LAN Network port

LAN SEC1000S uses this port when accessing a network cable;The access point is as shown in the “NET” position in the figure above.
It is recommended to use network cables better than Super Five Type. After wiring, use the fire-proof mud to seal the port, to ensure its protective performance.

Communication Port

Descriptions of internal communication ports of SEC1000S are as following

Port	Description
POWER	DC Power Input (Occupied)
NET	Ethernet Interface
DI	DRED or RCR functional interface
NC	reserve
COM1	485 interface1 with Inverter
COM2	485 interface2 with Inverter

SEC1000S Grid Connection Diagram

Note: 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 firmware of ET or BT applied in this solution, with DSP version 01 or newer and ARM version 09 or newer. The firmware version of SEC1000S designated for inverter paralleling application should be 01 or newer..

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 flow prevention, etc. The corresponding parameters of the inverter are acquired and set through the software ProMate installed in computer for monitoring and configuring SEC1000S. ProMate is a kind of software that can configure Ezlogger Pro, SEC1000S etc. It can modify the network IP address of Ezlogger Pro and SEC1000S, configure the number of connected inverters, time setting, RCR, DRED function, configuration and on-site debugging. First, the user need to install “ProMate” in the computer by downloading ProMate from Internet (http://www.goodwe-power.com/files/ProMate.rar), Please access to the website to download the program and competethe installation. If the user needs to use ProMate software to configure 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 modified. 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 Configuration” 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.

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.

PV Master configuration for paralleling application (inverter)

You should set communication address for every inverter in the paralleling system, and the address should be different 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:

Note: When replacing the meter, all 3 groups of CTs need to be short- circuited.
