Solution
• Check that the grid to which the inverter is connected is not
an island grid.
- If the grid to which the inverter is connected is an island
grid, switch the inverter off and then on again: if the problem
persists, contact customer assistance.
• Check with a multimeter the state of the fuses (positioned on
the fuse boards).
- If one or more fuses is open, arrange to replace them and
check that the input current on the string(s) does not exceed
the rating of the fuses (should parallel strings have been made
outside the inverter).
- If there are no damaged string fuses and the inverter
continues to show the alarm message check whether the
settings to be made via the Aurora Manager software are
correct (presence or absence of one or more input strings).
• Observe the inspection window on each surge arrester
(DC side). If it is red, the surge arrester is damaged and the
cartridge must be replaced.
- If the alarm status persists, even if all the surge arresters
have a green inspection window, contact customer assistance.
• Observe the inspection window on each surge arrester
(AC side). If it is red, the surge arrester is damaged and the
cartridge must be replaced.
- If the alarm status persists, even if all the surge arresters
have a green inspection window, contact customer assistance.
• Check which power limitation code is active and, on the
basis of that, carry out the necessary checks that might relate
to various factors including:
- settings by the user
- high grid frequency
- high grid voltage
- anti-islanding
- low grid voltage
- high internal temperature
- high input voltage
The variation in the means of managing reactive power is
done directly by the customer/installer and is not an error. The
information is only saved on the historic record of the events
memorised by the inverter
• The variation in the inverter's date and time is done directly
by the customer/installer and is not an error. The information is
only saved on the historic record of the events memorised by
the inverter
The zeroing of the partial energy values memorised by the
inverter is done directly by the customer/installer and is not an
error. The information is only saved on the historic record of
the events memorised by the inverter
• The warning may also occur when the Memory Card on
which the production statistics are saved is replaced
This type of warning does not need any check
• The reset of the Arc Fault error is done directly by the
customer/installer and is not an error. The information is only
saved on the historic record of the events memorised by the
inverter
