cummins home standby generator vs generac


Hey there, fellow homeowners! Today I want to talk about an important investment any homeowner should consider when experiencing power outages – a standby generator. In this review, I will compare two widely respected brands – Cummins and Generac.

Cummins and Generac are two of the industry’s most reputable brands when it comes to standby generators. The purpose of this review is to help you decide which brand is better for your needs. Whether you’re looking for a generator with exceptional performance, ease of use, or low maintenance, there are pros and cons of each model.

Design and Features

The design and exterior appearance of a standby generator is an important factor when choosing which one to buy. Cummins and Generac both provide excellent designs, but their appearance differs slightly. Cummins generators are sleek, compact, and have a modern appearance. Generac generators, on the other hand, are bulkier but have a traditional appliance-like appearance.

Both generators have a lot of features, such as remote monitoring, scheduling options, and internet connectivity. However, the Generac generator has more advanced features like a mobile application that allows you to control the generator from your phone.

When it comes to functionality and ease of use, the Cummins model is easier to install, and it has a more intuitive control panel. However, the Generac model has a higher amount of technical features which, although more complicated to control, provide greater functions to users.


The similarities and differences between Cummins and Generac generators are easy to spot when it comes to power output and capability. Cummins provides a standard range of power ranging from 13kW up to 20 kW. In contrast, Generac offers more power outputs ranging from 9kw to over 48kw for the largest generator in their line. Thus, if you’re looking for a generator that can handle a large or high demand, Generac is generally the way to go. Additionally, users of Cummins generators have found the generator to be quieter than the Generac, making it more desirable for those of us who enjoy a bit of peace and quiet in the midst of a power outage.

Furthermore, while both generators are efficient in operation, the Generac generator has a higher level of fuel economy due to its advanced features that help it conserve energy.

However, when it comes to determining which generator offers the best value for money, Cummins takes the cake. The Cummins model provides excellent functionality and power output, while remaining quiet and efficient, trading off a few additional functions in favor of a lower price tag.

Maintenance and Warranty

The maintenance of standby generators can be quite daunting, but Cummins and Generac have done well in terms of making the maintenance of their generators as simple as possible. Both models require periodic maintenance such as changing the oil filter and spark plugs. However, the Generac model requires more frequent maintenance than the Cummins one, highlighting the difference in technical intricacy.

Cummins offers a 4-year limited warranty for their standby generators as opposed to the Generac standard 3-year warranty. In addition, Cummins offers an optional 5-year warranty extension, which provides greater protection if any unforeseen circumstances arise during ownership.

In terms of reliability and value, the Cummins model stands out not only because of its lower maintenance frequency, but also because it offers more generous warranty terms to ensure maximum peace of mind.

Customer Reviews

Lastly, customer satisfaction is one of the most significant metrics when determining the value and performance of a product, and it is no different for standby generators.

After analyzing various reviews, it is clear that Cummins and Generac generators are both very well received by customers. Cummins generators tend to have higher consumer satisfaction ratings due to their simplicity and ease of use. In contrast, Generac generators tend to have more reviews on aggregate, which may contribute to the perception of a higher degree of confidence in the brand.


Both Cummins and Generac generators have a lot of great features and benefits, but the decision ultimately comes to your needs and preferences.

In conclusion, Cummins is the more reliable and satisfied product for homeowners who are after excellent performance and durability while providing ease of use and a better value for the money.

When considering purchasing a standby generator, be sure to weigh the factors and determine what’s most important to you. Hopefully, this review helps you in making an informed decision that suits the needs of your household.
