Comment:
We were very fortunate to have our 20kw Generac installed about 2 months before Hurricane Sandy. It ran for 11 days straight while our power was out, and needed one oil change during that period. Operationally it was excellent. We found that the total installation cost for this, and any permanent generator in our area, was very high because of required ConEd processes, slab to mount it, etc. The total cost to install was over $20,000. Also, our electrician is a Generac dealer and essentially refused to install at Kohler unit, a situation that we gather is common in our area.
How long have you owned it:
One-to-three months
Bottom Line
Yes, I would recommend this to a friend.

Comment:
Installed this a year ago at the cottage and it has worked great. Requires electrician to re-route existing power cables. I have tested it in -20 weather with no problems. You have to set up the weekly self test to get it to come on line which is not clear from the documentation. Small foot print and enclosure look great just like an air conditioner.
