Nevertheless, the CA Rule 21 requirement that homeowners have their systems shut off during grid downtimes seems nutty. As I understand it, those who install back-up generators have to install automatic cut-off switches to prevent power from going to the grid. Why can't the same be applied to panels?
Regular grid tied systems can't operate without power. And you cannot use a generator directly with grid tied solar, as it is possible to back feed the generator, if your usage is less than the solar produces.

Regular grid tied solar can modulate output like a DC coupled system.

I was reading through the SCE website and with the latest regulations, I seriously doubt they will allow a self done grid-tied install.
