I have a Auto whole home generator. It's a Briggs and Stratton 12kw. It will run our whole house with no problems. Installed in 2005. No problems with engine or generator. My problems have been with charging and battery and starter. Replaced starter and most of problems went away. But while I was at it added a Battery Minder, maintainer/charger. Removed battery from enclosure and put in it's own battery box. Use a full size 24 car battery. The battery that is inside enclosure needs to be a AGM so it does not rust out enclosure. They cost a lot more than a standard maintenance free car battery. We get temperatures well below 0°. So I have heaters for engine oil and battery.
My ATS is a Cutler Hammer 200 amp. Had only 2 problems with it. A wire came off a relay that made generator not do a 20 minute run each week. Created a fault light on monitor. Took longer to get cover off ATS than to find and repair the wire.
Another problem that I have had is one leg of the 220 was low voltage. But Generator needs both legs low to switch on. I now have a voltage monitor to check voltage on both legs of 220. Have a 200 amp disconnect/circuit breaker between meter and ATS so I can force ATS into running on Generator.
I would hope that they have ATS that will monitor both legs of the 220 and switch the ATS to generator. RV's can have this on 50 amp. Should not be a problem to have it on a whole house system.
When I bought mine the only whole house system available in my area was Generac and B&S. There a several other manufactures today.
My generator can run on either NG or Propane. I use NG because that's what I have. The generator only puts out 11kw on NG. But it's enough for my house. The only thing that will not run on it is full size range oven.
I am thinking of adding a battery maintainer on my Generac. What brand of maintainer did you buy?
