The buffer memory can store a maximum of six logging points. Data is only logged while
the inverter is running (output greater than 0 W). The logging interval determines the time
period over which data is stored, e.g.:
When the buffer memory is full, the oldest data in the memory will be overwritten by the
next batch of data.
IMPORTANT!
The buffer memory requires a permanent power supply.
If there is a power failure while the inverter is in operation, all the data in the buffer memory
will be lost. To avoid losing data during the night, the automatic night switch-off facility must
be deactivated (switch the 'Night Mode' setup parameter to ON - see the section 'Setting
and displaying the menu items', 'Viewing and adjusting 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.

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.
