2 Installation Instructions and Warnings
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.

3 Product Introduction
3.1 Product Overview
The SCB3000 is used in photovoltaic power generation systems to integrate data collectors,
allowing 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 bre. 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, ber optics, etc.will not be liable for any
responsibilities or warranty claims arising from this mismatch.
Notice: 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 Congurations
ProMate is a software released by us for the conguration of the SCB3000 functions, it enables the
modication of the network IP address of the SCB3000, the conguration of the number of port-
connected inverters, time settings, RCR and DRED feature conguration, eld debugging and more.
5.2.1 Connecting to the Master Computer Software
If the user wants to congure 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 congure 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
conguration is complete, disconnect the computer from the router.
Notice: If the SCB3000 is set to static IP mode, you need to switch to dynamic IP mode before you can congure
it using dynamic IP connection. Press and hold the "RELOAD" button for about 4 seconds, this will make the LED
signal indicators ash 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:
Notice: SCB3000 is set to dynamic IP mode by default, you need to switch the SCB3000 to static IP mode rst by
pressing and holding the "RELOAD" button for about 10 seconds, this will make the LED signal indicators of the
SCB3000 ash 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 congure 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 nd the methods on the Internet that can be used to modify the IP
addresses of computers running different operating systems.
13
(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".
(d) In the local connection popup dialog box, right-click "Local connection" and click "Properties".
14
The following popup dialog box is displayed:
(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 and XXX≠200).
For example: The IP address can be set to 192.168.1.100 and the default gateway 192.168.1.254.
15
Click the "Connect" button in ProMate, when it shows that the connection is successful, ProMate is
connected to the SCB3000 successfully.
Notice: 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 congure 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 Congurations (for PLC communication with the inverter)
When the connection to ProMate is successful, parameter congurations 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 conguration 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.
16
Notice: Select the GOODWE custom protocol rst to congure the BOX No and inverter address, then switch to the
Modbus protocol for communications after all parameters have been congured.
(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.
Notice: The Device Count and Box No are required, the devices will not function properly if either eld is not lled in.
As shown below: When nished setting the Device Count and the Box No, you can click the "Read"
button to see if the settings are successful.
17
(c) Inverter Address Conguration
Connecting the SCB3000 to the inverter requires the Modbus address to be congured, with the option
of one click and manual operation available for the inverter address conguration.
As shown below: Click the "One key cong" button, and the software randomly assigns the inverter
address.
As shown below: Click the "Set" button to see if the conguration is successful.
