No doubt, inverter generators are popular for their portability and fuel efficiency.
However, another aspect that distinguishes inverter generators from portable ones is their low noise operation.
Although both these generators are fitted with mechanical engines, why are inverter generators so quiet? To seek an answer to this question, just continue reading.
Reasons Why Inverter Generators are so Quiet
There are two basic technological differences between the portable and inverter generators, which relate to the difference between their noise level.
- Design changes
- Mechanical differences
The inverter generators have specific design features, which render them less noisy as compared to the conventional ones.
First of all, their body is designed in a compact way, and the engine is completely covered. This absorbs most of the noise, making the inverter generator less noisy.
In addition, the muffler attached to the engine reduces the noise even further. The material used for the manufacturing of this muffler is also specifically designed to lower the engine noise.
Apart from the mufflers, the overall casing of an inverter generator lowers the noise level. Furthermore, the material used for the housing also helps to absorb most of the vibration.
Besides all these features, inverter generators are also fitted with insulating materials. This helps to prevent the sound waves from expanding.

The mechanical technology used by an inverter generator to produce electricity is relatively different from that of a portable generator.
The engine of an inverter generator is small in size, which is one of the basic reasons for low noise operation.
In addition, the inverter generator creates electricity by following these steps.
- Conversion of high-frequency AC into DC
- DC is then inverted into AC
DC tends to travel in a flat line, which produces not much noise. Moreover, the sine wave of the AC produced by the inverter generator travels in a perfect wave, which also produces less noise.
These steps are followed to utilize most of the engine’s power. This is essential as the engine used in inverter generators are of small capacity.
The inverter generator can easily run at a constant speed of 3600 rpm. Moreover, it can also adjust the load to meet the needs of power.
On the other hand, the engines fitted within inverter generators are quieter than those used with conventional generators. In addition, these generators are relatively smaller in size.
Although the power output of these generators is small, it can produce sufficient power to meet the needs of an RV or that of a camping site.
As stated in the beginning, the most significant advantage of an inverter generator is their less noisy operation.
The manufacturer also tries to enhance the performance of these generators by introducing innovative technology.
The engine is smaller in size, yet it produces enough power to generate the desired amount of current.
To conclude, the most obvious reasons for the low noise of an inverter generator include smaller engine size, proper insulation, specially designed casing, and mufflers.
