8.2 Detecting Devices
All devices (i.e., inverters) can be detected at once. If you later wish to add additional devices to the
PV plant, you can detect them using the Sunny WebBox.
Before beginning detection, the communication mode of the PV plant has to be set (see page 60).
1. Select "Plant > Detection" in the user interface.
☑ The "Plant detection" page opens.
2. In the "Total number of devices to be detected" field, you can enter the number of devices
connected to the Sunny WebBox.
3. Select [Start detection].
☑ The Sunny WebBox starts detecting all inverters and displays its progress. Once all devices
have been detected, the Sunny WebBox displays "### Device detection finished ###".
4. Select [OK].
☑ The "Plant > Devices" page is displayed. The devices have been detected.
8.3 Parameterizing Devices
1. On the Sunny WebBox start page, log in as installer.
2. Select "Plant > Devices" in the user interface.
3. Select a device in the device view or structural view.
4. Select the "Parameters" tab.
☑ The Sunny WebBox lists all the parameters that can be changed on the selected device.
Re-detecting devices after changes to the PV plant
Devices will need to be re-detected if you:
• Exchange devices in your PV plant.
• Remove devices from your PV plant.
• Add devices to your PV plant.
Detection of a PV plant may take several minutes
Depending on the number of devices in your PV plant, the detection process may vary in
duration. If the Sunny WebBox does not signal any progress for more than three minutes,
cancel the search process. To do so, click the [Cancel] button. Check that all devices are
connected properly to your plant and repeat the detection.
The displayed parameters depend on the selected device
The displayed parameters depend on the device you selected and can vary significantly
between the product ranges (e.g. Sunny Boy and Sunny Central).
