Can My Generator Harm My Inverter/Charger? Have You Heard of This Test with a Microwave?

Question:

I recently read about a test to determine if my generator and inverter/charger are in sync. You turn your generator on, then put your microwave on for 1 minute and the timer on your phone on for 1 minute. If they end at the same time then they are in sync. Have you heard of this? - Ross

Answer:

A properly working generator will have no problem working with the charger function of an inverter/charger. Practically all boats that have a generator also have an inverter/charger, both can co-exist without a problem. I have never heard/read about this test. - Jeff
