Performing Updates for the Cluster Controller and the Inverters
You have the option of performing updates for the Cluster Controller and the inverters in the system
(see the Cluster Controller user manual). You can perform the updates automatically or manually.
The update source can be the SMA Update Portal or a USB data carrier with update files
downloaded from the Internet. Alternatively, you can also upload the update files directly from the
computer via the user interface of the Cluster Controller.
