missing
NOTE: In correspondence with each of the inverter states, signaled via
the constant or intermittent lighting up of the relevant LED, a message
identifying the operation which is being performed or the fault/defect
detected will also be displayed on AURORA LCD display (see the
following paragraphs).
G

R 1) Night-time mode
AURORA is in its night-time shut-down phase; this happens
when the input power is too low to feed the inverter.

2) AURORA initialization and grid check
The machine is in its initialization phase. Input power is
sufficient to feed the inverter. AURORA is checking that the
conditions necessary for start-up have been satisfied (for
example, input voltage value, isolation resistance value, etc.), and
starts the grid check.

3) AURORA is feeding the grid
After having completed the series of autotests on electronic and
safety aspects, the machine starts the grid connection process.
As previously mentioned, AURORA will automatically perform
a search and analysis of the maximum power point (MPPT) of
the photovoltaic field.

4) Ground isolation fault
AURORA indicates that the isolation resistance value is too low.
The problem may be linked to an isolation fault in the connection
between the photovoltaic field inputs and the ground.
WARNING: it is extremely dangerous to attempt to correct
the fault yourself. The instructions below must be followed
very carefully. Please contact a specialist if you do not possess
