter control system has detected a warning (W) or error (E). It is possible to
yellow:
identify the type of problem generated in the dedicated section of integrated Web User Interface
red:
("Inverter Log" section).
green:
Temperature protection trip
yellow:
Indicates that the trip relating to internal temperatures (insufficient or excessive temperature)
red:
may have been activated.
green:
Anomaly in the insulation system of the photovoltaic generator
yellow:
Indicates that a leakage to earth from the PV generator has been detected, causing the in-
red:
verter to disconnect from the grid.
The following table shows all the possible activation combinations of
"Power" "Alarm" and "GFI" LEDs on the LED panel
operating status of the inverter.
All possible LED activation combinations are shown in the following ta-
ble. 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
- 110 -
7 - Operation
