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.

Mobile Link is the optional cellular remote monitoring system from Generac that allows you to check your generator’s status from anywhere in the world using your computer, tablet or smartphone.

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 5 out of 5 by from Wonderful product I think your service and help were wonderful . Only complaint I have is , If you think at age 83 I could add oil and do all the thing Jordan told me about , I doubt I would be able to do . I would need your service to do everything . thank you.

Rated 5 out of 5 by from Excellent design and very user friendly The generator is very quiet and efficient. Our installer was very professional and gave us a thorough tutorial on how to operate and maintain our generator. I especially like the app that gives up to the minute access to information about the operating status of our unit. We enjoy the security and peace of mind knowing future outages will not disrupt our lives. We highly recommend this product.

Rated 5 out of 5 by from Great generator - whole home We had a whole project management team receive, install, and start up the generator. As far as Generac is concerned, it took a while to get this generator shipped, and when shipped, they drop shipped on our driveway without placement (or forklift) to the desired location. Moreover, the communication and information sharing with Generac was to be desired as I had to constantly call Sam's for an update from Generac with lack of information as to when/how the generator would ultimately be shipped/dropped off -- 2 months after order, 1 month after desired shipping date -- and Generac could seriously improve it's communication efforts with customers and vendors alike. Moreover, the generator requires additional installation of wireless hookup for notifications to your phone. Would've been nice if for $13,000 that was already included as a smart device without the need to spend yet another $450 for the accessory and installation. Positive notes on the product -- much quieter than prior Generac generators. Able to turn on with lower pressure gas (awaiting Atmos to upgrade our neighborhood to higher pressure gas).

Rated 4 out of 5 by from Too early to tell but looks promising We installed the 38KW machine from the QS series of standby generators. The installation is about a week old at the time of this review and hence the 4-star qualified review. What we can say is that the local company (dealer and installer) we dealt with was excellent. From the time of first inquiry and quotation from the company, they consistently delivered on time and as promised. The quality of their work is superb. We have only had the generator running for about 5 minutes when the machine was started at completion of the installation. The test manually detached the power company service causing the generator to start and pick up the electrical load for the house. This the generator did with apparent ease. It started and came up to speed within a minute of so, picked up the house load and ran for another few minutes when the electrical power service to the house was manually switched back to the power company. The generator ran for another five minutes or so with no load in a cool-down mode and then shut down. The generator is surprisingly quiet when running under load. House guests were unaware that the generator had started and run. In the best of worlds we will never have an outage. We live in a cold winter location in a semi-rural setting with no alternative to electricity as a power source for the house. But we now have the comfort of knowing that if we do have an outage that the generator will provide for full coverage of our electrical needs.

Rated 5 out of 5 by from Generac 38kw I have a 6800 square foot home. 6 central a/c and heating units. Pool and spa. 2 refrigerators and 2 freezers. Has no problems running everything in home. Cannot hear unit run in home. Its sits on 7 foot stand over wooden fence. Everyone passing down street sees the Generac unit.

Rated 5 out of 5 by from Excellent performance Had it installed about a month before Hurricane Laura. We had 3 families living here for a little over a week until the electricity came back on. It worked flawlessly as expected. Thanks for helping my family keep the everyday things we take for granted.
