Why Are Inverter Generators So Quiet?

why are inverter generators so quiet

You might be wondering why inverter generators are so quiet. They can be a real boon to your power needs, but what makes them so quiet? These generators are very quiet because they can automatically adjust engine speeds to match the load. The inverter technology also allows them to throttle down when the load is light, which saves fuel and minimizes noise pollution. You can learn more about these generators and their advantages in this article.

Low starting power

Inverter generators are not as quiet as conventional portables, but they are more expensive than regular models. They also require much more power to start, typically five to ten times more than their continuous power rating. Because they are more expensive, inverter generators are best suited for emergencies and light construction work. However, they must be operated outdoors. There are several things to consider before buying one. This article explores a few of the most popular types of inverter generators.

High peak power

Inverter generators are a popular choice for home and business owners. These devices are very efficient at supplying power when a load needs it. Unlike conventional generators, inverter generators produce a lower THD (total harmonic distortion), making them more suitable for sensitive electronics. This means less fuel is consumed when the lights are not on and more during the time when the appliances are running.

Adjustable engine speed

Inverter generators are incredibly quiet. Their inverter technology automatically adjusts the engine speed based on the amount of power they are supplying. As such, inverter generators are especially suitable for tailgating, outdoor recreation, and other outdoor activities. Because they are so quiet, inverter generators are ideal for use in these environments. They are extremely durable, lightweight, and easy to transport.

High-frequency AC power

The difference between inverter generators and traditional generators is the noise level. Traditional generators never change their engine speed, which results in a constant loudness. Inverter generators adjust the engine speed based on the power demand, making them more quiet at lower levels. They generally produce 50 to 60-decibel noise compared to the 85 to 100-decibel noise created by a conventional generator.


Compared to conventional generators, fuel-efficient inverter generators save a lot of money. Instead of running their full engine speed, the engines of inverters automatically adjust according to the needs of the load. In addition, inverters run much quieter than conventional generators, saving both the environment and your wallet. This makes them an excellent choice for RVs and other homes. Fuel-efficient inverter generators are great for emergency power and backup power.


Inverter generators are quite different from conventional open frame models. They are lighter, smaller, and more convenient to transport. While both types have their advantages and disadvantages, inverters are often more fuel efficient than conventional generators. They also are much quieter, compared to conventional open frame models. This may be important for those living next to noisy neighbors. If you are considering purchasing one for your home, it is a good idea to use a checklist before you buy.


The engines of portable inverter generators produce variable frequency alternating current. This means that their engine speed varies depending on the amount of power needed. The higher the engine speed, the higher the frequency, while the lower the engine speed, the lower the frequency. This AC/DC conversion process is controlled by a microprocessor, which lowers the engine speed to reduce noise and maintain the output voltage. In addition, this technology increases the longevity of the engine.
