22kw vs 24kw generac generator


Power outages can occur unexpectedly, and having a backup power source is crucial to ensure you don’t run out of electricity. Generators are the perfect solution to tackle power outages, and the Generac brand is one of the most popular brands in the market.

As someone who has had enough experience with power outages, I decided to compare the 22kw and 24kw Generac generators to help you make an informed decision before investing in one.


Features and Specifications

The 22kw and 24kw Generac generators share similar features and specifications. Both generators have a 999cc engine displacement, come with remote monitoring, and run on natural gas or liquid propane.

Power Output

While the 22kw and 24kw Generac generators have a similar power output, the 24kw generator can power more appliances than the 22kw. If you have a big family or use more appliances, the 24kw generator would be a more suitable option.

Cost Comparison

The 24kw Generac generator is priced slightly higher than the 22kw generator. If you have a limited budget, the 22kw generator would be a better option.

Fuel Consumption

The 24kw generator has a slightly higher fuel consumption rate than the 22kw generator. However, the difference is negligible and won’t significantly impact your overall fuel consumption costs.

Installation Requirements

The 24kw generator requires a larger gas line and concrete pad installation compared to the 22kw generator. So, if you have limited space or don’t want to spend a lot of money on installation, the 22kw generator would be a better fit.

Noise Levels

The 24kw generator has slightly higher decibel ratings compared to the 22kw generator. However, both generators emit similar noise levels and won’t cause any significant disturbance.

Maintenance Requirements

Both the 22kw and 24kw generators have regular maintenance requirements, but the 24kw generator requires more frequent oil changes. So, if you don’t want to spend a lot of time on maintenance, the 22kw generator is a better choice.


When it comes to choosing between the 22kw and 24kw Generac generators, it ultimately depends on your specific power needs and budget. Both generators are reliable and provide an excellent backup power source during power outages.

If you have a large family or use more appliances, the 24kw generator would be more suitable, but if you have a limited budget or space, the 22kw generator would be a better fit.

Overall, I recommend investing in a Generac generator to avoid the inconvenience that comes with power outages.
