20,000-Watt Air Cooled Automatic Standby Generator with 200-Amp SE Rated Transfer Switch is rated 4.9 out of 5 by 94.
Rated 5 out of 5 by from Quiet, efficient, GREAT quality Somehow the plastic access door got broken off during installation (It may have been cracked or broken before, I am uncertain). When I called I discovered that Generac has service 24/7 AWESOME. In addition imagine my surprise when Generac said they will just send me a replacement, no question asked. AWESOME service. Nice way to start my relationship with Generac. THANK YOU

Rated 5 out of 5 by from Looks nice! This is the first time I have actually looked forward to yet another power outage! They are a dime a dozen here. We plan to turn on all the lights and blare music out of the doors and windows for the neighbors to "enjoy" next nighttime power failure we have!
Date published: 2017-08-28

Rated 5 out of 5 by from Good unit easy to install The unit is easy to install and works great. Remember you need to purchase a battery it is not included. For contractors such as myself it adds to the materials cost.
