A/C compressor (and fan motor) are drawing voltage down upon start faster than generator voltage regulator can respond.
Lower voltage=higher amp draw=shortened life span
Get a simple plug in voltmeter...plug it into an outlet where it can easily be seen and check the voltage when starting the A/C using generator.
Most 'power protection' (surge guards) devices trip on low voltage at 102V but that is just way too low for me.
I don't like running my A/C when voltage is below 108V AC for any length of time.
Plug in voltmeter.....
