This information is made available through the Aurora Manager Lite
software.
• Date and time: setting necessary for the correct operation and storage
of statistical data of the inverter. It is set to UTC (daylight saving time is
NOT considered).
• RS485 address (1) and (2): settings required in the case of system
monitoring via the RS485 lines;
RS485 (1) default setting on AUTO
RS485 (2) default setting on AUTO
if multiple inverters are connected to the RS485 line, check that they
are assigned unique addresses. The addresses that can be assigned go
from 2 to 63.
• Vstart: Default 420 V
This section of the menu allows you to set the Vstart voltage (for the
two channels separately if they are congured independently) to suit the
system requirements.
We advise changing the activation voltage only if really necessary and to set it to the correct
value: the photovoltaic generator sizing tool available on the ABB website will indicate whether
Vstart needs changing and what value to set it at.
• Alarm
This section of the menu allows you to set the activation status of a relay
(available either as contact normally open – N.O. – or as contact normally
closed – N.C.) and to congure customised alarm conditions..
This contact can be used, for example, to: activate a siren or a visual alarm,
control the disconnect device of an external transformer, or control an
external device.
The relay can be set to switch in different modes:
• Production “PRODUCTION”
The production mode is the default mode.
The relay is activated (status: switched) whenever the inverter connects
to the grid; as soon as the inverter is disconnected from the network (for
whatever reason that caused disconnection), the relay is in its resting
position.
