How many watts can a G320 supply @ 80vdc / 20 amps.

W=E x I

W=80vdc * 20A

1600watts

Is this correct?

Yes.

I believe something like IRF540 is used. So heatsinking/airflow may be required to deal with ~35W waste heat (20A² * 0.044ohm Rds * 2).

More like 80W when you add switching losses at 1600 Watts. That's a lot of heat to get rid of even though the drive is 95% efficient. A practical maximum is 1000 Watts. Don't overdo it; look at the size of the drive, look at the size of your motor. If it looks like a flea and an elephant in love, get some other company's bigger drive.:-)
