11 Data Storage on SD Memory Card
The Sunny Island can store firmware, parameters and measured data on a SD memory card which
must be FAT-16-formatted and may have a max. size of 2 GB (possible storage sizes are 32/64/
128/256/512 MB and 1 GB and 2 GB). Use the supplied SD memory card only for the
Sunny Island. Do not save any multimedia files on the SD memory card.
File names are saved in 8.3 format and files with other designations are ignored.
Once you have inserted the SD memory card in the slot on your PC, you can search the corresponding
drive in your Explorer (example here: Microsoft Windows). The following data is present on this drive
(here E:):
Example of a format
A valid 8.3 format is, for example, "M1111LOG.DAT".
8.3 is the "old" MS-DOS format with a file name that has a maximum of eight figures before and
three figures after the dot.
Type of memory card
SMA recommends the use of a Transcend SD memory card.
If you use a memory card from another manufacturer, check whether the card is FAT-16
formatted. If necessary, format the card. Be aware that data stored on the card will be lost.
Using memory cards in the off-grid system
If you combine the Sunny Island inverters in one off-grid system, use one SD memory card
always only for one type of Sunny Island (SI 4548-US-10 / 5048U / 6048-US-10). This will
ensure optimum functioning of the off-grid system.
• Make a note of the type of the Sunny Island used on the SD memory card after the first
data recording.
• Only insert this SD memory card into this type of Sunny Island.
