Those are the two brands I had looked at online, but didn't have any basis to differentiate between them, or to evaluate the effectiveness of their load management technologies.
I am preparing to install an automatic-transfer natural gas generator for an 1800 sq ft two-story residence (with basement) that primarily needs to guarantee that the two 3/4 HP sump pumps can operate. However, I'm sizing to also power the well, Nat Gas furnace, refrigerator, central A/C, and assorted other loads.
Again, the main concern is preserving the property in the event of power failure, comfort comes second. If the load management technology is good enough, the "comfort loads" could be prioritized to run only when the sump pumps and heat have all the electricity they require.
Again, this is my first time installing an automatic switch with a stationary generator.
I'm less concerned with specific model as which vendor to go with... I'm looking for air-cooled not liquid, and of course reliability. Bouncing around the internet I can find opinions either way... When you and your brother debate the issue, what are the pros and cons of those two brands? What has you sold on Generac? What makes him like Kohler better?
