USB Stick as a Data Logger and for Updating Invert-
er Software
USB stick as a
data logger
A USB stick connected to the USB A socket can act as a data logger for an inverter.
Logging data saved to the USB stick can at any time
- be imported into the Fronius Solar.access software via the included FLD file,
- be viewed directly in third-party applications (e.g., Microsoft® Excel) via the included
CSV file.
Older Excel versions (up to Excel 2007) have a row limit of 65536.
Data on the USB
stick
If a USB stick is used as a data logger, three files are automatically created:
- System file *.sys:
This file saves information from the inverter that is irrelevant to the customer. The file
must not be deleted individually. Only delete all files together (sys, fld, csv).
- Log file TLxxx_yy.fld (xxx = IG number, yy = a serial 2-digit number):
Log file for reading out data in Fronius Solar.access.
You can find additional information on the Fronius Solar.access Software in the "DAT-
COM Detail" operating instructions at http://www.fronius.com
- Log file TLxxx_yy.csv (xxx = IG number, yy = a serial 2-digit number):
A log file for reading out data in a spreadsheet program (e.g., Microsoft® Excel)
