Can Be Installed Just 18" From a Structure
Capability to be installed 18 inches away from a structure, ideal for areas with tight lot lines.  Generac’s is the only manufacturer of standby generators to have 18” offset on most of its residential lineup.

Our RhinoCoat™ powder-coated finish helps make corrosion-resistant aluminum perfect for all weather conditions.

Quiet-Test™
All backup generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Protector Series home generator runs its self-test at a lower, quieter RPM, which can be programmed to run weekly, bi-weekly, or monthly.

Mobile Link™ Connectivity
Comes standard with all Protector Series generators. Mobile Link allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet or PC. Easily access information, such as the current operating status and the generator’s maintenance schedule. Connect your account to an authorized service dealer for fast, friendly and convenient assistance. With Mobile Link, your generator is taken care of before the next outage.

Additional Features
Improved stub ups and electrical connection access decrease installation costs. All connections are dual conductor rated, and the implementation of quick connects for the control wires, completely eliminates the need for crimping or lugging.
Improved customer connection access, which decreases installation costs.

Rated 4 out of 5 by from Too soon We have only had our generator for a couple of weeks, and there hasn't been a power outage. So it is too early to give much more of a review than to say that the unit appears to be very well built, and the installation was very professional.

Rated 5 out of 5 by from Great generator Happy we got our Generac 27K liquid cooled Generac installed to prevent Texas power outages like we experienced in Feb. Good generator and features.

Rated 5 out of 5 by from Trusted Brand We’re new to the generator world and we chose to install the trusted name in generators. Certainly happy to have our whole house system in case of an emergency. We live near the water so storms tend to create more damage.

Rated 5 out of 5 by from Future AP has to be updated. The installation went well, a few glitches cut night light wire shorted out causing damage which I had corrected and the cover in the driveway has a vent hole that’s to large high heals could cause a accident looking to happen. A rubber plug drill 2 holes in cover with 1/4 inch drill solves the problem. I’m waiting for Reliable to address the problem. Also must settle my credits . All in all everyone has been helpful and professional.

Rated 4 out of 5 by from great generator but switch subject to elements We had the generator for a few days and when it snowed, it stopped working because the switch is in the open and the snow caused the switch to turn off. There needs to be an enclosure around the switch to prevent this from happening. It's no fun to fight through the snow to turn on the switch. We have placed a cookie sheet (with a brick on top) on the top of the generator which hangs over enough to protect the switch somewhat.

Rated 5 out of 5 by from First Liquid cooled this is my third Generac in my lifetime and my second since I’ve lived in stormy, power-outage prone Florida. I bought a slightly larger capacity unit that I need to power my home but being liquid cooled makes it considerably quieter than the air cooled units I had in the past and given my close proximity to my neighbors I thought that was the respectful thing to do so it was a win/win. it’s got lots of features my previous units did not have including the ability to monitor it on my iPhone which is cool. I am hoping it was an expensive insurance policy but I will never need but it sure is comforting to know that my house will be lit up uncomfortable through any sort of extended power outage, whether it’s a few hours or a few days. I have no regret making this purchase and would recommend it to anybody looking to install some peace of mind if they live in an area prone to brown outs and blackouts
