Ask some people for their definition of  a portable quiet generator and many will say  that is the type that is easy to carry around and also emits low noise. But ask them what “low-noise” is and many will give vague answers. An undeniable truth is that portable generators have become quiet common.

They come in handy as backup power sources in case of a power outage. They can be used in remote areas that aren’t connected to the electricity grid, and are also used during emergencies when power lines get damaged. Furthermore, the power generators are common in tailgating, camping and concerts.
While their importance can’t be underestimated, we can’t deny the “inconvenience they cause due to noise.” Have you ever tried to sleep while a generator is running, or tried to concentrate when the neighbor is operating his noisy unit? If you have, then you obviously know the inconvenience that comes with it.

In fact, due to the noise produced, many regions have regulations about running these accessories. You are only allowed to use a type that won’t cause any noise pollution and inconvenience to the people around. Standard generators are much louder and the noise decibels are normally above about 70 decibels. The noise decibels emitted by the silent type is usually between 51 db and 60 db.

The following Information is designed to help you make a more clear and precise decision in obtaining the perfect quiet generator for your needs.

INDEPENDENT REVIEW

“I had been looking for a generator that would provide stable and reliable electricity in case of any power outages. I was particularly interested in a portable unit that I would be able to carry around when I went camping with my family or friends. After weeks of online research, I was overwhelmed by the numerous models available and the varying reviews on each model.

My neighbor recommended the Briggs and Stratton 30651 P2200 portable inverter generator to me, which he had been using to power his workshop. I was quite skeptical at first since I had previously purchased two generators that had failed to meet my expectations. I eventually bought the generator and I have been using it regularly for about three months now. My experience with this product has been excellent.

I recently carried it on a camping trip and I was greatly impressed by how much of a quiet generator it was. My friends and I were able to keep our phones and laptops charged throughout the trip. After about 7 hours of use, it ran out of oil and we were able to easily refill the tank and continue using it. The H-type handle at the top and it’s incredibly light weight made it quite easy and convenient to carry around. I would highly recommend this generator to anyone looking for a portable and reliable source of power for any outdoor activities. It will certainly prove to be a worthy purchase.”

MAIN REASONS TO GET A PORTABLE QUIET GENERATOR
1. In Some Neighborhoods, Loud Noise Is Disturbing And Prohibited.
As civilization progresses, the spaces between homes are becoming smaller. However, the power needs continue to increase. And to ensure that they have power anytime including when there is a blackout, many people are investing in portable generators. This enables them to run most electrical devices in the home, office and other places. Sadly, while they improve convenience when it comes to power, generators can cause lots of noise pollution. Imagine you, your neighbor and the other neighbor running generators at the same time? Noise, Noise and more noise is what you get. This can make life pretty unbearable. 
 
To avoid such troubles, people are advised to go for silent generators. The noise of a unit is normally indicated on the sticker on the accessory and it pays to familiarize with what is termed too noisy. In most cases anything above 75dB is deemed too noisy and it is better to always aim for the lowest number.
 
2. There Are Loud Noise Restrictions on Some Campgrounds.
Another area that uses portable generators is campsites. Although people want to become one with nature, many can’t do without the little luxuries in life. While sleeping under the tent, staring at the skies, or enjoying a meal or drink by the bonfire is what many people want, many can’t let go of their phone, tablet, laptop, chargers and other electronics. Many also want to enjoy quality lighting even in the wild, play music from their stereo, use the bread toaster or whip some smoothie or juice with the blender.
 
Running the standard generator, although effective, can be a bit of an inconvenience especially in the peak season. Firstly, the spaces between different groups are much smaller. And secondly, several generators will be operating at the same time. To keep the environment less-noisy and reduce confrontation between the campers, many campgrounds have regulations pertaining to the portable generators. They ask people to carry types that produce the minimal noise possible.
 
3. There Are Loud Noise Restrictions When Tailgating Or At Other Public Events.
Another area where noisy portable generators are discouraged or restricted is during tailgating and public events. Normally, the people will be driving or parked very close to each other. In some instances, the space between the vehicles, camping vans, or RVs will be so little. Now picture you and your group running your generator, the other party a few inches away operating theirs, and the other revelers also doing the same. Instead of the event being fun-filled and exciting, it will be more of a shouting match as you struggle to speak and listen what the other person is saying.
 
When hosting public events such as concerts, social gatherings or in tailgating, the organizers ask the participants to only carry silent generators. This type will work just like the standard type but will produce very minimal noise. Modern types are more efficient than earlier types in fuel efficiency, power delivery, and noise production. It’s also important to regularly service the unit so as to inspect if the muffler which is responsible for containing the noise is in good condition.
 
Benefits of a Quiet Portable Generator
The following are the key benefits of investing in a portable generator:
– Portability: A good unit is fairly-light, compact and easy to carry from one place to another. This provides power anywhere, anytime.
– Reduce Noise Level: Quiet generators produce low noise allowing people to enjoy their experience. There will be no distractions, struggling to hear or having to shout to be heard.
– Maximum Satisfaction: Minimal noise ensures the people enjoy the outdoors better. Top types are very silent and can be used even in very quiet environment even at night.
– Reduce Noise Pollution: Noise is not only a nuisance but can have negative effects on health. Exposure to loud or continuous noise may make a person stressed, depressed or harm the ears.
– Peace of Mind: Due to their silent nature, quiet generators are less-likely to bring confrontation between you and the people around you. You also don’t have to worry about receiving a warning from the authorities.
 
