LED indicators
Next to the display there are three LEDs: the first on the left (POWER) indicates that
the inverter works normally, the central one (FAULT) indicates a fault, while the one
on the right (GFI) indicates a failure to the ground.
1.
The green “Power” LED indicates that AURORA works correctly.
When the unit is started this LED flashes during grid check routine. If a valid grid
voltage is detected, the LED stays on permanent, as far as there is enough solar
radiation to activate the unit. If it is not so, the LED will go on flashing until solar
radiation is sufficient for unit activation. At this stage, the LCD shows the message
“Waiting sun….”
2.
The yellow “FAULT” LED indicates that AURORA has detected a fault. The
problem is displayed.
3.
The red “GFI” (ground fault) LED indicates that AURORA has detected a fault to
ground in photovoltaic field DC side. When this fault is detected, AURORA
immediately disconnects from grid and the LCD shows the relevant error warning.
AURORA stays in this state until the operator presses ESC to restart the grid
connection sequence. If AURORA can not reconnect to the grid it is necessary to
contact the authorised repair center to find and remove the cause of the fault.

The following chart shows all possible combination of LEDs activation according
to AURORA operating state.
