8.3 Replacing the Cluster Controller
Procedure:
• Replacing the Cluster Controller
• Replacing the Cluster Controller in the Sunny Portal System
Replacing the Cluster Controller
1. If the Cluster Controller to be replaced still allows it, safe the device configuration of the Cluster Controller:
• Log into the user interface of the Cluster Controller.
• Select the Cluster Controller in the system tree.
• Select Update and save > Device Configuration and [Save device configuration].
• If required, change the save location and the file name for the save file and select [Save].
☑ The device configuration is downloaded and saved.
2. Commission the new Cluster Controller (see the Cluster Controller installation manual).
4. In case you have saved the device configuration of the Cluster Controller to be replaced, transfer the device
configuration to the new Cluster Controller:
• Log into the user interface of the Cluster Controller.
• Select the Cluster Controller in the system tree.
• Select Update and save > Device Configuration and then select [Browse] in the field Restore device
configuration (*.bak).
☑ The file selection window opens.
• Select the desired configuration file and select [Open].
☑ The file name of the selected configuration file is displayed in the Restore device configuration (*.bak).
• Select [Submit].
☑ The configuration file is uploaded and the device configuration is restored. The Cluster Controller restarts.
No combination of Cluster Controller and Sunny WebBox in one Sunny Portal system possible
In a Sunny Portal system, the Cluster Controller may not be used in combination with the Sunny WebBox.
• If there is already a Sunny WebBox in the Sunny Portal system where you want to integrate the new
Cluster Controller, you must delete the Sunny WebBox from the Sunny Portal system before registering the new
Cluster Controller (see user manual of the Cluster Controller in Sunny Portal). The PV system identifier of the
Sunny Portal system can be read off in Sunny Portal under Configuration > PV System Data and then be
inserted in the Cluster Controller as described in this section.
Restoring the device configuration of the Cluster Controller: observe the firmware version
Only configuration files with a firmware version that is the same as or older than that of the new Cluster Controller
can be used to restore the device configuration of the Cluster Controller.

Danger to life due to electric shock
Lethal voltages are present at the connection point of the utility grid.
• Disconnect the connection point from the utility grid using the separator (e.g. circuit breaker).
• Remove the three-pole plug of the top-hat rail power supply unit from terminal X1 of the Cluster Controller.
• Disassemble the Cluster Controller to be replaced (see the Cluster Controller installation manual).
