USB Stick as a Data Logger and for Updating In-
verter 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
stick
If the USB stick 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 custom-
er. The file must not be deleted individually. 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 "DATCOM 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® Ex-
cel)
Data structure on the USB stick
(1) USB root directory
(2) Fronius inverter (Fronius Galvo,
Fronius Symo, Fronius Primo, or
Fronius Eco)
(3) Inverter number – can be set in
the setup menu under DATCOM
If multiple inverters exist with the
same inverter number, the three files
are saved in the same folder. A number
is appended to the file name (e.g.,
DALO_02.fld)
63
