kohler vs generac 20kw generator


As homeowners, we all know how important it is to have a reliable standby generator to keep our homes running smoothly in case of power outages. Two of the most popular brands in the market are Kohler and Generac, both known for their high-quality and dependable generators. In this review, we will compare these two brands and see which one comes out on top.

Comparative Analysis

When it comes to power output, Kohler and Generac are pretty comparable. Both offer generators with wattages ranging from 8,000 to 20,000, suitable for a wide range of home sizes.

In terms of engine performance, Kohler’s engines are known for their exceptional power and reliability. They use high-quality components and innovative technologies to ensure smooth operation and low fuel consumption. Generac, on the other hand, uses their patented OHVI engine, which is designed to run for longer periods without overheating or losing power.

When it comes to fuel source, Kohler generators can run on either natural gas or propane, while Generac generators are designed to run on natural gas or liquid propane. Both brands offer a runtime of around 10-12 hours on a full tank of gas.

In terms of accessories and features, Kohler and Generac are both fairly evenly matched. They both offer a range of features such as remote monitoring, mobile apps, and automatic transfer switches to make their generators user-friendly and convenient.

Design and Build Quality

When it comes to design and build quality, Kohler and Generac are both known for their high-quality products. Kohler generators are built with a durable, corrosion-resistant enclosure made of aluminum or steel. Their frames are designed to be extra sturdy to withstand harsh weather conditions. Generac generators are built with a similar design, but they also have a durable polymer enclosure that is corrosion-resistant and can withstand outdoor elements.

Both brands prioritize safety features. Kohler generators come equipped with QuietConnect™, which reduces noise emissions for comfortable operation. Meanwhile, the Generac TruePower™ technology ensures clean and reliable power, protecting your home’s sensitive electronics.

Noise and Ease of Installation

In terms of noise levels, both Kohler and Generac generators are designed to operate quietly. Kohler generators are built with sound attenuation technology and insulated enclosures, which help decrease noise levels. Meanwhile, Generac has a low-tone muffler and vibration isolation mounts that reduce the noise produced by the generator.

Both brands also prioritize ease of installation. Kohler generators are designed to be easy to install, with a compact design and easy-to-follow instructions. Generac generators, on the other hand, come with detailed videos and expert support to help ensure a smooth installation process.

Customer Support and Warranty

When it comes to customer support, both Kohler and Generac are known for their attentive and helpful service. Kohler offers a 5-year warranty for their generators, while Generac offers a 3-year warranty. Both brands also offer 24/7 customer support to ensure that any issues are addressed quickly and efficiently.


After comparing Kohler and Generac, we can see that both brands offer high-quality standby generators that are reliable and efficient. While there are some differences in engine performance and fuel source, both brands are fairly evenly matched in terms of features and accessories. When it comes to design and build quality, they both prioritize durability and safety features. Ultimately, the decision between Kohler and Generac will depend on individual needs and preferences. But no matter which brand you choose, you can rest easy knowing that you have a reliable standby generator to keep your home running smoothly in case of a power outage.
