The message “an error occurred during FTP upload” indicates a server error. It relates to an external event – the Sunny WebBox or the SMA Cluster Controller do not themselves exhibit a disturbance, rather they just relay the server error to Sunny Portal.
The exact form of the error can be determined via the FTP error code. For example, the login data can be incorrect or the FTP server is not available.
Specialist websites that list descriptions of the disturbances can be found on the internet using the search term “FTP error codes”.

Further corrective measures:
- Wait for a new data transmission
- Check the availability of the FTP server
- If the error occurs continuously or if the FTP error message indicates defective data:
- – Check whether there are any defective or corrupt files in the data logger
– contact the installer
– Delete the Sunny Portal buffer, as described e. g. in the Sunny WebBox user manual
