USB Stick as a Data Logger and for Updating Invert-
er Software
USB flash drive
as a datalogger
If a USB flash drive is connected to the USB A socket it can function as a datalogger for
an inverter.
The logging data stored on the USB flash drive can be viewed at any time in third-party
programmes (e.g Microsoft® Excel) using the CSV file logged at the same time.
Older versions of Excel (before Excel 2007) are limited to a maximum of 65,536 rows.
Data on the USB
stick
If the USB stick is being used as a data logger, three files will be created automatically:
- FRONIUS.sys system file:
This file stores information from the inverter that is irrelevant to the customer. The file
must not be deleted separately. Only delete all of the files (sys, fld, csv) at one time.
- DALO.fld log file:
A log file for reading the data in the Fronius Solar.access software.
Further details on the Fronius Solar.access software can be found in the "DATCOM
Details" operating instructions at http://www.fronius.com
- DATA.csv log file:
A log file for reading the data in a spreadsheet program (e.g.: Microsoft® Excel)
Data structure on the USB stick
(1) USB root directory
(2) Fronius inverters (Fronius Galvo,
Fronius Symo, Fronius Primo or
Fronius Eco)
(3) Inverter number - can be set in the
Setup menu under DATCOM
If there are several inverters with the same
inverter number, the three files will be sa-
ved in the same folder. A digit is added to
the file name as a suffix (e.g.: DALO_02.fld)
