Does anybody have a really good (cheap) source for permanently installed generators for homes?
What brand do you guys use?
Realistically what size is large enough to serve a house if they want to use A/C? I think a 15KV unit would be OK if they manage their power usage.
What happens if they try to draw more than the unit can produce? Brown out? Something trip?

guardian for residental is fairly low priced and not bad quality. being able to us ac will depend on what else is on the generatpr panel and is being used at the same time the ac is.

Generac & Caterpillar supplied generators for the last two highrise projects I was on

Onan runs ads for generators in the "Cottage" magazine I get.

I'm trying to figure out the generator thing too, have a customer asking about one.

Ran across a cut sheet from Kohler, says it can start and run a 4 Ton A/C. I wonder if you could put a soft start on an AC condensor?.....

Does anybody know what brands are the most reliable? Who do you order these from? I doubt my supply houses have accounts with these companies

We install a lot of gen-sets but most are in larger commercial applications. I have become a big fan of Caterpiller, excellent equipment, support from our local dealer. Just completed start up on a small, 30KW, Caterpiller last week. It was a sweet little unit and be great on a larger residence.

The units have overcurrent protection on them. a 15KW has a 70 Amp breaker on it. The Guardian brand can have a 12 circuit pre packaged transfer switch with it, or you can get a whole panel transfer, in 100 or 200 amp configurations. They have started making them with main breakers in them, and are service rated. So, it depends on connected load, what the customer wants to run with the generator, and what kind they want(Brand, liquid or air cooled). Big price difference between the to, also the 15KW turns at 1800 istead of 3600, so noise can be a factor to the customer. the guardian line is very user friendly, but have had so cold starting issues. Onan is also a good quality brand, but very pricey.

"Just completed start up on a small, 30KW, Caterpiller last week."

We have a bid due next Tuesday that includes a 350kw Cummins. If we get the job that will be the biggest unit I've installed.
