Connection and Commissioning Quick Guide for
SG30/50/110CX Inverters
Disclaimer
The material in this document has been prepared by Sungrow Australia Group Pty. Ltd. ABN 76
168 258 679 and is intended as a guideline to assist solar installers for troubleshooting. It is not a
statement or advice on any of the Electrical or Solar Industry standards or guidelines. Please
observe all OH&S regulations when working on Sungrow equipment.
Applicability: SG30CX, SG50CX and SG110CX; DTSD1352.
Notes:
This quick guide is to be read in conjunction with the Sungrow’s User Manuals and
SG30/50/110CX inverters as example for demonstration.
When more than one inverter is installed, all the commissioning is done via the
Logger1000.
All of the components are connected via daisy-chain RS485 as per standard RS485
topology.
For export control and load consumption, an energy meter needed to be connected.
Default baud rate is 9600 of the energy meter and this can be changed if necessary,
by entering “System/Interface/RS485” in the Logger1000.
Shielded twisted pair with a minimum CSA of 0.75mm should be used, and the
maximum total length of the cable is 1,200m (120 Ohm resistor should be
terminated).

Overview
Schematic layout of equipment to the logger1000.
Note: 120 Ohm termination resistors are integral to the Sungrow range of inverters and the
last item in the chain should be terminated with a 120 Ohm resistor (6 supplied).

RS485 Topology
The RS485 can be connected either by direct cable connection or RJ45 plugs.
Please note SG15/20KTL-MT inverters connection is different as SG30/50/110CX inverters.
Ensure the termination resistors are enabled at each end of the RS485 in the inverter
line.

Energy Meter Connection
The site electrician will need to calculate the CT ratio required as per the installation.
The CT ratios can be set by accessing the DTSD1352 energy meter menu. Please
refer Meter Selection Guide for reference.
Default Modbus address is 1 and the secondary current of CT should be 5A.
The corresponding pinouts to RJ45 are Pin 3 (White-green) to RS485- B and Pin 6
(Green) to RS485+ A:
Terminal 21 to Green cable (RS485+ A) and terminal 22 to White-green cable
(RS485- B) on the DTSD1352 energy meter side. The following figures shows the
meter cable connection on the eneryg meter side.
Connect to Logger1000 via the RS485 cable from the energy meter on RS485 port
A2 and B2.

Inverter connection to Logger1000
Connect the RS485 comms from the inverter(s) via A1/B1 and the energy meter via
A2/B2 to the Logger1000.
On the logger1000 side, A1 and B1 are terminals to connect with the inverter which
display as com1 on the Logger1000 web portal; A2 and B2 are the terminals to
connect with the energy meter, they are shown as com2 on the portal.
On the inverter SG30/50/110CX side, the RS485 cable should be plugged into the
terminal shown in the following figure which highlighted in red circle.

Set date and time
Select Clock Source to ‘NTP’ and Time Zone to ‘UTC+10:00’and make sure to Save
Device list
Navigate to ‘Device’ section and click ‘Auto search’; the connecting devices will be
display under ‘Device List’ section if connection is correct. Sungrow’s inverters will be
automatically detected as long as they are correctly connected and energised.
Meanwhile, you can confirm the communication status for each device under
Communication status section. Green icon indicates the connection works and red
icon means no connection between Logger1000 and other device.
