Not sure what the generator is but most have the ability to adjust the output voltage and frequency. If you have the option you could just crank the generator output voltage up enough to make the UPS happy. Note that is done by adjusting the excitation voltage, not the speed of the engine. Engine speed changes frequency. (All of this assumes a traditional generator, not a inverter style generator like the small Honda’s)
