Long story short, I purchased a new home in the Bethesda MD area. The previous owners had a Westinghouse WH7000EC 7000 Watt generator that they never used and a hookup/transfer switch to the home electrical panels. I presume they did not know how to take care of the generator and they left it rotting in the back of a garage for the many years that they owned it. I looked though it and found out that the entire engine assembly was toasted. Now we want another generator so that we can actually use the transfer switch we poured money into to connect it to a new renovation. The house I have is around 3,800 Sq ft and the generator is used as a backup source for storms and the likes. We don't feel like paying thousands for a standby generator unit and just need a portable one that gets the job done, any recommendations?
Edit: The house electrical inlet uses 30A/250VAC and we can't use natural gas sources. I don't feel like routing gas into the generator area.
