Note:
1. The system supports up to 10 inverters, please distribute them equally to each COM port.
2. No separate Smart Meter is required in inverter paralleling system along with SEC1000S deployed. This solution
is only applicable to the paralleling of on-grid side not to back-up side. There are special requirements on the
version of rmware of ET, ET PLUS+ or BT applied in this solution, with DSP version 01 or newer and ARM version
09 or newer. The rmware version of SEC1000S designated for inverter paralleling application should be 01 or
newer.

3.3.5 Main functions of SEC1000S
In the Grid Connection Diagram as shown in 3.3.4( quantity of Inverter can be more than one),
SEC1000S will have the functions of Active Power Regulation, and Back ow prevention, etc. The
corresponding parameters of the inverter are acquired and set through the software ProMate
installed in computer for monitoring and conguring SEC1000S. ProMate is a kind of software that
can congure Ezlogger Pro, SEC1000S etc. It can modify the network IP address of Ezlogger Pro
and SEC1000S, congure the number of connected inverters, time setting, RCR, DRED function,
conguration and on-site debugging. First, the user need to install "ProMate" in the computer by
downloading ProMate from Internet (https://en.goodwe.com/), Please access to the website to
download the program and competethe installation. If the user needs to use ProMate software to
congure SEC1000S, it needs to be set in dynamic IP(DHCP) or static IP according to the network
connection mode.
(1)If the user is in the dynamic IP mode, he/she only needs to connect the SEC1000S NET port to the
Router LAN port with the network cable to connect to the network, namely plug and play.
(2)If the user has a static IP, it is necessary to switch SEC1000S to the static IP mode. That is, press
the Reload key for about 10 seconds to reset and restart SEC1000S, About 10 seconds after pressing
the Reload button, the LED lights on the SEC1000S internal EzLogger Pro Panel will blink from right
to left and reset and restart.
After restart, SEC1000S will be switched to static IP mode(default IP:192.168.1.200), then use cables
to connect SEC1000S“NET” port to the Ethernet port of the computer.At the same time, the IP
address of the computer needs to be modied. The IP address and the default gateway should be
set at 192.168.1.xxx segment (1 ≤XXX ≤250 and XXX ≠200). For example, the IP address can be set
as 192.168.1.100 and the default gateway as 192.168.1.254.
The interface of Promate is as follows:
On “COM Conguration” part, you should enter the number of inverter connected to each
communication port of SEC1000S. For example, you should enter “3” if there are 3 pieces of inverters
communicate to COM1, enter “2” if there are 2 pieces of inverters communicate to COM2.

3.3.5.1 SEC1000S Anti Reverse Current Function
On “DRED & ARCB Setting”part, enter total capacity of the paralleling system and ratio of CT
(external) and power limit into grid.
Note: the above steps are mandatory to set up the whole system.
Please check the option "Export Enable" if you want to apply export power limit function in your
system.with this function enabled, you can monitor real-time data of grid connection such as output
active power, output current, and output voltage.
3.3.5.2 PV Master conguration for paralleling application (inverter)
You should set communication address for every inverter in the paralleling system, and the address
should be dierent from each other. For example, you may set the address for each inverter from 1 to
10 if there are 10 inverters in the paralleling system. The ID of inverter connected to the communication
port should not be duplicate. To monitoring the whole system, all inverters should be registered under
the same power plant on GoodWe monitoring platform SEMS Portal.

4 Troubleshooting
If the external CT current is connected in the wrong direction, please reconnect it.
Take the reversed CT current connection of B + and B- as an example to introduce the correcting
method, as shown below:
1.B+ and B- connected
reversed
Note: When replacing the meter, all 3 groups of CTs need to be short-circuited.
2.Add a cable between B+ and
B- to short-circuit them
3.Correct connection of
B+ and B-
