1. Introduction

This quick guide is to be read in conjunction with the Sungrow’s User Manuals and 3-

phase KTL series inverters as example for demonstration.

When more than one inverter is installed, all the commissioning is done via a

Logger1000. All the components are connected via daisy-chain RS485 asper standard

RS485 topology.

For export control and load consumption, a 3-phase energy meter needs 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).

2. RS485 Connections

2.1 Inverter Connection (Daisy Chain)

The RS485 is connected by RJ45 connector at the inverter end and terminated cable

at the logger end.

Connect the RJ45 plug to the front COM port on the inverter via the supplied shroud.

Note: Make sure to plug into the COM port on the inverter (Terminal 2). DO NOT

plug into the RS485 port (Terminal 5)

As the Sungrow KTL series inverter only has one port for COM connection, if the daisy-

chain RS485 connection is required, this can be accomplished by using a third party

RJ45 splitter.

Note: Make sure the splitter splits 8-pin cable into two 8-pin outputs. Some of the

splitters only divide 8-pin cables into two groups of 4-pin outputs which will not work.

Note: Never connect the meter to the same RS485 terminals as the inverters.

2.2 Energy Meter Connection

For supplies smaller than 80 Amps, use the DTSU666 with inbuilt CTs.

For installations where the supply is larger than 80 Amps, the electrician need to select

appropriate CT ratings. The secondary current of CT should be 5A. The CT ratios can

be set on Logger1000. 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:

On the DTSD1352 energy meter side, terminal 21 to Green cable (RS485+ A) and

terminal 22 to White / Green cable (RS485- B).

The following figures shows the meter cable connection on the energy meter.

Connect to Logger1000 via the RS485 cable from the energy meter on RS485 port A2

and B2.

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 COM2 on the portal.

3. Web Portal Setup

3.1 Access Web Portal

Use a smart device or laptop under Wi-Fi function to search for the SG********** (10

digits number) network that corresponds to the Logger1000 serial number. Connect to

the network, if a password required, use the serial number.

Open a web browser and enter IP address (11.11.11.1) to access below Logger1000

web page.

Then log in the account with the password “pw1111” via the top right corner login

button. When you log in for the first time, a help window will pop up for instruction.

3.2 Set Local Time

Navigate to ‘System Time’ under System and select Clock Source to ‘NTP’ and Time

Zone to ‘UTC+10:00’ and make sure to Save

3.3 Scan for Inverters

Navigate to ‘Device’ and click ‘Device List’ section and click ‘Auto search’. Sungrow

inverters will be automatically detected as long as they are correctly connected and

energized.

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 the device.