CONCLUSION  
Listed above are some reasons why a silent portable generator is better than the standard type. Due to low noise production, it can be used in camping sites, tailgating, in the neighborhood and other regions without contravening the laid down noise regulations. We also have talked about the benefits that come with a good and reliable quiet portable generator. Its easy to carry around, produces bearable noise, reduces noise pollution that may harm your health, offers you peace-of-mind as well as maximum satisfaction. To get the best service and enjoy the experience, it’s crucial to go for well-known and reputable brands. Also important is buying the units from trustworthy sources.

 

What Actually Makes An Inverter Generator Quieter Than A Standard Gemerator?

There are commonly two basic types of Generators. These are standard generators and inverter generators. The basic difference between these two types of generators is the mechanism in which they operate to generate energy in form of electricity. The Inverter Generator combines the use of both inverter and generator, hence the name “inverter generator”. To clearly distinguish between a standard generator and inverter generator, there is a need to begin by explaining clearly what exactly is meant by both terms-generator and inverter.

A standard generator (often referred to as the conventional generator) is a source of electrical energy that consists of another source of it’s initial energy which it uses to generate electrical energy. This initial energy source may be in form of fossil fuel such as gasoline, propane or diesel. This energy acts as a source of power to a simple motor that is attached on the generator’s alternator.

This makes it produce electricity. In order to produce the desired constant energy, the generator’s motor must operate at a constant speed. For example, in most households that use generators to generate energy, the motor runs at a constant speed of 3600rpm to yield the standard current (120 Volts AC @ 60 Hertz). Fluctuation of the engine’s speed (rpm) leads to fluctuation of the electrical output.

Inverters on the other hand are known to draw power from fixed source of DC such as a car battery and and solar panel (comparatively fixed). The DC power is then inverted into AC power using electronic circuitry. The frequency and voltage of the inverted AC (or rather converted) depends on the equipment used, but the most common one is 12VDC power from boat, car and RV batteries converted into 120 V AC power. This is in most cases the amount of energy required for use in most households.

An inverter generator combines the use of both a standard generator and inverter. They are more recent as compared to both inverter and standard generator. It’s electronic circuitry is relatively advanced and of high-tech magnets. Just as conventional generators, they are three phase and they output AC in the same traditional way, but the resulting current is then converted to DC and thereafter inverted back to fresh AC power which helps to maintain one phase at the required voltage and frequency. this is the reason why they are called inverter generators.

WHY ARE INVERTER GENERATORS QUIETER THAN STANDARD GENERATORS?

The two categories of generators are especially distinguished by the issue of noise they produce while generating electrical energy. The first reason is obvious -inverter generators are made from the ground up to be as quiet as possible. They comprise special mufflers and engines that are comparatively quiet. Sound dampening technology is also employed in making these generators, which substantially assists to bring down sounds they produce to the barest minimum.

Secondly, conventional generators have to run at a constant rate to yield the required amount of energy. For this electricity to be of the desired characteristics, the generator has to run at a constant speed. For example, the rate of 3600rpm produces120VAC @60Hz in most cases. Varying the speed of the engine results in variation of the quality of electric power generated. but this variation is undesirable.  

So the engine must be kept running at full speed, producing loud sound, in order to generate the energy required. In the case of inverter generators, inverters automatically adjust the characteristics of electrical power produced. this technology uses special electronics and microprocessors.

This means that when the load is light, the engine can slow down. in the process, energy is saved and the noise is reduced to a considerable extent. A good example is ain inverter generator that only produces 51.5 decibels while running at 1/4 load (which is a similar decibel level to human conversation). At full load, it only produces 60 decibels. On the other hand, most conventional generators runs at 65 to 85 decibels (average speed).

CAN A LARGE INVERTER GENERATOR BE AS QUIET AS A SMALL INVERTER GENERATOR?

A small inverter generator is quieter than a large inverter generator. This is because a larger inverter generator has a larger engine and operates on a heavier load as compared to the small one. Operating on a heavier load means that more energy is required. Though not similar to the amount of energy produced by any conventional generator, a larger inverter generator generally produces more noise than a smaller inverter generator.

However, the relatively high noise produced by a large inverter generator can be overcome by adoption of parallel operation system in generation of energy. In parallel operation, identical units of inverter generators are paired to double power capacity/power generation.

This therefore means that two smaller and lighter generators can be made to generate amperage and wattage equal to that which a large inverter generator can produce. This is much convenient in terms of portability, noise produced and the size of generators.
Decibel levels of 0-50 are in most cases considered to be quiet. However, it all depends on the circumstances and the context within which the machine that produces the noise.

In a conclusion, both standard and inverter generators are preferred for use under different circumstances. In ruling out which is better, its important to consider all other factors like the cost of buying, transportation and fueling, complexity and simplicity of use by consumers.
