1. The Kernel SCB

1.1 General

The Kernel from Kernel Sistemi is compatible with the Solar-Log Base 2000.
Up to 60 Kernel SCBs can be connected to a single Solar-Log Base 2000.
You have to request and enter a license code before you can select and configure the Kernel SCB.
Steps for purchasing and importing a license for the Solar-Log™:

  • Go to the license portal at https://shop.solar-log.com.
  • Log on with your Enerest account.
  • After you have to enter the serial number of the Solar-Log™, a list of compatible licenses is displayed.
  • You can only select one license from the list. After the selection has been made, the web-shop payment options appear.
  • After the payment confirmation, the license is valid.

Automatic import:

  • Go to the Configuration | System | Licenses WEB menu of the Solar-Log™.
  • Click on Synchronize.
  • Now the Solar-Log™ connects to the license server and downloads all of the active licenses.

Manual import:

  • Download the license file from the License portal.
  • Go to the Configuration | System | Licenses WEB menu of the Solar-Log™.
  • Click on the plus symbol and select the license file.

After importing the license, it is activated immediately and „Installed“ is displayed.

Note

Licenses are linked to the device (serial number). The license has to be purchased again if a device has been replaced after the warranty has expired.

Note
If a Solar-Log™ with a license has a defect during the warranty period, a license can be requested for the replacement device. There are no costs involved, provided that the defective device is returned to Solar-Log GmbH.

2. Communication Setup

The Kernel SCB is connected to either the RS485A or RS485B interface of the Solar-Log Base 2000.

The wiring is done using a

  • self-made, shielded 3-wire data cable.

Connect the wires as shown in the following diagram

String Connection Box

Important note!

The following settings must be observed:

Baud rate: 19200
Data bits: 8
Parity: No
Stop bits: 1

In addition, the SW1 DIP switch must be set to “Modbus”.

2.1 Termination and Addressing of the SCB

Please refer to the manufacturer’s instructions for the configuration, termination, addressing and wiring of the

Kernel SCB from Kernel Sistemi.

3. Solar-Log™ Installation

3.1 Configuration

To configure the Solar-Log Base 2000, you need a PC/laptop that you connect to the Solar-Log Base 2000 via a network cable or a router. Please refer to the Solar-Log Base manual for the necessary settings regarding network addresses.

Activating the Kernel SCB

  • Access the web interface of the Solar-Log™.
  • Activate the Kernel SCB in the Configuration | Devices | Definition | SCB menu.

Additional Settings

After the SCB has been activated, adjustments need to be made to the additional settings in the following sections.

  • General
  • Configuration
  • Analog Channels
  • Digital Channels

General

The following points are under General:

  • Activate SCB
  • Type
  • Interface

Activate SCB

The Activate SCB button activates (or deactivates) the entire SCB logic.

Type
Select Kernel SCB under Type.

Interface
Select the interface here that the SCB(s) is connected to.

Configuration
The following configuration options are available under Configuration:

  • SCB Selection
  • Connected
  • Installation date
  • Name
  • Address (0-255)
  • Model
  • Monitoring parameters from

SCB Selection
Here the profile position of the up to 60 definable SCBs can be selected and configured.

Connected
This should be activated only after the Solar-Log Base and SCB data connection has been established and the devices communicate with each other.

In Operation
This should only be activated when the PV plant feeds into the grid.

Name
Here you enter the names of the individual SCBs. We recommend assigning unique names to ensure the correct assignments.

Address (0-255)
Enter the bus address for each SCB that was assigned to the device during the SCB configuration. We recommend starting with 1 and continuing in a consecutive and ascending order to maintain a better overview.

Model
The model of the SCB that is to be applied to this confirmation can be selected here via a pull-down menu.

Monitoring parameters from

The inverters monitoring parameters are applied by the assignment to an inverter. Several SCBs can be assigned to an inverter. This method is possible because string monitoring is not possible with central inverters and for this reason monitoring parameters are not required.

The SCB monitoring parameters can be modified in the Configuration | Notifications | Power & Failure menu.

3.2 Checking the SCB Configuration

After the SCB has been successfully installed and activated, the Solar-Log Base immediately starts to receive data from it. Go to SCB Monitor to check the installation and data. And then go to Diagnosis | Components | SCB

Monitor. Each SCB can be selected in this section from the drop-down menu in the String Overview. The measured values from all of the SCBs are displayed in the table below.

A table with the following columns is found under Measurement from (see the figure below).

  • Analog no.
  • Type
  • Value
  • Digital no.
  • Type
  • Value

The measurements themselves occur on a regular 15-second cycle. The time of the last measurement is displayed under Measurement from.

Type
The data type of the particular channel (e.g., analogue channel current, total power, internal temperature, total voltage etc.) is displayed.

Value
The last measured values of the particular channel are displayed here.
