I did a brief search and found a case of a line worker dying due to someone backfeeding a gas generators after a hurricane:(https://www.oshrc.gov/assets/1/6/06-0166.pdf https://www.oshrc.gov/assets/1/6/06-0166.pdf) Clearly this could happen with a dumb diy solar install, but also the case text shows that the company knew this was a possibility and enumerates several ways this accident could have been avoided.

I've seen that one before, and... as I mentioned, quite a few safety protocol violations in, bad things happened. They didn't force the line dead by grounding it on both ends, they didn't test to see if it was actually energized, and they didn't use the proper equipment or procedures to work on it as though it were energized. You can get away with that for a while, but at some point, that's going to bite you, and given power line voltages, bite hard. But I've yet to see "plenty" of deaths attributed to DIY solar. A downed grid segment looks like a dead short to an inverter, and anything even faintly UL listed (even with a "UL Listed" sharpie marking on the box) shouldn't be feeding into a totally dead grid segment at all. Most of the grid tie inverters lack the ability to create a waveform in the first place - they can only feed into an existing waveform.
