All you need to know about the 11-20kva generators


11-20kva generators are a popular option for a wide range of applications. They are capable of providing enough power to run a small business, a construction site, or even a home during a power outage. In this blog, we will explore the features and benefits of 11-20kva generators.

Power Output:

11-20kva generators are capable of producing between 11,000 and 20,000 watts of power. This is enough to power a variety of appliances and tools, including refrigerators, air conditioners, and power tools. The amount of power produced will depend on the specific generator model and its fuel source.

Fuel Types:

11-20kva generators are available in both diesel and gasoline models. Diesel generators tend to be more fuel-efficient and offer longer run times, making them ideal for applications where the generator will be running for extended periods of time. Gasoline generators, on the other hand, tend to be less expensive and easier to maintain.


Many 11-20kva generators are designed to be portable, making them a popular option for construction sites and other applications where mobility is important. Portable generators are typically mounted on wheels or come with a handle for easy transportation.

Noise Level:

The noise level of a generator is an important consideration, particularly if it will be used in residential areas or other locations where noise pollution is a concern. Many 11-20kva generators are designed to be relatively quiet, with noise levels ranging from 60 to 70 decibels.

Automatic Transfer Switches:

Some 11-20kva generators come equipped with an automatic transfer switch (ATS). This feature allows the generator to automatically switch on and off in the event of a power outage. This can be particularly useful for businesses and other applications where a power outage can cause significant financial loss.

Parallel Operation:

Parallel operation allows multiple generators to be connected and run in tandem, increasing the total power output. Some 11-20kva generators are designed to be used in parallel, allowing users to increase the power output as needed.


Regular maintenance is important to keep a generator running smoothly and ensure that it lasts for many years. Many 11-20kva generators come with features that make maintenance easier, such as oil level sensors and automatic shut-off systems in the event of low oil pressure.


11-20kva generators are available at a range of price points, with prices typically starting at around $2,500 and going up to $10,000 or more. The cost of the generator will depend on the specific model, its features, and the fuel type.


Many 11-20kva generators come with a warranty that covers parts and labor for a certain period of time. It’s important to carefully review the warranty before purchasing a generator to ensure that it meets your needs.

Overall, 11-20kva generators are a versatile and reliable option for a wide range of applications. They offer enough power to run many appliances and tools, and their portability and quiet operation make them ideal for use in a variety of settings. With proper maintenance and care, an 11-20kva generator can provide reliable power for many years. You can contact Bellwood Rewinds for more information.
