The panels themselves are DC, but there's an inverter feeding 120V 60Hz (or whatever) into the wall, right?

Yes, but it's a system that is designed to sync with the frequency of whatever other electricity is out there, and it shuts of if the main shuts off. Almost all rooftop systems without a battery in the US are set up the same way.

Still, it's important to check that things you think are disconnected do not have current flowing through them. And this makes it more important.

Pure sine wave or modified? Modified (square wave) are not good for electronics, particularly computers.

The answer likely varies by model. Check.
