I am guessing the Generac generator controls deliberately drop the frequency rather than depending on the prime mover slowing down under load?The Generac Smart Modules detect the frequency of the power coming in. When it drops below the acceptable parameter (can't remember what it is right now), the module opens and removes the load from the generator. They can also lock out larger loads while the generator is running.
