Re: Back up generator - choosing and how to connect them?
If you are looking to power a portion of the house with the generator, then you must have a disconnect installed between the generator and the house main. The disconnect will protect the generator and the house when the municipal power comes back. If you simply run a few things off an extension cord, then no disconnect is needed, which will save you quite a bit of money.
As for generators, most of them, regardless of price, but particularly the cheaper models/brands, provide "dirty" power. Dirty power is full of spikes and drops in voltage, which will destroy anything electronic, and let's face it, few things made today aren't full of computer chips, whether it's a refrigerator, tv, microwave, or even a toaster or coffee pot. There might be a filter that will clean up the power supply, for that you'd have to talk to an electrician or someone who knows generators.
If you want a plug and play generator, look into the Honda EU series. These units are not only quiet, they produce clean power. They are a bit more expensive than a run of the mill generator, though, with the alternative of frying one of your beloved electronics, the safety of clean power will pay for itself.
