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
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.
USB stick for up-
dating the invert-
er software With the help of the USB stick, end customers can also update the inverter software via the
USB item on the SETUP menu: the update file is first saved to the USB stick, from where
it is then transferred to the inverter. The update file must be saved in the root directory on
the USB stick.
USB symbol on the inverter display, e.g. in display mode 'NOW':
If the inverter detects a USB flash drive,
the USB symbol will appear in the top right
corner of the display.
When inserting a USB flash drive, check
whether the USB symbol is displayed (it
may also flash).
NOTE! Please note for outdoor applications that conventional USB flash drives
are often only guaranteed to work within a restricted temperature range. For out-
door applications ensure that the USB flash drive also functions, for example, at
low temperatures.
