1 Introduction
This quick guide is showing how to commission the SG30/50/110CX inverters and it
is to be read in conjunction with the Sungrow’s User Manuals.
Where more than one inverter, or an energy meter installed, the commissioning and
iSolarCloud connection is done via a Logger1000(Up to 30 devices) and EyeM4(Up to
10 devices).
For export control and load consumption, an energy meter (DTSD1352-C/1(6)A with
external CT) needed to be connected.
All of the components are connected via daisy-chain as per standard RS485 topology.

2 RS485 Connections
2.1 Inverter Connection (Daisy Chain)
Recommend that RS485 can be connected by terminal blocks.
Please note SG15/20KTL-MT inverters connection is different as SG30/50/110CX inverters.
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.

2.2 Energy Meter Connection
The site electrician will need to calculate the CT ratio required as per the installation.
Default Modbus address is 1 and the secondary current of CT should be 5A. Please
refer Meter Selection Guide for reference.
The corresponding pinouts to RJ45 are Pin 3 (White-green) to RS485- B and Pin 6
(Green) to RS485+ A:
DTSD1352 energy meter connection:
•Terminal 21 = RS485+ A (Green)
•Terminal 22 = RS485- B (White/Green)

DTSU666 energy meter connection:
•Terminal 24 = RS485+ A (Green)
•Terminal 25 = RS485- B (White/Green)
Logger1000 connection: Connect to Logger1000 via the RS485 cable from the
energy meter on RS485 port A2 and B2 if it has not been used.
EyeM4 connection: Connect the energy meter RS485 to A2/B2 (RS485-2 Interface)
terminals in the inverter that has the EyeM4 dongle.
Note: the Logger1000 and EyeM4 must be updated to the latest firmware to support
the DTSU666 energy meter. To upgrade the Logger1000/ EyeM4, refer to th Part 5 of
this document.

2.3 Connection to Logger1000
Connect the RS485 comms from the inverter(s) via A1/B1 and the energy meter via
A2/B2 (can be connect to A3/B3 if A2/B2 is occupied by inverters) to the Logger1000
as an example.
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 COM2on the portal.

2.4 Connection via EyeM4
Connect the energy meter RS485 to A2/B2 (RS485-2 Interface) terminals in the
inverter that has the EyeM4 dongle. (Communication PCB varies between inverter
models –ensure to use A2/B2).
Figure 1.4.1 RS485 connections in the inverter (SG30/50CX and SG110CX)
Important: Enable RS485 Port for Inverter via iSolarCloud App
Access the iSolarCloud App via Bluetooth, once clicking Bluetooth, you will be
prompted to select the Bluetooth device (Inverter SN). Click on the SN you wish to
connect to and then login to the inverter. Please put in “admin” as the account and the
password (pw8888).
Click "More" > "Settings" > “Operation Parameters” > “Other Parameters” > Enable”
transparent transmission via standby RS485 port.
