The SCB3000 is designed and tested in strict accordance with relevant safety regulations. However, as electrical and
electronic equipment, the following safety instructions must be observed during installation and maintenance, and
improper operation will cause serious injury and property damage to the operator and a third party.
• The SCB3000 must be installed and maintained by professionals in accordance with local standards and regulations.
• When installing and maintaining the SCB3000, power must be disconnected from the SCB3000 to prevent electric
shock.
• During operation, do not touch any live parts of the SCB3000, such as its internal components and cables, to avoid
electric shock.
• Before replacing any components within the SCB3000, power must be disconnected from the SCB3000 and the newly
replaced components must be ensured to meet the requirements for use of the SCB3000, and GOODWE will not be
liable for any personal harms or warranty claims arising from noncompliance with this instruction.
• When the SCB3000 is in operation, do not plug in or remove any cable.
• The SCB3000 has an internal lightning protection module installed, inside which the PE is connected to ground when
installing the SCB3000.
• Ensure that the AC input voltage and current are matched with the voltage and current ratings of SCB3000, otherwise
the components could be damaged or not functioning properly, and GOODWE will not be liable for any responsibilities
or warranty claims arising from this mismatch.

for the port aggregation, data acquisition and storage, as well as centralized monitoring and
maintenance of inverters, environment monitors and instrumentations in photovoltaic power
generation systems.
SCB3000 model description:
SCB3000 includes the SCB3000P00 and SCB3000P01. The SCB3000 is the name of the series of
photovoltaic communication boxes; P means that the local communication mode is PLC2.0; 00
means that the cloud communication method supports LAN; 01 means that the cloud
communication method supports LAN and optical fibre. In this manual, the SCB3000P00 and
SCB3000P01 models are both referred to as the SCB3000.
Flexible networking:
Communication with inverters supported via PLC or RS485.
Communication with the server available via Ethernet, fiber optics, etc.
Note: When the SCB3000 uses PLC communication, it can only communicate with inverters supporting PLC2.0.
Currently, inverters equipped with PLC2.0 function include the HT and SMT series. For details, please contact
the Goodwe after-sales service centre.

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.
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 "RELOAD" 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.
11 12

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 "RELOAD" 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.
(b) Right-click “Network" and select "Properties".
(c) Click "Change adapter settings".
The following popup dialog box is displayed:
(d) In the local connection popup dialog box, right-click "Local connection" and click "Properties".
13 14

(e) Double-click "Internet Protocol Version 4 (TCP/IPv4)" to show the "Internet Protocol Version 4
(TCP/IPv4)" popup dialog box, and set up the dialog box according to the requirements below.
The default IP address of the SCB3000 is 192.168.1.200. To keep the 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且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.
Custom is used for parameter configuration and Modbus protocol for normal
communication.
The machine is set to "Custom" in the factory by default, and the following protocol
showed in grey is the one that is currently used. After switching protocols, ProMate waits
about 1 minute to proceed.
Note: Select the GOODWE custom protocol first to configure the BOX No and inverter address, then switch to
the Modbus protocol for communications after all parameters have been configured.
