SMA America, LLC Archiving Data on an SD Card
Technical Description SI5048U-TUS121440 93
The files on the SD card have the following meanings:
The Sunny Island's firmware expects device-specific data in the main directory of the SD card. This
data includes a new firmware, parameters and measuring data.
The Sunny Island uses the SD card for saving and loading device parameters.
In addition, the Sunny Island supports the acquisition of measurement data on the 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 two different types of log data:
• Measurement data (are saved cyclically)
• Events and errors (are only saved when they occur)
The Sunny Island supports the acquisition of measurement data with data from the fields:
•Battery
•Inverters
•System
•External source
