Among the various types of generators available, most homeowners tend to prefer either conventional generators or portable inverter generators. Inverter generators are superior in many aspects, with noise level being one of the key differences between the two.
What sets the inverter generator apart is its design and operation. While both the conventional and inverter generators produce the same amount of power and are powered by engines running on fossil fuels, the inverter generator is significantly quieter. This difference lies in their distinct design parameters and working mechanisms.
Read on to discover the root causes of generator noise and how the design and operation of inverter generators help to minimize it.
Why Does the Generator Produce Noise in the First Place?
This is due to the mechanical rotating and moving parts, which are the primary sources of the noise.
The engine is the most crucial component of any generator. It operates by igniting fuel, which then powers the pistons, driving the rotational motion inside the alternator to produce electricity. Most of the noise comes from the numerous small explosions of fuel burning inside the engine. While companies implement measures to reduce this noise, they can’t eliminate it entirely, especially in open-frame generators. To achieve a supply frequency of 60 Hz, the generator must maintain a constant speed of 3600 RPM. This continuous operation requires the engine to keep running and burning a consistent amount of fuel to sustain the necessary speed and frequency.
Additionally, apart from the internal combustion engine, the friction between moving parts generates a significant amount of noise.
The Noise Problem with Conventional Generators
Conventional generators, often known as traditional or standard generators, generate power using a mechanical alternator. This involves a coil rotating within a magnetic field to produce electricity. However, this process also creates a substantial amount of noise, typically ranging from 70 to 90 decibels.
To put things into perspective, an average conversation between two people is about 60 dB, while a lawnmower or vacuum cleaner can reach up to 90 dB. Noise is a significant issue with traditional generators. This noise can be quite a nuisance, especially in residential areas or during activities like camping or RVing. Traditional generators can disrupt the tranquility of nature or the comfort of your backyard.
What Makes Inverter Generators Quiet?
One of the key design and operational differences between conventional and inverter generators is the level of noise produced. Inverter generators are inherently quieter due to their smaller, quieter engines compared to those in conventional generators. Additionally, unlike conventional generators, inverter generators do not need to run continuously at a constant speed to maintain the output voltage frequency.
The consistent frequency is achieved through the operation of the inverter generator. The engine drives the alternator to produce AC electricity, which is then converted to DC and subsequently back to AC. This entire process is managed by a microprocessor, ensuring stable frequency output.
The microcontroller adjusts the motor speed based on the load, reducing noise while maintaining a consistent frequency.
This means that one of the standout features of inverter generators is their lower noise levels. They are equipped with advanced noise-reducing technologies and high-quality mufflers.
Additionally, these generators are encased in noise-absorbing, high-quality materials.
Real-World Applications of Quiet Inverter Generators
The quiet operation of inverter generators makes them perfect for a wide range of applications, such as:
- Camping and RVing: Inverter generators are ideal for outdoor enthusiasts who wish to enjoy the tranquility of nature without being disturbed by a noisy generator.
- Home backup power: Inverter generators provide homeowners with a dependable source of backup power during outages without the noise and disruption associated with conventional generators.
- Outdoor events: Inverter generators are perfect for outdoor occasions like weddings, festivals, and concerts, where maintaining low noise levels is essential.
- Mobile Detailing: An Ideal Companion for Inverter Generators.
Mobile Detailing: An Ideal Companion for Inverter Generators.
Mobile detailing businesses offering on-site car washing and detailing services can significantly benefit from the quiet operation of inverter generators. These generators enable mobile detailers to power their equipment without causing a disturbance, allowing them to work in residential areas or at outdoor events without concerns about noise complaints.
Can a traditional generator be as silent as an inverter generator?
No, you cannot make conventional generators as quiet as inverter generators. The difference in their working mechanisms creates a significant disparity in noise levels, as explained.
While the noise of a conventional generator can be significantly reduced with some external methods, it will still be louder than inverter generators. If you enclose the entire generator in a casing, you’ll need to account for air vents and exhaust vents. It’s important to note that exhaust pipes are the second loudest part of the generator.
Conclusion
Choosing inverter generators on the market is an option because they are quiet and portable. They operate quite smoothly and are fuel-efficient. Engines developed for inverter generators are inherently quieter than engines for conventional generators. They also come with additional attachments to reduce noise further. They are designed for usage at home and when camping. The initial cost is significant, but you gain the power and silence to enjoy nature. Let’s choose your generators here.
