The buffer memory can store a maximum of 6 logging points. Data is logged only during
inverter operation (power greater than 0 W). The logging interval is set to 30 minutes. This
results in a time span of 3 hours for recording data in the buffer memory.
When the buffer memory is full, the oldest data in the buffer memory is written over with
the new data.
IMPORTANT! The buffer memory requires a constant power supply.
If there is an AC power outage during operation, all data in the buffer memory is lost. The
automatic night switch-off must be deactivated so that data is not lost at night (set “Night
Mode” to ON – see the Operating Instructions for Datamanager 2.0 and the sections “Set-
ting and Displaying Menu Items,” “Displaying and setting parameters in the ‘DATCOM’
menu item”).
Suitable USB
Sticks
Due to the number of USB sticks on the market, we cannot guarantee that every USB stick
will be recognized by the inverter.
Fronius recommends using only certified, industrial USB sticks (look for the USB-IF logo).
The inverter supports USB sticks using the following file systems:
- FAT12
- FAT16
- FAT32
Fronius recommends that the USB stick only be used for recording logging data or for up-
dating the inverter software. USB sticks should not contain any other data.

dating Inverter
Software
The USB stick can be used to help end customers update inverter software via the USB
menu item in the SETUP menu item: the update file is first saved on the USB stick and then
transferred to the inverter. The update file must be saved in the USB stick root directory.
USB symbol on the inverter display, e.g., in the "NOW" display mode:
When the inverter recognizes a USB stick,
the USB symbol will appear at the top right
of the display.
When inserting the USB stick, make sure
that the USB symbol is displayed (it may
also be flashing).
NOTE! Please be aware that in outdoor applications the USB stick may only func-
tion in a limited temperature range. Make sure, for example, that the USB stick
will also function at low temperatures for outdoor applications.
