8 Cluster Controller System
8.1 Procedure when Replacing Different Devices
8.2 Replacing the Inverter with Speedwire in Cluster Controller
Procedure:
• Replacing an Inverter in Cluster Controller
• Replacing an Inverter in the Sunny Portal System
Replacing an Inverter in Cluster Controller
1. Read the serial number of the inverter to be replaced off the type label and write it down.
2. Determine the energy yield of the inverter to be replaced:
• Log into the user interface of the Cluster Controller.
• Select the inverter to be replaced in the system tree.
• Select Overview and read off and write down the value in the Total yield row.
3. If you are using Sunny Portal, you must send all data saved to the inverter and to the Cluster Controller to
Sunny Portal prior to replacing the inverter.
• Select the Cluster Controller in the system tree.
• Select Settings > Sunny Portal > Basic settings > [Edit].
• Select Every 15 minutes in the drop-down list Upload frequency.
• Select [Save]. The saving process may take a few minutes.
• Select [Logout] and wait 20 minutes. This will ensure that that the data transmission between the
Cluster Controller and Sunny Portal has been terminated.
• Log into the user interface of the Cluster Controller and check whether the upload to Sunny Portal was successful.
Select the Cluster Controller in the system tree and select Settings > Sunny Portal > Last successful upload.
4. Decommission the inverter to be replaced (see the inverter manual).
5. If you retrofit the new inverter with Speedwire/Webconnect communication, install the Speedwire/Webconnect
interface in the inverter and commission (see the Speedwire/Webconnect interface manual).
6. If BLUETOOTH communication is integrated in the new inverter, turn the rotary switch on the inverter for the NetID
with a screwdriver (blade width 2.5 mm) to 0 (see the inverter manual). This deactivates the BLUETOOTH function.
7. Commission the new inverter (see inverter manual).
8. Log into the user interface of the Cluster Controller.
☑ The new inverter is displayed with a padlock symbol in the system tree.
9. Adapt the system password to the device password of the new inverter so that you can access the new inverter:
• Select the Cluster Controller in the system tree.
• Select Settings > User rights > Access control > [Edit].
• Enter the password of the user group Installer (standard password: 1111) set up in the new inverter in the fields
Set installer password and Confirm the password.
• Enter the password of the user group User (standard password: 0000) set up in the new inverter in the fields
Set user password and Confirm the password.
• Select [Save].
☑ The Cluster Controller changes the system passwords for all approved devices in the system.
