USB Stick as a Data Logger and for Updating In-
verter Software
USB flash drive
as a datalogger
If a USB flash drive is connected to the USB A socket it can function as a data-
logger for an inverter.
At any time, the logging data stored on the USB flash drive can be
-
imported into the Fronius Solar.access software using the FLD file that was
logged at the same time,
-
viewed directly in third-party programs (e.g. Microsoft® Excel) using the CSV
file logged at the same time.
Older versions (before Excel 2007) are limited to a maximum of 65,536 rows.

capacity" as well as "Buffer memory" can be found at:

Data on the USB
flash drive
If the USB flash drive 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 custom-
er. 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® Ex-
cel)
