Why Are Inverter Generators So Quiet?

why are inverter generators so quiet

Inverter generators are quieter than their conventional counterparts. Manufacturers of inverter generators often add mufflers to their designs to minimize engine noise. According to the manufacturer, a muffler can reduce engine noise by 10 decibels. You’ll find less noise and more outlets with an inverter generator. But what makes them quieter than their conventional counterparts?

Less noise

One of the main benefits of inverter generators is that they are much quieter than conventional generators. Conventional generators essentially run a car engine with an alternator connected to it. The engine runs at a specific speed to generate the desired AC frequency. The alternator then slows down or throttles up to keep the engine speed constant. The output of the alternator is then directly connected to the load. Since the output of a conventional generator is not processed, the noise that you hear will be reduced. The power that you receive from this generator will be as clean and consistent as the power you would receive from an electric company.

Inverter generators produce less noise than conventional generators, due to their advanced noise-reducing technologies. They also use good mufflers and casings that absorb sound. Conventional generators are not nearly as quiet as inverter generators because of major differences in their working mechanisms. Conventional generators can be quieter if you install mufflers or use a sound-dampening system, but they can’t come close to inverter generators’ low noise level.


When choosing the right inverter generator for your home, make sure you look for one with a CO shut-off feature. This feature is vital for safety, as it prevents carbon monoxide (CO) poisoning. Many newer models are now equipped with a CO sensor, which triggers an automatic shut-off when dangerous levels are detected. In addition to being more environmentally friendly, inverter generators are also more fuel efficient, which means you can run them for longer periods without having to refuel.

Non-inverter generators create dirty power, which can cause harm to sensitive electronic equipment. This power has high levels of total harmonic distortion (THD), a measure of the variance of a standard 60-herz frequency. These fluctuations can cause your computer to lose memory or run into operating errors. Therefore, it is crucial to look for an inverter generator with low THD. If you have sensitive electronic devices or appliances, look for an inverter generator with a low THD rating.


If you’re considering an inverter generator for your camping trip, be sure to find one that is quieter than others. The Champion EU2000i Camo, for example, only produces 58 dBA at 23 feet. This means that you can have a conversation and not hear the noise from the generator. It also features low idle mode for improved fuel efficiency. You’ll also get alerts when the oil is low or the generator is overloading.

Inverter generators are usually cheaper, but their efficiency can be questioned if you use them constantly. They are quieter than their counterparts, and some models are even quieter than gasoline generators. A few features to look for in an inverter generator include fuel gauges, wattage indicators, and run time indicators. Some models don’t even have them. A fuel gauge is a bonus, though it’s not mandatory.

More outlets

Inverter generators are much quieter than their regular cousins. Subaru inverter generators can run at 58 or 62 decibels. By comparison, normal speech makes 60 decibels of noise, a vacuum cleaner makes 70 decibels, and standing on the curb of a busy street creates 80 decibels of noise. Heavy city traffic, on the other hand, can reach a hundred decibels.

Easy to maneuver

When you need a portable power source, you’ll want to choose an inverter generator that’s easy to maneuver. The EU7000iS is easy to transport, with a push button electric start, but recoil starting is also available. You’ll also appreciate the features of this unit, such as Oil Alert (r), which will protect you if you need to top up your oil. Additionally, this model is built with electronic circuit breakers, making it safer to operate even in adverse conditions.

Some inverter models are small enough to fit inside your suitcase and are even portable. Those with 2200-watt ratings are lightweight and convenient for outdoor events or primitive camping. Many of these models also feature USB ports for easy charging. They’re great for light construction projects and have convenient features such as ECO mode, which slows down the engine when there’s less load and speeds up when a load is added. Other features include an Idle control, which helps prevent wear and tear on the engine.
