A silent generator - DENQBAR makes it happen!
Silent generator: that doesn't have to be a contradiction in terms!
At first, it sounds like a complete paradox when you read power generators and the word "silent" in the same sentence and context. So when is a power generator considered silent?
A power generator is considered silent if it produces the lowest possible noise level during operation. The noise level of a generator is usually measured in decibels (dB) and can vary depending on the type and size of the generator. In general, an inverter generator with a noise level of 50 to 60 dB is considered the most silent type of generator. Conventional generators, on the other hand, can produce a noise level of 70-90 dB or more. It is important to know that even the quietest generators produce a certain amount of noise. Therefore, it is important to choose a generator with a noise level that is suitable for your needs and environment.
A mobile power generator is a great thing to have. Thanks to it, you can be independent and have access to electricity even in places where no one else has it. Whether you're exploring the world in a motorhome, at festivals, relaxed camping, for DIY enthusiasts, on boats, in the garden at home, during a blackout or as a power source on construction sites - the fields of use are almost unlimited.
Especially if you are not traveling alone in the most remote corners of the world, the power generator should be silent. After all, you want to maintain a good relationship with your neighbors or other people at the camping site or festival grounds.
In the following, we have collected some tips and tricks to ensure that a power generator runs quietly. In this guide, we also provide many useful tips on how to pay sufficient attention to the issue of operating volume when making a purchase decision. Have fun reading!
Why do inverter generators work so quietly?
Before answering this question, we should briefly explain what an inverter generator actually is. This innovative technology reliably converts direct current into harmonic alternating current. This provides the connected consumers with a perfect and clean sine wave voltage in mains power quality.
And what exactly are the benefits? Well, because no feared voltage fluctuations can occur with an inverter generator, even electronically sensitive devices (e.g. laptop, TV set or hi-fi system) can be connected without any concerns. Conventional generators without inverter technology, on the other hand, would most likely cause serious damage to the connected appliances.
A key feature of an inverter generator is that the combustion engine and the generator work completely independent of each other. This makes it possible to run at different frequencies. An inverter power generator is therefore able to optimally adjust the engine speed downwards in partial load operation (the so-called "eco mode") to the amount of electrical energy required for consumption. The owner of the device benefits from this in several ways: a down-regulated inverter generator is silent and also consumes less valuable fuel. No conventional power generator can keep up with this.
The perfect design for a silent generator
Unfortunately, even the best engineers and product designers cannot override the rules of physics: The combustion process in the engine of a generator will never run completely without a certain amount of noise. What they can do, however, is to ensure that the generator is designed to operate as silently as possible.
Encapsulated (i.e. fully enclosed) inverter generators have also established themselves in this respect. These models impress with significantly better soundproofing properties and effective insulation compared to open frame devices. So if you are interested in a good relationship with your neighbors or don't want to make any enemies during your camping vacation, you should definitely opt for a device with inverter technology, as these generators work quietly.
Can fuel have an impact on whether a generator is silent?
Mobile power generators are usually operated with the following types of fuel: Petrol, diesel and, more rarely, gas. Of course, each type has its own strengths and weaknesses. The biggest differences can be found in the purchase price, running costs, noise levels, running behavior and potential use cases.
If you want the generator to work silently - because you are an enthusiastic camping fan or a festival visitor, for example - you should consider a petrol-powered generator set with inverter technology. These are cheaper to buy and have lower fuel consumption than their diesel counterparts in the same power class. In addition, petrol-powered generators are much quieter and run more smoothly than diesel generators.
What can you do yourself to ensure that the generator runs silently?
Although technicians and engineers have done an ever better job in recent years of ensuring that power generators run silently, as a consumer you like to tickle out the last few percentage points yourself. To do this, you need to think about what the main tasks of the power generator will be and where it will be installed before you buy it.
One effective way of preventing the sound waves of a working generator from spreading as far as possible is to install the generator set in a wooden box.
But be careful: ensure that there is sufficient ventilation at all times and that the exhaust gases are safely vented to the outside. In addition, the temperature in the box should be monitored. It should not exceed 43 degrees, otherwise the engine could become too hot.
If a soundproof box is not an option, there are of course other ways to keep the generator silent. Simply placing it behind a mound of soil, a dense hedge or a small wall can significantly reduce the noise level.
This DENQBAR guide dealt with the question of what you should pay attention to so that your power generator runs silently. It was shown that inverter generators are generally quieter than conventional generators: In eco mode, the engine automatically adapts to the amount of energy required by the connected consumer. It is only logical that a down-regulated engine is quieter than one running at high speed.
It was also pointed out that encapsulated power generators have better sound insulation than open frame devices. The use of petrol fuel also has a positive effect on the silent and smooth running of the power generator. In addition, a conscious choice of location can achieve a lot: without much effort, the device quickly disappears behind a mound of soil or a small wall, but the results are all the more impressive. This way, inverter generators work almost as quiet as a whisper.
