Home standby NG Generac 6237 (6 months old) works fine but 3-4 times has operated without need (loss of power to house). Starts, runs, dies down after a few min, detecting all is well.
But latest incident was scary --- it tried for some time to electrify an electrified house, banging the solenoid in the transfer switch for many minutes as it cycled, until Generac over the phone told us to turn it off and get dealer to check.
Dealer of course wants to charge for service and initially thought it was due to installation, which I had done by my own (experienced) electrician. He has been here several times to check the house side, and Eversource has tightened the street connection. (Last incident followed that tightening.) Transfer switch remains okay but generator is now disconnected from the house circuit; wife was concerned.
Generac spoke of controller settings and firmware updates blah blah.
Dealer says voltage sensitivity is probably okay (~20% drop is threshold), though electrician says he has seen new generators be buggy out of the box many times. Electrician added that perhaps one leg sagged, or ground problem, unit settings yes, that sort of thing.
I say it is a 'fitness for use' issue and falls under manuf defect. I can see I am going to wind up paying dealer just to troubleshoot and get a diagnosis, hopefully honest. Dealer is smart and reputable, but.
Sorry to go on. Does anyone have any thoughts or experience about this sort of issue?
I see that other Generacs have a timer setting to prevent nuisance startups(!). Default = 5s, variable over a huge range. But Generac and dealer did not mention that. Or not yet.
Opinions?
PS -- oh yeah, dealer suggested asking Eversource to do a stress test (beast test, I think he said), pulling 200A yada yada. I have not called them for that yet, hoping someone here would have wise thoughts about nuisance startups in general and in particular.
