You probably have too much initial load on the generator before you turn on the A/C. Start the generator and go to the power panel (the one with all the circuit breakers). Turn off all the circuit breakers except for the main (probably a 30 amp) and the 20 amp A/C circuit breaker. Now see if the generator will accept the load - it should. Use this sequence - with only the two circuit breakers on - Turn the A/C on to "high fan" and let it run for about 10 seconds and then quickly rotate the switch to "low cool". An A/C needs about 40 amps for 1/4 of a second to start and then will settle down to about 15 amps steady. After the A/C has run for 5 minutes, you can switch to high cool if you desire. Now you can go back to the power panel and turn on the converter/charger circuit breaker but nothing else. You generator will only run the A/C with only one other device and maybe a TV, no microwave, no water heater. If you load it too much when the A/C compressor cycles it will stall the generator. You can buy a voltage/frequency monitor (about $50) to keep a eye on the generator. It just plugs into any 120 volt duplex receptacle.
