Premium whole-house backup power with patented G-Flex™ variable speed technology that matches engine speed to electrical demand.


Up to whole house protection with the 200-amp, NEMA 3R (aluminum outdoor enclosure) smart switch.

Unlike competitive units that run at a constant speed, patented G-Flex technology allows the Generac Synergy to run at lower speeds when household electrical demand is light. That means significantly quieter operation at normal capacity, less fuel consumption when you need less electricity, and cleaner power than competitive air-cooled home standby generators.

Generac generators and engines are engineered and built in the USA*.
*Assembled in the USA using domestic and foreign parts

5 Year Limited Warranty for automatic standby generators.

Generac's G-Force Engine is a purpose-built, pressure-lubricated engine capable of handling the rigors of generator use, resulting in power that’s more reliable and requires less routine maintenance than any competitive engine. Learn more about the G‑Force Engine »

Quiet-Test™ Self-Test Mode runs at a lower RPM for a five or twelve minute test, making generators significantly quieter than other brands while consuming less fuel.

24/7/365 Customer Support Team standing by all day, every day from our headquarters in Wisconsin to answer any questions you might have.

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

Rated 5 out of 5 by from Does exactly what I need it to do Not only does the Synergy 20kw run everything I need it to run, Its also more fuel efficient then the other generators I had looked at, and its quieter than the others. During the initial test when it was installed it only took 11 seconds to supply power to my house, Very happy with my purchase.

Rated 5 out of 5 by from Synergy This is a great generator,it determines the power needs and only uses that much gas power,saves gas and has smart modules to regulate performance. Highly recommend.

Rated 4 out of 5 by from Not part of promotions The unit is fine. It does what it's supposed too. However, if the promotion offered is your deciding factor for which brand to buy then this unit is not for you. Even though the promotion says "Buy a standby generator". They do not honor this claim for all models.

Rated 4 out of 5 by from Great Product but Promotion doesn't qualify Purchased the Synergy 20kw stand-alone automatic transfer unit which is their top of the line generator for Residential customers. Unit looks good, runs good, even if we haven't been able to use it during a power outage yet. One issue is with the Generac promotions. Generac is promoting a free portable Inverter generator with a stand-along unit purchase... which was a sell point to purchase their best unit. However this unit doesn't qualify for the promotion. It seems crazy that you buy/have installed the premium unit, but it doesn't qualify for the free inverter while other lower cost units do. After purchase, and after my promotional e-submission was rejected, I went into the fine print of the actual submission form and didn't see this model listed... but it wasn't clearly shown on the front of the web site that this unit doesn't qualify. Very dissapointed on the promotion, and I even got my neighbor to purchase same unit as well.

Rated 5 out of 5 by from Just installed last Thursday We have a lot of water under our home and a very large sump pump. We have a dual marine battery back up but didn’t feel that that was enough for a long-term outage. Several of our neighbors have Generac units. We decided to join the club. We feel a lot better knowing that we’re protected from any situation now.

Rated 3 out of 5 by from Unit was defective. The is 20KW unit came with a crimped wire on the board which charges the battery. Waiting for a replacement board. Mobile Link app is terrible, after creating an account it cannot retrieve data and therefore is useless.

Rated 5 out of 5 by from At this point the product has performed as expected. The Generac Model that I selected was the Synergy Model due to its ability to produce a very minimal Harmonic distortion level. This is important for running the many computers that I am presently utilizing.. I have only used the system in a simulation - however, I was happy to find that the computers did successfully operate on generator with no major complications. That was the "deal maker" for me. At this point the Generac unit is operating exactly how I had planned. on it working during my research. The certified Generac installer was also excellent and made the task trouble free. The total project was a worthy investment. I would definitely recommend this unit for anyone that is using a large number or electronic components. You will have minimal interference.
