Will, I think what you're looking for is a line/power conditioner <https://en.wikipedia.org/wiki/Power_conditioner>. But, as has already been said/suggested, it might be cheaper just to buy a new inverter generator, and sell the old one.
Robert's option of feeding a battery through a converter/charger is a common practice. In this case, you'd operate the station from your battery bank, which in turn is charged by a generator and/or (increasingly) solar/wind.
