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?
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. KB

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.
