Your other comment got downvoted to death (not by me) so I can't reply to it, so I'm replying here. Sorry the downvoting happened; your comment wasn't incorrect. You're right that inverters with zero connectivity whatsoever are not banned; my comment was overly broad. That said...

The ban covers any inverter with any wireless communication whatsoever. Bluetooth is specifically called out, despite necessarily being local-only and not enabling an internet connection.

I suppose you could make the argument that with Bluetooth, the app that communicates with it has internet access and thus it's the same thing. However:

The ban does not cover a power inverter with no integrated comms, but has a serial port into which is plugged a "sold separately" wifi dongle. Neither does the ban cover an inverter with an ethernet port. It covers solely wireless communication.
