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.
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.
Suitable USB
flash drives
Due to the variety of USB flash drives available on the market, it cannot be guaranteed that
every USB flash drive will be detected by the inverter.
Fronius recommends that only certified USB flash drives suitable for building sites are used
(look out for the USB-IF logo).
The inverter supports USB flash drives with the following file systems:
- FAT12
- FAT16
- FAT32
Fronius recommends that the USB flash drives employed should only be used for record-
ing logging data or updating the inverter software. The USB flash drives should not contain
any other data.
