I'm just guessing, but I imagine 1 malfunctioning unit probably wouldn't be able to raise the voltage enough to trick the other units.
OTOH, in an area with a significant number of solar installations, I can easily see them creating an isolated network segment where the voltage runs near normal and so they collectively convince each other to stay on. That could create an interesting problem of how to convince that segment to re-synchronize with the grid when it's time to re-connect.
That's why the linemen say it's not dead until it's dead and grounded. They are supposed to bond the line to ground before working on it and that bond is supposed to only be disconnected right before the line is turned back on.
But since mistakes happen, it's a good thing that home inverters won't power a dead line.
The biggest danger to linemen (and has been for a while) is id10ts wiring their portable generators in or plugging them in with a "widowmaker" (A generator chord with a male end to plug in to the wall) and not disconnecting from the grid first.
Since "scientific evidence" is very persuasive to jurors, they'll be granting new trials to the ones they haven't killed yet.
HAHAHAHAHAHAHAI crack me up!
Actually, no.
In the most extreme cases of improvisation, people have used rocks with a crystalline structure or a razor blade, a pencil, and a safety pin as a detector connected to headphones.
I was under the impression there isn't much use of AM radio in Norway.
In practice, it's a bit worse for digital. The decoders seem to lose sync easily and just go black for a bit where the analog would have given a couple frames of static and then a watchable image. If it happens frequently enough, you get a black screen and silence from digital where you would get a staticy but watchable picture on analog.
Multipath on a digital signal is a serious issue where on analog, you will actually stop noticing the ghosts after a few minutes.
On the old analog NTSC, the audio was on a subcarrier such that even if the video was an unwatchable mess, you might get decentish audio because of it's minimal demands on signal. Alas, in digital TV, it's all packets in the same stream and the decoder either can't or won't bother decodingh the audio if the video is lost. That's a real problem since is the video is disrupted, you can often follow a story OK, but when the dialog keeps going away you quickly get lost. Same problem if you're trying to get important weather information.
To top it off, as you say, they snuck the power down when the transition happened.
