ATTENTION – A
On each configuration the
maximum length of the cable must be 100m
between inverter – inverter and inverter –
switch.
ATTENTION – A
No initial setup is required
to start data transmission to Aurora Vision.
Internet connection is required to use all the
Aurora Vision remote functionalities.
NOTE – D
Please refer to Aurora Vision
documents available on ABB website for
further information how to get an Aurora
Vision account for remotely monitoring and
managing the installed solar assets.
11.4 Serial communication
connection (RS485)
ATTENTION – A
Please note that automatic
settings of network parameters at turning
on, embedded logging capability, automatic
logger-free transferring of data to Aurora
Vision Cloud and remote firmware update are
provided over TCP/IP (Ethernet and/or Wi-fi)
bus only.
NOTE – D
The use of the inverters over
the RS485 line is recommended in case of
monitoring and controlling by using third
party RS485 control systems.

The RS-485 serial communication line is available
on the communication and control board (26) with
two terminal blocks (43) for each serial line signal
(+T/R, -T/R and RTN) so as to be able to make a daisy-
chain connection (“in-out”) of multiple inverters.
Connection of the R485 communication line
conductors is made using the terminal block
connectors (43) (485+, 485-, RTN and SHIELD).
Slave mode
By default the RS485 port is set as Slave mode. In
case the port was set as “Master mode” it must
configured through the integrated Web User
Interface (refer to chapter “Web User Interface”) to
use the RS485 as a serial communication line.
The RS-485 port can be used to set up a line
of communication which, when connected to a
monitoring device, enables the operation of the
photovoltaic system to be kept under control.
Depending on the device used monitoring can be
local or remote.

RS485 line supports Modbus/RTU SUNSPEC
compliant Modbus protocol.
• When connecting a single inverter to the
monitoring system, activate the communication
line resistance terminal by setting the switch
(40) (to the ON position). In case of multiple
installation set the switch only on the last inverter
of the chain.
Master mode
The RS485 port can either be used for connecting
supported accessories (like weather station): in
this case data from accessories will be logged and
transferred to the cloud by inverter itself (master
mode).
This will allow the inverter to serve as a logger for
ABB accessories.
• When an accessory is connected set the switch of
the termination resistance (40) to“ON” position.
• When an accessory is connected it must be added
and configured into the “Monitored device” list
on the integrated Web User Interface.
NOTE – D
For more information on connecting
the accessories to the RS485 terminal block,
refer to the accessory product manual or
contact ABB customer support.
