NOTICE
Loss of plant data possible!
Only perform a manual firmware update when the PV plant is not in operation
(e.g. during the night). Otherwise, losses may occur during the recording of the plant data.
NOTICE
Loss of data 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.
Using a separate SD card for firmware updates
Use a separate SD card for firmware updates, which contains only the update files for the
Sunny WebBox. If there are update files on the external SD card, exporting XML and CSV
files is deactivated.
Saving only one update file in the "UPDATE" folder.
The "UPDATE" folder may only ever contain one update file. If there is more than one
update file in the "UPDATE" folder, the firmware will not be updated.
