Quietest Generators For Home Use

Posted on  by admin

Let’s face it: Power generators can be very loud. Even when operating at 25% load, bigger 10,000W+ generators can produce more than 75 dB of noise (measured at 23 ft distance). Today, we will look at generators that produce the least amount of noise, and check out the 5 quietest generators currently on the market. Why would you want a super quiet generator? Well, nobody likes loud generators.

A quiet home generator won’t disturb your sleep or your neighbors. A quiet generator for camping or RV is preferred to loud units. Generally, generators that produce more than 80 dB of noise are considered to be ‘loud’. Generators that produce less than 60 dB noise levels are considered to be ‘quiet generators’.

Standards of the Best Quiet Generators

On top of that, you have to be aware of decibel restrictions for noise generation. Some cities and homeowner’s associations (HOA) have a policy that you should keep your home generator below 75 decibels. Anything above that can result in a fine, especially if you’re running a generator for prolonged periods of time. A general rule for camping sites is that a generator should not produce noise levels in access of 65 dB.

The best generators for camping and the quiet ones. How can we figure out which generators are the quietest? That’s pretty easy in theory. Check 100 of the best selling-generators, crack open the specification sheets, and write down the noise levels (measured in dB) of all the generators. You can easily figure out which generators produce the least amount of noise.

That’s exactly what we did to create a list of the 5 most quiet generators currently on the market (in the 50 dB range).

Example: A small 2,500W generator will always be quieter than a big 10,000W generator. That’s why we introduced a special parameter – Watts Per dB – to find the best compromise between the generator’s noise levels and power output. Furthermore, you have to check for the starting wattages, running wattages, tank capacity, and max. running time of a quiet generator.

Of course, you also have to take the price of a quiet generator, the brand of a generator, and user reviews into the equation. In the list of the whisper-quiet generators below, you will see a comparison of all these specifications for silent generators. To figure out what you’re actually comparing, we will go through these key parameters. First of all, however, it’s important for everybody who is looking to buy a quiet generator, to understand how we measure which generators are quiet and which ones are loud.

Here’s how we do that:. Before we check how loud 50-95 dB generators are, we need to look at how we test the generator’s noise levels.

1. Honda EU3000iS: Is This the Best Quiet Generator?
  • There’s a significant detail that refers to all, even the extremely quiet, generators.
  • If you crack open the specs sheet of any generator, you will see something like this:.
  • Noise levels: 68-74 dB.
  • The first-decibel level (lower sound limit) refers to the amount of noise a generator makes when operating at 1/4 (25%) load.
  • In this case, a 3,000W generator would be producing 750W of power.

5 Best Quiet Generators (Comparison Table + Reviews)

A big 10,000W would be producing a 2,500W load. Usually, you operate a generator at above 1/4 load. The second-decibel level (higher sound limit) refers to the amount of noise the generator is making when operating at full load (100% output). For example, that’s when a 2,500W is actually generating a full 2,500W of power output. Here’s the significant detail you need to be aware of:.

We measure the noise levels of generators from 23 feet away. A generator with 74 dB maximum noise level output will produce 74 dB only when it’s 23 feet (or 7 meters) away. If you stand right next to a 74 dB generator, your ears will likely suffer from 80+ dB noise. Because human ears can tolerate noise levels above 85 dB for only so long, the very idea of the quiet below 60 dB generator is so appealing.

To illustrate how loud generators actually are, let’s look at some decibel equivalent:. We use decibels (dB) to measure how loud or quiet generators are.

  • Here’s a bit complex definition of decibels from Wikipedia: ‘Decibel is a relative unit of measurement equal to one-tenth of a bel (B).
  • It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale.
  • Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately 1.26) or a root-power ratio of 101⁄20 (approximately 1.12).’.
  • To simplify that, let’s look at some real-life examples.
  • We can barely hear 0 dB.

Bottom Line

10 dB is the noise breathing makes. Whispering is at about 30 dB and refrigerators mostly run at 50 noise levels. Here’s a nice representation of different dB sounds:. As you can see, quiet generators are on the same sound levels as the fridge (50 dB) or a conversation (60 dB). Louder generators can produce as much noise as a truck (80 dB) or even more than a hairdryer (90 dB). When trying to figure out, for example, how loud is a 74 dB generator, you can check this illustration.

A 74 dB generator is as loud as a car or a bus (somewhere in between). Here are the sound ranges and consequently categorization of generators based on the amount of noise they generate:. Quietest Generator: Below 50 dB. Quiet Generators: 50-60 dB. Quieter-Than-Average Generators: 60-70 dB. Average Noise Generators: 70-80 dB.

Louder-Than-Average Generators: 80-90 dB. Loud Generators: Above 90 dB. Now, everybody wants the quietest possible generator.

Starting And Running Wattage (+ Watts Per Decibel Rating)
  • However, we do need to think about generator wattage as well:.
  • In the event of a power outage or for camping, you will need an adequately sized generator.
  • For power outages, whole-house generators with 10,000W+ running wattages are used.
  • For camping and RVs, you need about 2,000-3,000W running wattage quiet generators.
  • Obviously, the small generators for camping will be quieter than the big whole-house generator for power outages.

