Works well, but in basic mode on Linux without an interface.
The parcel with the inverter arrived on time. It works perfectly. The monitoring and management of the parameters of the EATON ELLIPSE ECO 650 USB UPS is difficult to set up, and does not work well. If I leave the USB plug connected to the computer, it causes the computer to restart automatically. So I unplug the USB from the inverter, and only plug it in when I need to.
