Take a look at the diagram now...thanks for the input.

I updated the circuit for possible 220VAC adaptation. I just need to
build a 2nd unit to see if this works.

Any comments?

You definetely need a way to sync your output to the 60 cycle
powerline and kill output back into grid if the power fails instantly,
so a lineman cant get hurt.
grid tie should be a more complex device:(
Although I will print this and show the diagram to retired engineer
who designed power distribution transformers for many years

You reused.. C1-C2, F1-F4, Q1-Q4, D1-D4
Won't fly as input voltage is too low. 3-50vdc into 240vrms, (424
vac peak).
No circuit to prevent both rails from connecting to same leg
simultaneously.
Huge amounts of harmonic noise and current spikes..
Never get past FCC nor the UL. Will radiate RF noise like.
Hot DC+ leg. Safety hazard.
Electrolytic Cap's will blow. Internal resistance will cause them to
heat up and explode. They don't like wide voltage cycles.

Any suggestions on fixing it would be greatly appreciated.
