USB Stick as a Data Logger and for Updating Invert-
er Software
USB Flash Drive
as a Data Logger
A USB flash drive connected to the USB A socket can act as a data logger for an inverter.
The logging data that is saved on the USB flash drive can be viewed directly in third-party
applications (e.g., Microsoft® Excel) at any time via the included CSV file.
Older Excel versions (up to Excel 2007) have a row limit of 65536.
Data on the USB
thumb drive
If the USB thumb drive is used as a datalogger, three files are automatically created:
- FRONIUS.sys system file:
This file saves information from the inverter that is irrelevant to the customer. The file
must not be deleted separately. Only delete all files together (sys, fld, csv).
- DALO.fld log file:
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
- DATA.csv log file:
A log file for reading out data in a spreadsheet program (e.g., Microsoft® Excel)
Data structure on the USB thumb drive
(1) USB root directory
(2) Fronius inverter (Fronius Galvo,
Fronius Symo Advanced, Fronius
Primo, or Fronius Eco)
(3) Inverter number – can be set in the
setup menu under DATCOM
If multiple inverters exist with the same in-
verter number, the three files are saved in
the same folder. A number is appended to
the file name (e.g., DALO_02.fld)
