> If I were making something for this problem I would make an AC-DC-AC converter with a PLL to divide the 60Hz input frequency to 50Hz to control the inverter.

I'd put a $3 breakout board with any microcontroller and quartz... why would you want to sync to power network in the first place ?

Iirc, the power grid frequency is adjusted over the long term to give excellent long term stability. A crystal will drift.
