CONNECTION DIAGRAM
Locate communication terminals (RS485) as shown in the picture below. There are two connection terminals on the
configuration circuit board: RS485IN and RS485OUT (used for Daisy Chain connections)
Figure S1: SOFAR String Inverter communicatio port & Connections
Connection steps
•Please unscrew the RS485 terminal as shown in A part of Figure
S1.
•Please make the connections from the Terminal Block to
TrackSo IoT Gateway as mentioned in Table –ST1.
•Provide 12V external supply to TrackSo IoT Gateway via 12V, 2A
DC adaptor provided in the package

In case you are using the RJ45 connector to connect with the datalogger below is the wire config
Join the following wires from CAT6 cable to get RS485
connections
Data + (RS485 +) = 2nd + 3rd + 4th
Data –(RS485 -) = 1st + 5th + 6th
DEFAULT CONFIGURATION IN TRACKSO IOT GATEWAY
Inverter ID: 1, 2, 3, 4 …. Continuous numbering starting with 1, (Range: 1 to 247)
Baud Rate: 9600 (Default) (Values: 9600, 19200, 38400)
Data Bits: 8 ,Stop Bit: 1 ,Parity: None
CONFIGURATION AT THE INVERTER END
Inverter Screen has 4 buttons Back, Up, Down, Ok

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.
•On the last inverter in the RS485 connection, switch on the RS485 termination resistor.
•Users press “Back” button to enter “1.Enter setting” interface, Press ”OK“ button to enter main setting interface.
•Enter “9. Set Address” by pressing “Up” button or ”Down“ button.
•Press “OK” button and enter setting interface “Success” or “fail” is displayed after setting.
SET D ATE & T IME O F INVE RTER
For a precise calculation of the statistics in the inverter itself and in a monitoring system, date and time have to be correct.
•Users press “Back” button to enter “1.Enter Setting” interface, Press “OK button to enter main setting interface.
•Enter “1. Set Time” by pressing“Up” button or “Down” button, then press”OK“button and start to set up time.
•Time set from year, month, day, minutes, & seconds in turns, “Up or “Down”button to choose different value to set date.
•Set each value is need to press “OK” button to confirm setting. “success” is displayed if the setting time is correct, “fail”
means failure settings
Communication Card Settings
Set the Correct Date & Time
Set correct Inverter Ids

Single Inverter Terminal Resistor-off
Multiple Inverters
If multiple SOFAR Inv are used, connect all SOFAR Inv in daisy chain mode over theRS485 communication cable. Set different
Modbus address(1~31) for each inverter in LCD display and set SWT2 (match resistance) at the first and last inverter
NOTE: The above details are mentioned in the Installation & Operation Manual of SOFAR Inverters