However, they are capable of generating 3-10x less power output. The key question here is this:. How do we account for different power generation when comparing which generators are the quietest? Example: #1 Honda EU3000IS generates 2,800W running wattage and has a 25% load noise levels of 49 dB (Honda generator is an incredibly amazingly quiet generator).

#3 DuroMax XP13000EH generates 10,500W running wattages and has a 25% load noise levels of 74 dB. Which one is quieter? Obviously, the #1 Honda EU3000IS is the quieter generator(49 dB vs 74 dB). That’s not surprising; Honda is a brand that produces the quietest generators and the EU3000IS model is the quietest of them all. However, we need to take power generation into the account as well.

#3 DuroMax XP13000EH generates 10,500W vs 2,800W running watts that the whisper-quiet Honda generates. Big generators produce more noise than small generators; how to put the sound-power compromise on the same common denominator?

Sources
  • The best sound-power compromise rating is the ‘Watts Per dB’ ratio.
  • This ratio simply tells you how many running watts does a generator produce per 1 dB.
  • Here is how it’s calculated:.
  • Watts Per dB Ratio = Running Wattage (W) ÷ Noise Levels (dB).
  • In our example, #1 Honda EU3000IS has 2,800W running wattage and 49 dB noise levels; hence it has ‘Watts Per dB’ ratio of 58W per dB.

Best Quiet Generators—Buying Guide

#3 DuroMax XP13000EH has 10,500W running wattage and 74 dB noise levels; hence it has ‘Watts Per dB’ ratio of 135W per dB. That means that #3 DuroMax XP13000EH will generate 135W starting wattage per every 1 dB. That means it has a ‘Watts Per dB’ ratio higher than even the #1 quietest generator Honda EU3000IS (58W per dB). We can conclude from this that, despite generating 74 dB noise levels at 25% load, the #3 DuroMax XP13000EH is actually quite a quiet generator given its whole-house generator size.

If a big 10,000W generator would have a ‘Watts Per dB’ ratio of less than 50, it would be a big red flag for picking quiet generators. We would immediately know that’s a very loud generator. The best quiet generator should primarily be as quiet as a mouse. On top of that, it would also be a great generator. Having a big enough gasoline or propane tank capacity to run a generator for at least 10 hours is an integral part of the better generators.

Depending on the generator capacity, these units will have anywhere from 1 to 10-gallon fuel tanks. Generators run either on gasoline or propane, or both (quiet dual fuel generators).

Other Generators Articles
  • According to Engineering Toolbox, here are the energy density of gasoline and liquid propane (LPG):.
  • 1 gallon of gasoline contains 124.000 BTU of energy.
  • That means that 1 gallon of gasoline can generate 36.34 kWh of electricity.
  • At 100% generator efficiency, you can run a 3,000W running watts generator for more than 12 hours.
  • 1 gallon of liquid propane (LPG or liquid petroleum gas) contains 91.330 BTU of energy.

Things You Should Consider in Buying Quietest Generator

That means that 1 gallon of liquid petroleum can generate 26.77 kWh of electricity. At 100% generator efficiency, you can run a 3,000W running watts generator for almost 9 hours. In general, gasoline generators will have a 36% longer running time because the energy density of gasoline is 36% higher than liquid propane energy density. The most energy-efficient quiet generators are the inverter gasoline generators.

Example: #1 Honda EU3000IS is the quietest inverter generator on the market. It has a 3.4-gallon gas tank and it can run on 2,800W for 20 hours. Note: The added bonus of an inverter generator is that it can run at extremely low noise levels for a generator. Honda’s 3.4-gallon tank can hold 421.600 BTU worth of gasoline. At 100% energy efficiency, this would generate 123.56 kWh of electricity.

Here’s why quiet inverter generators are preferred:. The standard generator runs at the set output (usually 100% load) all the time.

Other Best Product Articles
  • That means that even when you don’t need 5,000W for example, the standard generator will burn through gas supplying 5,000W whether you need it or not.
  • It will generate a lot of noise all the time.
  • On the other hand, the inverter generator adjusts its power output to the electric demand.
  • That means it can reduce power output (and handly minimize noise levels) when the electric demand is decreased.
  • This makes inverter generators much more energy-efficient and quiet compared to standard generators.

There is no quiet whole-house generator. The best you can do is to get the quietest possible home generator and with 74 dB noise levels, that’s the DuroMax XP13000EH. If you look at the watts per dB ratio, the DuroMax XP13000EH is actually one of the most silent big generators. It has a running wattage of 10,500W (enough for a whole house) and a 135W per dB ratio.

That’s very high, even for a big generator. Fuel-wise, the DuroMax XP13000EH is a dual fuel generator. You can fill it up with either gasoline or liquid propane (gasoline is preferable due to higher energy content per gallon). It has a big 8.3-gallon tank which can, when filled with gasoline, last for up to 16 hours. All in all, if you need a big quiet dual fuel generator for your home, the DuroMax XP13000EH is a reasonable choice.

8. Best Quietest Propane Generator—DuroMax Generator

Yes, it has 74 dB noise levels, but all other 10,000W+ generators have even higher (some more than 85 dB) noise levels. With a $1,500 price tag, it’s a budget-friendly generator considering its big 13,000W starting wattage capacity:. Here’s the deal about quiet generators for camping. It’s not enough they are whisper silent.

They need to be big enough to power all your electric devices when camping (more than 1,000W running wattage) and light enough so that you can carry them (below 50 lbs). The best quiet camping generator that hits all the marks is the WEN 56203i. This is a 2,000W starting wattage and 1,700W running wattage portable generator. At quarter load, it generates only 51 dB.

That’s quiet enough for camping sites (needs to be below 65 dB) and even quiet enough for you to sleep near it. The key to the low noise levels is the inverter 4-stroke 79cc OHV motor. Together with the eco-mode feature, this inverter camping generator will be as quiet as possible and as energy-efficient as possible.

The power output (and correspondingly the decibel production) adjusts to the power demand. That means that if you’re camping and want to just fill your mobile phone, the WEN 56203i won’t operate at full load. The load will be reduced even below 20% and hence the noise levels will drop significantly. An important specification for a quiet portable generator for camping is the weight.

7. Best Lightweight Quiet Portable Gas Generator—Champion Quiet Generator

Anything that’s above 50 lbs it’s almost impossible to carry around the camping site (and most generators are much heavier than 50 lbs). WEN 56203i has a weight of only 39 lbs and is quite portable (you will still need stong hands). A full 1.0-gallon gasoline tank will run it for up to 10.8 hours. With a price tag of below $500, the WEN 56203i is overall the best quiet portable inverter generator for camping sites:.

Champion 200951 is another lightweight 39 lbs whisper quiet portable generator for camping. It’s a bit bigger and hence a bit louder than the #4 WEN unit, and it costs a bit more. However, it does provide a bit more power and can use both gasoline and liquid propane to provide electricity while camping. This is a 2,500W starting wattage and 1,850W running wattage portable generator.

At 25% load, the Champion 200951 produces all-in-all 53 dB of noise. It has a 1.1-gallon tank. Remember, this is a quiet portable dual fuel generator; you can fill it up with either gasoline or liquid propane. If you use the energy-richer gasoline, the Champion 200951 can run for up to 11.5 hours. Needless to say, this is an inverter generator; hence the much lower-than-average noise levels.

Champion 200951 is usually available for less than $700:. This has been an analysis of noise levels in power generators. If you have any questions regarding the decibel levels, how generator noise levels are measured, and so on, you can pose the question below and we’ll try our best to help you out.

9. Best Smallest Quietest Generator—SereneLife Portable Generator

Welcome to the Thomas guide to the best quietest portable generator in 2022. Thomas has been connecting North American industrial buyers and suppliers for more than 120 years. When you purchase products through our independent recommendations, we may earn an affiliate commission.

With power shortages occurring in the USA more often than they used to (much more than any other developed country thanks to outdated grids, and lack of maintenance and upgrades), many are seeking out the quietest portable generators now more than ever. You'll likely already be aware of the usefulness of portable generators, and maybe even have yourself one or two, but after realizing the racket conventional portable generators are known to make, you can be forgiven for wanting to upgrade to a quieter model.

We scoured the market and found some of the quietest generators around. There are a few things to consider when you want to buy a generator and we go through the important ones below. When it comes to choosing a generator, the first thing to think about is how many devices or appliances will need to be powered by it, and also if you’ll want sensitive electronics to be powered by it, in order to figure out how many watts are appropriate for your needs.

As a rough guide, if a device you need to power uses 250 running watts, its starting wattage is around three times that number. Multiplying 250 by four (3x starting watts and 1x running watts) will show that you need a generator with a minimum of 1,000 watts. As far as the generator noise level is concerned, the generators on our list of the best range from 48 to 60 decibels; to give you an idea of how quiet that is, the average home noise is 40 decibels, and 60 decibels is akin to the noise level of background music or normal conversation.

Another factor to consider is whether your quiet power generator of choice is CARB-compliant, which means it meets the standards of the California Air Resources Board for better air quality. In addition to choosing a carb-compliant clean power model, it’s best to opt for a fuel-efficient generator, with lower fuel consumption, and preferably a fuel economy mode.

Conclusion

Many of the modern gas generators come with an eco-mode which helps your pocket as well as the environment. An easy-to-read fuel gauge or external fuel indicator will help you keep tabs on the fuel efficiency and consumption. There are a number of tried and tested quiet portable generators on the market and we've listed the top options below so you can finally stop worrying about disturbing the neighbors, or having that constant buzzing background noise when running your portable generator for long periods.

Related Resources

For tasks like powering lights, charging devices, and keeping the refrigerator on—all while keeping as quiet as possible—a smaller generator will do just fine, but if you want to operate heavy-duty tools or machinery—or even your whole house during an outage—you might want to opt for a bigger model with 9-12,000 peak watts.
