briggs and stratton 20kw generator vs generac


As someone living in an area prone to power outages, I understand the importance of having a reliable generator to keep my household running during emergencies. In my search for the best option, I’ve narrowed it down to two popular choices: The Briggs and Stratton 20KW and the Generac generators. Both products promise reliable and efficient power, but which one should you choose? Let’s dive in!

Power Output:

Both the Briggs and Stratton 20KW and the Generac generators are impressive when it comes to power output. The Briggs and Stratton model offers 20,000 starting watts and 18,000 running watts, whereas the Generac generator provides 22,000 starting watts and 16,000 running watts. In terms of household appliances, both generators can easily power air conditioners, heaters, refrigerators, and other essential electronics.

However, the Briggs and Stratton model has a slight edge when it comes to powering larger appliances like HVAC systems, pool pumps, and well pumps. This is due to the higher running watts and the 5-year warranty that covers the management module.

Fuel Efficiency:

When it comes to fuel efficiency, there’s a clear winner: the Briggs and Stratton 20KW. This model has a fuel consumption rate of 2.4 gallons per hour at 50% load and a large 200-gallon fuel tank. The Generac, on the other hand, has a fuel consumption rate of 3.4 gallons per hour at 50% load and a 200-gallon fuel tank. This means the Briggs and Stratton model can run for up to 84 hours without needing a fuel refill, while the Generac can run for up to 58 hours.

Noise Level:

Generators can be quite noisy, so it’s worth considering the noise level of each product. The Briggs and Stratton 20KW has a decibel rating of 71 at 23 feet away from the generator, whereas the Generac is slightly louder at 72 decibels. However, the Generac generator has a feature called Quiet-Test which reduces noise levels by 50%, making it a better option for those living in residential areas or close to neighbors.

Ease of Use:

Both the Briggs and Stratton 20KW and the Generac generators are relatively easy to use. The Briggs and Stratton model has an automatic transfer switch that kicks in within seconds of a power outage, providing a seamless transition to backup power. It also requires minimal maintenance, and its compact design allows for easy installation in small spaces.

The Generac generator also has an automatic transfer switch and is easy to install. However, it requires more regular maintenance than the Briggs and Stratton model, particularly after extended periods of use.


When it comes to reliability, the Briggs and Stratton 20KW excels due to two key features. Firstly, it has a sophisticated management module that will protect the generator from damage caused by power surges or outages. Secondly, the model comes with a 5-year warranty on parts, service, and travel.

The Generac generator is also reliable and durable, with a solid steel enclosure that can withstand harsh weather conditions. It also has a 3-year warranty, although this does not cover travel costs for repairs.


Both the Briggs and Stratton 20KW and the Generac generators are pricey investments. The cost of the generator itself is similar for both models, but the cost of installation can vary depending on the complexity of the job. Additional costs may also include permits, site preparation, and fuel line installation.


In conclusion, the decision between the Briggs and Stratton 20KW and Generac generators ultimately depends on your specific needs. If fuel efficiency, reliability, and ease of maintenance are your top priorities, then the Briggs and Stratton model is your best bet. If you require quieter operation and the ability to power larger appliances, then the Generac generator is a better option.

Overall, both generators offer reliable and efficient backup power, so it’s worth choosing the model that suits your needs and budget. Remember to factor in installation costs and any additional fees when making your final decision.

What is the difference between Briggs and Stratton 20kw generator and Generac?

Both generators have similar power capacity, but the Briggs and Stratton generator is less expensive and has a slightly quieter operation. Generac, on the other hand, has a more extensive network of service providers and offers broader compatibility with remote monitoring systems.

How do I determine which generator is suitable for my needs?

The first factor to consider is the power requirements of the devices you need to power during an outage. Once you have determined the power usage, you can compare it to the rated power output of the generators. Other considerations include your budget, noise level restrictions, and the availability of service providers in your area.

What is the fuel consumption of the Briggs and Stratton and Generac generator?

The fuel consumption will depend on the load and the type of fuel used. In general, the Briggs and Stratton generator has a slightly larger fuel tank, but the Generac generator usually has a better fuel efficiency rating, resulting in a longer run time.

Can both generators be used for residential and commercial purposes?

Yes, both generators are suitable for both residential and commercial applications. However, the usage will depend on the power requirements and the duration of the power outage. Commercial applications typically require larger generators that can handle more extended run times and provide more power.

What are some safety precautions to consider while operating either generators?

Always follow the manufacturer’s instructions when operating the generator, including providing adequate ventilation and using the correct fuel type. Never operate the generator indoors or in a partially enclosed space. Additionally, avoid overloading the generator and only use it to power devices that have been verified as compatible with the generator’s voltage and frequency output.
