1 Introduction
This quick guide demonstrates how to commission the SG30/50/110CX inverters and should be read in conjunction with the Sungrow User Manuals. For installations with multiple inverters or an energy meter, commissioning and iSolarCloud connection are managed via a Logger1000 (supporting up to 30 devices) or EyeM4 (supporting up to 10 devices).
An energy meter, such as the DTSD1352-C/1(6)A with an external CT, is required for export control and load consumption monitoring. All components are connected using a daisy-chain configuration following standard RS485 topology.

2 RS485 Connections
2.1 Inverter Connection (Daisy Chain)
It is recommended that RS485 connections are made using terminal blocks. Note that SG15/20KTL-MT inverters have a different connection method compared to SG30/50/110CX inverters.
Diagram: Shows the terminal block connections for RS485 communication (A1, B1, PE) on inverters. It also illustrates the daisy-chain connection where the output of one inverter connects to the input of the next. An optional note indicates that termination resistors (120 Ohm) should be enabled ON (SW1) at each end of the RS485 line (first and last inverter) if more than 15 inverters are connected.
2.2 Energy Meter Connection
The site electrician must calculate the required CT ratio based on the installation. The default Modbus address is 1, and the secondary current of the CT should be 5A. Refer to the Meter Selection Guide for detailed information.
For RJ45 connections, Pin 3 (White-green) corresponds to RS485- B, and Pin 6 (Green) corresponds to RS485+ A. The communication cable uses specific color codings: White-orange (Pin 1), Orange (Pin 2), White-green (Pin 3) for RS485- B, Blue (Pin 4), White-blue (Pin 5), Green (Pin 6) for RS485+ A, White-brown (Pin 7), Brown (Pin 8).
