1) Night-time Mode
AURORA is in the nighttime disconnection phase; this happens
whenever the input power is too low to export power to the grid
and power the inverter control system as well.

2) AURORA Initialization and Grid Check
The unit is in the initialization phase: energy supply for the
inverter control system is high enough. AURORA is also
checking that starting conditions – such as input voltage, starting
time, etc. - necessary for the initialization process, are satisfied.
Grid check is then started.

3) AURORA Under Production
Once all electronic and safety self-tests are successfully
completed, the unit starts the exporting process.
As stated above, during this phase AURORA carries out an
automatic search and analysis of the photovoltaic field max power
point tracking (MPPT).

4) Ground Insulation
The inverter signals a ground fault.
This can be due to an insulation defect on the photovoltaic field
connection (ex. Insulation resistance too low)
¾ Insulation Defect
An insulation fault condition has been detected in the
photovoltaic field or in the corresponding connection: a
connection is conductive with the grounded potential.
WARNING: trying to remove the fault by yourself is
extremely dangerous. The instructions below have to be
followed very carefully. In case you are not experienced or
skilled enough to work safely on the unit, contact a specialized
technician.
What to do after an insulation defect has been found
Whenever the red LED comes on, press the special multifunction
push-button next to the LCD side to reset it. If this fault can be
reset, the AURORA will continue working because the fault was
