Rated 5 out of 5 by from working flwlessly My Generac has already proved itself valuable and reliable to me. I am in a very rural area and my power is a little flaky at times. It has already come on at least 5 times that I am aware of and it has been a much appreciated convenience. The longest outage was about 7 hours and there was no issues during that time.

Rated 4 out of 5 by from This unit does everything I hoped it would do This generator has come to the rescue several times already since installation. One time for almost 72 hours. The auto transfer switch is the best part of the system. No going outside looking for cables and filling the fuel tank in the middle of the night. The only suggestion I have to make this unit the perfect system is to upgrade the manual to be a bit more clear as to how to reset alarms and weekly test run cycles so that a regular mechanically inclined person can perform these things in an easier, more time efficient manner

Rated 5 out of 5 by from Solid and reliable I've had the opportunity to have whole house power backup twice during power losses since moving into my home 6 months ago. The Generac functioned perfectly. The scheduled weekly maintenance cycles occur without a flaw. I enjoy this product.

Rated 5 out of 5 by from Installed about 2 months ago.... .......and turned on once during hurricane Hermine. Fairly quiet, and test mode is hands-free. Excellent quality, and I'm glad to have purchased this unit, which is constantly on whole house standby. I believe I will purchase the optional Generac Mobile Link to remotely monitor, and control on my iPhone.

Rated 5 out of 5 by from High quality, durable, reliable unit still looks brand new. Unit was installed 5 months ago. Maintenance occurs weekly right on time and unit is quiet which is what attracted me to the liquid cooled engine. We have had only one power outage so far and it kicked right in and kept everything running without a hiccup. Exterior is high quality and engine is well protected. It looks brand new inside and out. My only regret is the optional wireless local monitor. It has to be so close to the unit that it is really not useful to me.
