SMA America, LLC 11 Archiving Data on an SD Card
Technical description SI4548_6048-US-TB_en-13 95
The firmware of the Sunny Island 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
•Inverter
•System
•External source
•Loads
The data saved on the SD card can be processed using common table calculation programs.
• The first 13 lines of the file are used for information (file header).
• The following data is separated by semicolons.
• Decimal places are separated by periods.
• The date format is MM/DD/YYYY
• The time format is hh:mm.
"BOOTEX.LOG" File
The file "BOOTEX.LOG" is not necessarily saved on the card, it is generated according to the
operating system used (e.g. WindowsXP or Windows2000).
Always save data
Always use the SD card to save data and events. In case of a failure SMA can thus help you
quickly.
1. In the event of a fault contact the SMA Service Line.
2. Upon agreement with the SMA Service Line, save all data from the SD card into one
folder and compress this (e.g. as ZIP file).
3. Send the compressed data via e-mail to the SMA Service Line.
