kohler 20kw generator vs generac


As someone who frequently experiences power outages, I understand the importance of having a reliable power generator. They not only provide electricity during an emergency but can also be used for recreational activities in areas without access to electrical grids. In this review, I will be comparing two popular power generators; The Kohler 20kw generator and the Generac.

Why Compare Kohler 20kw Generator and Generac?

Before making a purchase, it is important to compare different options to ensure that you make an informed decision. Buying a power generator is no different. There are various brands and models available in the market that might confuse buyers. Therefore, in this review, I will be breaking down the Kohler 20kw generator and Generac by comparing their features, pros, cons, and costs.


Power Output and Efficiency

The Kohler 20kw generator has an output of 20,000 watts and uses a powerful 999 cc Kohler Command PRO engine. The Generac, on the other hand, has an output of 22,000 watts and uses a 999 cc Generac OHVI engine. Both generators deliver enough power to run essential appliances in your home during an outage. However, the Generac is more efficient due to its larger engine, which produces more power with less fuel consumption.

Fuel Consumption Rate and Runtime

When it comes to fuel consumption and runtime, the Kohler 20kw generator is more efficient than Generac. The Kohler uses 100 cubic feet of natural gas per hour and can run up to 143 hours on a 500-gallon propane tank. The Generac, on the other hand, uses 117 cubic feet of natural gas per hour and can run for up to 124 hours on a 500-gallon propane tank.

Noise Level

Both generators operate at a noise level of around 66 decibels. However, the Kohler 20kw generator has a built-in, sound-deadening enclosure that makes it quieter than the Generac.

Installation, Maintenance, and Repairs

The Kohler 20kw generator is relatively easy to install and maintain. It comes with a manual that provides easy-to-follow instructions. However, it’s recommended that you hire a professional to install the generator. The Generac, on the other hand, requires professional installation and maintenance.

When it comes to repairs, both generators have a two-year warranty. Kohler offers a 5-year warranty with their models.

Size and Weight

The Kohler 20kw generator is more compact and lighter than the Generac, making it easy to move around. It weighs around 500 pounds while the Generac weighs about 572 pounds.

Features and Additional Costs

Both generators have similar features such as automatic transfer switches, LCD display, and remote monitoring. However, the Kohler 20kw generator has additional features such as an industrial-grade engine that is designed for heavy-duty use. The Kohler generator is also compatible with a variety of fuel sources such as natural gas, propane, and diesel fuels.

Regarding costs, the Kohler 20kw generator is slightly more expensive than the Generac. However, the warranty and additional features justify the price difference.


After comparing the Kohler 20kw generator and Generac, I would recommend the Kohler generator due to its efficiency, durability, and added features. However, it’s important to note that both generators are reliable and can provide power during an outage. When making a purchase decision, it’s crucial to consider your budget, power needs, and installation/maintenance requirements.

I encourage readers to share their experiences and thoughts on the Kohler 20kw generator and Generac in the comments section.
