NOTICE
Loss of plant data possible!
Only perform a manual firmware update when the PV plant is not in operation (e.g. at
night). Otherwise, this can lead to gaps in the recording of plant data.
NOTICE
Data loss on the SD card possible!
Do not remove the SD card while the "SD CARD" LED is flashing green or orange. This can
damage the file system of the SD card and lead to data loss. Depending on the amount of
data, the writing process can take some time.
Use a separate SD card for firmware updates
For firmware updates, use a separate SD card that contains only the update files for the
Sunny WebBox. If there are update files on the external SD card, the export of XML and
CSV files is deactivated.
Only save one update file in the "UPDATE" directory.
There should only ever be one update file in the "UPDATE" directory. If there is more than
one update file in the "UPDATE" directory, the firmware update will not take place.
