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.

Introduction

This quick guide is to be read in conjunction with the Sungrow's User Manuals and SG30/50/110CX inverters as example for demonstration. For export control and load consumption, an energy meter (DTSD1352-C/1(6)A with external CT) is needed. The energy meter and inverters are connected via daisy-chain RS485 as per standard RS485 topology. Up to 10 devices can be connected with an EyeM4 (WiFi) Dongle. The EyeM4 and an energy meter can only be connected in the first or the last inverter when inverters are connected together via daisy-chain.

Quick Commissioning Checklist

RS485 Connection

Sungrow recommends that RS485 can be connected by terminal blocks for more than one inverter.

Diagram Description: Figure 1 shows three inverters connected in series via RS485 terminal blocks (A1, B1, PE). A plant monitoring station (Logger) is connected to the RS485 bus.

Optional: Ensure the termination resistors (120 Ohm) are enabled ON (SW1) at each end of the RS485 in the inverter line (only the first and the last inverter) when more than 15 inverters are connected.

Diagram Description: Figure 2 shows inverters with termination resistors (SW1) set to ON. The first and last inverters in a chain of more than 15 are highlighted. A plant monitoring station (Logger) is shown.

Energy Meter to Inverter Connection

The site electrician will need to calculate the CT ratio required as per the installation. The default Modbus address is 1 and the secondary current of the CT should be 5A. Please refer to the Meter Selection Guide for reference.

Where RJ45 is used, the corresponding pinouts to RJ45 are Pin 3 (White-green) to RS485- B and Pin 6 (Green) to RS485+ A.

Diagram Description: Figure 3 illustrates the meter's RS485 pin-outs. A Shielded Ethernet cable (RJ45 connector) is shown with pinouts. Pin 3 (White-green) connects to RS485- B, and Pin 6 (Green) connects to RS485+ A. A table lists cable colors and their corresponding RS485 connections.

Terminal 21 connects to the Green cable (RS485+ A) and terminal 22 connects to the White/Green cable (RS485- B) on the DTSD1352 energy meter side.

Diagram Description: Figure 4 shows the energy meter (DTSD1352) terminals. Terminal 21 connects to the green cable (RS485+ A), and terminal 22 connects to the white/green cable (RS485- B). A photo shows the meter's terminal block with labeled connections.
