CONNECTION DIAGRAM
Figure A1 –ABB Inverter Communication Card
Connection Steps:
1. Open the bottom of the Inverter as shown in Figure A1 using Star Key.
2. Locate the Communication Board inside the DC Wiring Box as shown in Figure A2.
3. Please ensure you have female 12 pin connector to connect wires & plug in to the board.
4. Connect the TrackSo IoT gateway to any one of the RS-485 ports as shown in Table AT1.

CONFIGURATION AT THE INVERTER END
SETTING THE BAUD RATE
If you connect multiple inverters via RS485, set the same baud rate on each inverter.
SETTING THE INVERTER ID
The inverter ID is used to identify the inverter in a RS485 connection
•Set a different inverter ID for each inverter in the PV plant. Otherwise, the inverters cannot be correctly identified.
•No inverter should have “Auto” as its address. An address can be chosen freely from out of 2 to 63.
•On the last inverter in the RS485 connection, switch on the RS485 termination resistor.
Set the Inverter baud rate to 9600
Set correct Inverter Ids

SET DATE & TIME OF INVERTER
For a precise calculation of the statistics in the inverter itself and in a monitoring system, date and time have to be correct.
SET COMMUNICATION PROTOCOL
Communication Card Settings
Set the RS-485 termination resistance based on where the inverter is located in a daisy chain
Single Inverters
If a single inverter is connected to the monitoring system, activate the termination resistance of the communication line by
switching switch a12 or a13 (to ON position).
Set the Correct Date & Time
Select Modbus RTU
Communication Protocol

Multiple Inverters
Connect all the units of the RS485 chain in accordance with the “daisy chain” arrangement (“in-out”) observing the correspondence
between signals, and activate the termination resistance of the communication line in the last element of the chain by switching
switch a12 or a13 (to ON position) being careful to switch the switch of the serial line used (PC or PMU).
The above details are also mentioned in the Installation & Operation Manual for ABB Inverters

TRACKSO WORKING
1. Insure correct connections as detailed in the installation guide.
2. Insert the SIM card.
3. Switch on the power to the TrackSo device. (Minimum 12V/1A input is required)
4. Power LED (Red) of TrackSo IoT gateway glows and stays ON.
NOTE: TrackSo IoT Gateway will only be able to send data if the GPRS network is available at the
installed location.
