5.2 Master Computer Operations & Parameter Configurations
ProMate is a software released by us for the configuration of the SCB3000 functions, it
enables the modification of the network IP address of the SCB3000, the configuration
of the number of port-connected inverters, time settings, RCR and DRED feature
configuration, field debugging and more.
Please download the ProMate app at https://en.goodwe.com/.
5.2.1 Connecting to the Master Computer Software
If the user wants to configure the SCB3000 using ProMate software, the master
computer needs to be connected in either dynamic IP (DHCP) or static IP according to
the way the network is connected.
1. SCB3000 dynamic IP address connection:
SCB3000 is set to dynamic IP mode by default, and the network connection is simply
made by connecting the SCB3000 NET port to the router LAN port with the network
cable, which is plug and play. To configure the SCB3000, connect your computer to the
router with a network cable, and launch the ProMate software in which you can click
"Scan" to complete the connection successfully. When the configuration is complete,
disconnect the computer from the router.
Note: If the SCB3000 is set to static IP mode, you need to switch to dynamic IP mode before you can
configure it using dynamic IP connection. Press and hold the "RESET" button for about 4 seconds, this will
make the LED signal indicators flash from right to left, indicating a completed reset and restart, after
which the SCB3000 will be switched to static IP mode.

2. SCB3000 static IP address connection:
Note: SCB3000 is set to dynamic IP mode by default, you need to switch the SCB3000 to static IP
mode first by pressing and holding the "RESET" button for about 10 seconds, this will make the LED
signal indicators of the SCB3000 flash from right to left, indicating a completed reset and restart,
after which the SCB3000 will be switched to static IP mode (the default IP address is 192.168.1.200).
The user needs to set the computer to static IP mode, and configure the computer's IP address and
the SCB3000's IP address in the same network segment. The steps are as follows (using Windows 7
OS as an example). Users can find the methods on the Internet that can be used to modify the IP
addresses of computers running different operating systems.
(a) Use a network cable to connect the "NET" of the SCB3000 to the Computer's Ethernet port.

computer and SCB3000 in the same network segment, the "IP address" and "Default
Gateway" should be set at the 192.168.1.XXX segment (1≤XXX≤250 and XXX≠200).
For example: The IP address can be set to 192.168.1.100 and the default gateway
192.168.1.254.
Click the "Connect" button in ProMate, when it shows that the connection is
successful, ProMate is connected to the SCB3000 successfully.
Note: If there is only one Box-type substation on the customer site, and the data is uploaded to GOODWE
servers, there is no need to configure the box number and address through ProMate, simply connect
ProMate, click to get the inverter list to see if the inverter is all online. If there are multiple box Box-type
substations onsite, refer to 5.2.2 for setup.
5.2.2 Parameter Configurations (for PLC communication with the inverter)
When the connection to ProMate is successful, parameter configurations can be
made on the SCB3000 and the inverter to which it is connected.
(a) Choose Protocol
Click the "Ezlogger Pro" button and select the protocol in the following popup.

(b) Settings of Device Count and Box No
Enter numbers for both "Device Count" and "Box No".
For "Device Count", enter the number of inverters actually connected to the current SCB3000.
The "Box No" is used to identify the Box-type substations onsite. (For example, if there are
multiple SCB3000s in use onsite, they must be corresponding to different box numbers) As
shown below: the number of inverters connected to the SCB3000 on-site is 3, so the "Device
Count" of 3 in entered.
Note: The Device Count and Box No are required, the devices will not function properly if either field is
not filled in.
As shown below: When finished setting the Device Count and the Box No, you can click
the "Read" button to see if the settings are successful.
As shown below: Click the "Set" button to see if the configuration is successful.
(c) Inverter Address Configuration
Connecting the SCB3000 to the inverter requires the Modbus address to be
configured, with the option of one click and manual operation available for the
inverter address configuration.
As shown below: Click the "One key config" button, and the software randomly
assigns the inverter address.
