You shouldn't have to buy anything to fix this problem. You should be able to accomplish this by adjusting the governor / idle speed of the generator to the rpm that produces a stable 60 hz signal.
Turns out to be non-trivial. The generator is a Champion 7500 Watt Dual Fuel. Said adjustment is under a cover, somewhere. The technical bulletin for adjusting it tells what to do, but doesn't include where the adjustment is located. It says, "Note: The governor throttle adjustment screw can be identified with yellow marking paint and a spring around the screw threads to keep it from changing adjustment." That's helpful, but it doesn't say what cover I have to take of to find it. It also says, "Refer to CPETB2050012, voltage adjustment technical bulletin for proper adjustment procedure." I'm still digging to find that bulletin.
Ideally, you'd have a cheap multimeter to use to quickly and easily dial in the rpm but if not, you could just try playing around with it until the battery accepts the signal and starts charging.
The generator has an "Intelligauge" – Three mode digital meter for displaying running hours, voltage and hertz, so I should be able to watch it while I make the adjustment.
