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.

3.3 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.
