Understandable, however I guess it comes down to the mindset of why should one own a generator. Of course there’s those that might live in the boonies that need one for every day living, but for the majority of purchases I would assume it’s to keep the lights on when you loose utility power. No one who owns a Generator “wants” to go on gen power. It’s expensive.
That being said I’ll agree that you wont miss the “excercise” of the generator, but when the power does eventually go out, it could save you hundreds and pay off the cost of the extra CT’s in just a couple days.
To me, at least, it appears that the OP is attempting to justify the cost of the Flex vs non and he’s leaning towards not monitoring the gen. I’m attempting to show the other side as to why you should and based on real world experience, why I monitor mine.
So in a nut shell I’m saying don’t focus on the 15 minutes a week, because true, who cares all that much. Focus on the money you’ll pour out in propane cost when it does come on and you actually need it.
