i install lots of whole house generators over the years...heck ive put in 14 in the past 3 months alone. My own house has a MANUAL transfer system cause i see no need for instant start up and transfer. if im not home, i dont want it running. Alot of the auto start systems are installed in older peoples houses where they dont want to bother starting up and transferring power. they just want it to handle it automatically.
personally, i dont want my system running while im away or asleep. they do suck some fuel to be sure. But i dont mind the sound (honestly a 22KW air cooled genarac is quieter than my riding mower by 1/2). And a running generator is a nicer sound to my ears than the alternative....a pitch black night with me living by flashlight.
Most, but not all air cooled units operate at 3600 RPM. my older (16 YO) Onan runs at 1,800 rpm. Generac now sells a 20 KW synergy air cooled that switches into 1800 rpm when the demand is light, or 3600 when demand is higher.
when i do change to a larger auto start generator, it will be a 20KW LIQUID COOLED 1,800 rpm generac quietsource system. Ive installed them in the past. nice system, and i like the reliability of a liquid cooled unit.
im thinking of doing it next year....but we will see. The only reason to do so is to include my now completed basement onto the generator backup system. Ill not use the auto start feature by simply leaving the switch in the off position. As i get older, i may see the need for auto start.
I happen to know a great installer.....i see him in the mirror every day:cool2:
