5 Best quiet generators

• We named the Honda EU2200i the best overall quiet generator.

• Quiet generators are generally rated under 60 dB (A), roughly the same noise level as a typical conversation.

• Battery-powered generators run much more quietly than combustion-powered generators, though they’re often more expensive on a per-watt basis.

Generator noise can be a real annoyance for homeowners and their neighbors, especially after several days or more of constant use during an extended power outage. However, modern generators can provide backup energy without creating so much noise.

In this guide, we share our list of the five best quiet generator options. We go over the most important details of each model on our list and provide a quick lesson on how quiet generators work. You’ll also find a guide to costs and what to look for in a new whole-home generator or portable generator that won’t disturb the peace while it’s running.

The EU3000iS features electric start, Eco-Throttle mode for fuel efficiency, and a reputation for Honda-level durability. It’s ideal for home backup, tailgating, and RV applications.

How quiet generators work and why noise levels matter

With the introduction of quiet generators, manufacturers have addressed one of the biggest downsides of generators — the substantial noise they create while running. These newer generators have given homeowners a backup energy option that’s far less disruptive to their home environment and those around them.

What do decibel ratings mean?

Manufacturers typically list the noise rating of their generators in decibels (dB), often as a range or a maximum. Decibels are a scientific unit for measuring the volume of a sound, with higher numbers meaning higher volume. As a point of reference, normal human conversation is said to be around 60 dB.

Decibels measure sound pressure on a logarithmic scale. Every 10 dB increase sounds roughly twice as loud to the human ear. Normal conversation is about 60 dB, so lowering even 3 to 5 dB makes a noticeable difference.

How loud are generators?

Traditional gasoline-powered generators can be extremely loud. While standard generators tend to put out between 70-90 dB while in operation, some have noise levels that go as high as 100 dB, as much as a concert or chainsaw. 

Quiet generators running on fossil fuels typically produce less than 60 dB of operating noise, with many running at between 50 and 55 dB. Battery-powered generators (solar generators) often run at half the decibel level, making them quieter than a friend whispering to you a few feet away.

In the table below, we’ve listed the average decibel ratings of different types of generators and their real-world noise equivalents.

How do manufacturers make generators quieter?

Quiet generators are the result of multiple technological innovations. There are several ways that manufacturers have been able to reduce the noise their generators produce.

Inverter generators vs. conventional generators

Traditional, or conventional, generators create AC power at a constant rate. This requires the combustion engine to run at a consistently high RPM, which produces a consistently high level of noise. 

Inverter generators, on the other hand, use processors to convert AC power into more stable DC power, which can then be converted back to AC power if needed. As a result, the onboard motor can run at variable speeds, and most of the time at a low RPM.

This means inverter generators produce far less than their maximum noise level most of the time they’re in operation. Consider the difference in noise between revving the engine in your car and cruising at a low speed to get a sense for how this works.

Advanced soundproofing

Another way manufacturers have been able to reduce generator noise is by adding shielding that suppresses sound to their units. Similar to how soundproofing for music recording works, a layer of thick material, like metal or wood, lined with sound-absorbing materials like foam can significantly limit the amount of sound that escapes into the surrounding environment.

What about solar generators?

Solar generators don’t actually generate power the way fuel-burning generators do. They’re large rechargeable battery packs that store electricity from a wall outlet or solar panels. These systems use an inverter to convert stored DC energy into usable AC power for appliances. 

Because there’s no engine, exhaust, or moving parts, they operate almost silently and require little to no maintenance. Their main limitations are capacity and recharge time, which depend on battery size and sunlight availability rather than fuel supply. Keep in mind that a grid-tied solar array won’t provide power during an outage; you need a battery pack to store and use power.

Key features to look for in a quiet generator

A generator is a major purchase, so it’s important to weigh your options carefully. The most important features to consider when shopping for a quiet generator include:

• Noise level: Generators with operating noise levels of under 60 dB at 25% capacity are considered “quiet generators” and won’t disturb your environment.

• Fuel type: Most generators run on gasoline, but you can also find diesel and propane-powered quiet generators, as well as “dual-fuel” generators that run on both gas and propane. Gasoline is common, while propane burns cleaner and stores longer.

• Runtime: The listed runtime of a generator is the maximum amount of time it can run on one tank of fuel or a full charge. Quiet generators can have runtimes of up to 20 hours.

• Eco mode: Inverter generators often have an “eco mode” setting that runs the motor at a low RPM when energy demand is low. This conserves fuel and further reduces operating noise.

• Portability: Many generators have wheels and/or handles that make them easy to carry from one place to another. Consider whether you are likely to move your generator around a lot or if it is likely to stay in one place.

• Parallel capability: Some generators allow for parallel connectivity, which means linking two or more generators together to provide more power. This allows owners to scale their generator power without having to replace the current unit.

• CO monitoring: Combustion-powered generators create carbon monoxide as a byproduct, which is toxic or even fatal to humans. Many generators now feature onboard CO monitors to alert you if they are releasing dangerous levels of the gas.

• Connectivity: Some generators have built-in Bluetooth or WiFi capability that allows users to control, monitor, and manage them remotely through an app or website. 

Quiet generator costs and value considerations

Quiet generators typically cost between $800 and upwards of $4,000. In general, the price of a generator goes up as capacity increases. Combustion-powered generators are usually cheaper than battery power banks. Among combustion-powered generators, inverter generators tend to be more expensive than conventional generators.

Beyond price, fuel source, noise level, and capacity, there are a few other factors to consider when shopping for a generator. These include:

• Fuel efficiency: Just like with gas mileage in cars, some generators are more fuel-efficient than others. Even a slight difference in efficiency can add up to a huge difference in the cost of fuel over time.

• Maintenance needs: The amount of generator maintenance and upkeep needed varies between makes and models, as does the cost of replacement parts like air filters. Battery-powered generators require significantly less maintenance than combustion-engine generators.

• Brand reliability: Some generator manufacturers have a well-established reputation for making high-quality products that last. While generators from these companies may be more expensive than less-established brands, they often last longer and are more reliable.

• Size: Keep in mind that you will need space to run and store your generator. Since sizes vary, make sure you get a model that fits where you need it to.

Summary: Best quiet generators

We chose the Honda EU2200i as the best overall quiet generator, but that doesn’t necessarily mean it’s the right choice for you. Depending on your preferences for things like fuel sources, your energy needs, and your budget, another option from this list may be your best option. 

You should take the time to document your needs and wants in a quiet generator and then compare your options. This will ensure that you get the best possible value for your investment and a reliable source of backup energy for years to come.
