The Quietest Inverter Generators 2021 – Reviews & Buyers’ Guide

If you’re shopping for a generator, you’ll find several different types to choose from. Conventional generators are used more than any other type, and they’ve been around for the longest period of time.

Most conventional generators are powered by propane, gasoline or diesel. A standard generator consists of a motor, and it uses various fuels to run an alternator and generate electricity.

To produce a specific amount of electricity, the motor runs at a steady speed. Inverter generators are popular products, and they’re some of the newest products in the industry.

With state-of-the-art magnets and advanced electronic circuitry, inverter generators convert AC current to DC voltage, and once the conversion has been made, they convert the DC voltage back to AC.

The major benefit that this type of generator has to offer is adjustable electrical current. If you want the best quiet inverter generators, then you must know what to look for.

What to Look For When Buying A Quiet Inverter Generator

Out of several different types of generators, the inverter category represents some of the quietest products available. Many of the companies that make inverter generators use a decibel meter to measure how much sound is produced by the products.

If a product doesn’t have a decibel rating, you can use the wattage rating to approximate the noise level. Products with a larger power output tend to be louder. Since you need a larger engine to get more power, the noise level must also increase.

Many of the best quiet inverter generators produce between 50 and 60 dB, and when compared with conventional alternatives, they’re significantly quieter. It’s not uncommon for manufacturers to list a dB range for their products, which represents the lowest and highest potential noise levels.

The lowest number represents the noise level when the generator is isn’t under load, and the highest number tells you how much noise to expect when the generator is under heavy load.

Most inverter generators are naturally quiet and produce the same amount of noise as a conversation. However, some products produce significantly more noise and should be avoided.


Portability and Size

Some of the best inverter generators have a small, lightweight design, similar in size to many space heaters  or air compressors and just like these products, they’re easy to transport or keep inside of a garage.

Since these products are frequently used away from home, it’s a good idea to look for a portable, lightweight design. You should have no trouble transporting the product in your RV, boat or car.

Most conventional generators are very bulky and don’t offer the same level of convenience that you’d get from an inverter style.

 

Run Time and Fuel Efficiency

You can think of inverter generators as small engines, and like your car, they derive electrical power from a fuel source. When shopping for a quiet inverter generator, you need to consider the run time, which is determined by the size of the fuel tank.

In most cases, you can attach an external fuel tank to the generator and increase the total available run time. When compared with conventional alternatives, inverter generators tend to deliver better fuel efficiency and use engines that can adjust speed.

 

Noise Levels

One of the fastest ways to separate the different types of generators is to examine the noise ratings. Inverter models are designed to be much quieter than their conventional counterparts.

Inverter models are known to have special mufflers, quieter engines and special technology, which dramatically reduce noise output.

Conventional models are designed to run at a steady speed, and inverter models use microprocessors to adjust the speed of the motor. The major advantage of an inverter generator is its ability to adjust the engine speed based on electrical loads.

Most conventional generators run at a constant speed and can sound as loud as a chainsaw. Even if the load is reduced, the conventional model will continue producing an unbearable amount of noise.

 

Max Power Output

Before you decide on a particular product, you should consider its total power output. The total power output that you can get from a conventional generator might be between 500 to 50,000 watts.

Inverter generators are different because they’re smaller and designed for convenience. Most inverter models can produce between 1,000 to 4,000 watts.
