11 Archiving Data on an MMC/SD Card
The Sunny Island 5048 can save firmware, parameters and measuring data on a
multimedia card (MMC/SD card) that must be FAT16-formatted and may have a
maximum capacity of 2 GB (possible memory capacities are 32/64/128/256/512
MB as well as 1 GB and 2 GB). File names are saved in 8.3 format and files with other
names are ignored.
The firmware of the Sunny Island 5048 expects device-specific data in the main
directory of the MMC/SD card. This data includes a new firmware version, parameters
and measuring data. The firmware ignores non-device-specific data in the main
directory.
The Sunny Island 5048 uses the MMC/SD card for saving and loading device
parameters.
In addition, the Sunny Island 5048 supports the acquisition and archiving of measuring
data on the MMC/SD card. It saves this data in a special file. This contains, among
other things, a header, time stamp, date and data type. There are three types of log
data:
•
Measuring data (are saved cyclically)
•
Events and errors (are only saved when they occur)
The Sunny Island 5048 supports the acquisition of measurement data with data from
the following areas:
•
Battery
•
Inverter
•
System
•
External source
•
Loads
Such data is recorded over a period of up to four weeks. At the end of four weeks, the
oldest data is successively discarded.
A valid 8.3 format is, for example, "M1LOG.DAT".
8.3 is the "old" MS-DOS format with a file name that has max. 8 figures before
and 3 figures after the dot.
SMA
Technologie AG recommends using MMC/SD cards made by Transcend.
