I was thinking of solar panels, but rotary devices (such as wind generators) are inherently AC. But then frequency regulation was the problem I had in mind when "paralleling" it to the grid. (Get it wrong, and the generator may be "motorized"!) But apparently, that's a 'trivial" problem.

I can grasp the idea of simulating a sinusoidal wave shape with tiny slices, but I thought that the tiny pulse "shoulders" would still create a problem. But I'm apparently wrong!

And thanks for realizing that it wasn't a "doofus" question!
