Micro CoGen.

Sorry Wayne, I have no input on the devices you have.

So here's the funny or sad aspect of it. I rang up the home # of an engineer I know at Generac. I haven't talked to him for a couple years and I wanted to pick his brain for you.  Seems the guy got the typical Generac employee ax last year. He was a mechanical guy that was doing the sheet metal type packaging of the home backup sets and has no idea as to system controls etc.

Here's a different insight to Generac.

I live very near the Generac facilities and I'm not surprised at your lack of support or product knowledge.
Generac has been an employment 'revolving door' for the last 30 years. The customer service person you spoke to yesterday may not be there tomorrow. I know more than 10 former employees and of course they all have sour grapes as an attitude. Relatively low pay, work you to the bone then spit you out within 3-4 years. It doesn't matter if you're shop floor or the C level people I know.

Generac works to this simple business model. Hurricane season. Build stock and fill rented warehouse space by July, fill the supply channel then can half of the workforce in August. Oh the engineering horror stories I have heard referencing the pathetic junk they produce.

Just sayin.....
