An independent frequency generator is too much expensive.
Some of them have a tachometer to control rotation speed.

That's not how it works.
The generator supplies the raw energy to run an inverter.
Locking an inverter to a crystal is simple, and you get
and output frequency with 50 ppm accuracy.

Besides, what good does "phase locked to the mains" do when
it's obvious that you're running a generator because the
mains have gone down.
