It banned all foreign made solar inverters i.e. all solar inverters.

That’s true. China dominates globally but I found that the US installed European and Japanese models. There is a big supply chain concern and set of reviews happening all across the entire government sector. Energy is a national security concern. [1]

It's bad policy.

If one is trying to attack the threat you claim, one might ban all internet capable inverters.

To ban all, even fully offline ones, means the threat you describe is an excuse.

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.

"connected power inverters produced in foreign countries"

I think home devices that phone somebody-elses-home are a cancer anyway.
