All else snipped because what I have to say is important and relevent:
Generators are three things. Temporary, essential and obnoxious.
They are all designed to give temporary electrical to the medically
challenged, the insecure, and the uninformed. People who buy these are of
different ilks. They really NEED to keep something going, like AC for an
asthmatic, or they REALLY need to keep their AC running at 54 degrees
because they are used to that. The uninformed just get them in case.
Unless you get a serious generator, one that has a diesel motor, and a huge
generator, it is an exercise in intellectual masturbation.
Those with rural retreats and remote locations know this. If you are going
to run 24/7 you need to get good stuff. Anything but good stuff doesn't
last. And it goes out at the worst time.
But, who can afford a diesel engine and a high kw generator? Not everyone.
In comes the uninformed. They buy inferior HF and the ilk generators
thinking that the promises on the brochure are true. Ahhhhhhhh, but
reality has a way of keeping things straight.
Bottom line, if you need a generator, figure it temporary at best. It is
only going to function for a finite amount of time, and you are only going
to use it when the other power goes out. Figure they are all obnoxious,
even the best make lots of noise and put out a lot of fumes. And figure
that you will have to spend some $$$ to get one that will be reliable and
last. That excludes HF unless you want a really short lifespan.
Just MHO, YMMV.
