14.1 Information on the SD Card
In order to ensure the proper functioning of the SD card, use the SD cards available from
SMA Solar Technology AG. Compatibility with all SD cards available on the market cannot be
guaranteed. The Sunny WebBox does not support SD cards with storage capacities of more than
2 GB or SDHC cards.
Only use SD cards which have been formatted with the FAT16 file system. If necessary, use the
computer to reformat the SD card.
