How Does An Inverter Generator Work?

One may ask, how does an inverter generator work? Inverter generators are built almost the same as other generator models. Normal generators are running; they produce AC power, which is then converted into DC power.

However, the inverter within the generator converts the power back into AC once more. Both generators start with producing standard power, but the similarity ends when the inverter converts the power to raw high voltage power. This is because the inverter generator has a microprocessor that is specifically engineered to complete the conversion.

The inverter generators are designed to produce clean, consistent, smooth, and stable power. Its power can also be compared to the one produced and supplied by utility companies to your homes.

Inverter generators are becoming quite popular, and most people are choosing them over conventional generators. However, before you consider investing in an inverter generator, it is essential that you understand how it works and its benefits. The article on the top 5 best inverter generators can act as a good guide.

Benefits of Inverter Generators

When packing for a weekend camp trip, packing a heavy generator at the back of your van can be a painful adventure. However, that is not the case when you invest in an inverter generator.

The weight of most generators is determined by their durability, strength, and other reliable components. But, when it comes to inverter generators, they are always lighter than other typical portable generators.

Therefore, it will ease your packing process and guarantee you can take the generator with you whenever you wish. However, the lighter the generator also means you get less power.

Therefore, you are buying; it is essential for you to put into consideration the amount of power you want for your adventure. This can be determined based on the type of equipment you wish to power.


Inverter generators are designed with an idle control feature, making them consume less gas compared to other models. However, this economy mode or eco-throttle feature is placed differently on different brands, with some as an in-built feature while others allow you to turn it on or off from the control panel.

The idle control makes it possible for you to adjust the inverter generator’s speed to your specification and only burn the required fuel to power your appliances.

The inverter generator can run on varying power at minimal fuel consumption, unlike the typical generators.

Therefore, you are guaranteed that you can comfortably run high-powered appliances at high speeds and low fuel. This also indicates that maintaining the generator is easy.

Super Quiet

how does an inverter generator work?

When you think of generators, it is obvious you don’t expect them to be quiet. However, things are different when it comes to inverter generators. They are designed with an alternating sound enclosure that helps in minimizing noise. Therefore, it is easy for you to walk and communicate with a friend positively.

Most inverter generators produce a sound that ranges within 50-60dB, which is equivalent to office noise, normal conversation, or inside a running car noise. In other words, when an inverter generator starts while you are in a middle of a conversation, you will not have to stop talking or rather change location.

Instead, you will keep active communication with your friend with minimal noise interruption from the generator noise. Additionally, when on a camping adventure, noise-canceling generators come in handy. It allows you to enjoy peaceful rest while still powering all the appliances.

What’s The Difference Between A Conventional Generator And An Inverter Generator?

Several generators are labeled portable, but they all have a difference in design, technical specifications, and uses. Inverter generators are quite different compared to other types of portable generators.

Most inverter generators are super light, making them convenient to carry from one location to the other, unlike other conventional portable generators.

The inverter generators are also designed to operate heavy appliances and adjust operating speeds to meet your respective specifications, which conventional generators cannot do. Therefore, they allow you to experience consistency in power production and maintain fuel efficiency.

Another significant difference between an inverter generator and a conventional generator is connecting with similar generators. When you want to power many appliances, but your generator is smaller and only produces limited power, you can boost your power by connecting it to a similar generator.

Most inverter generators come with a special cable that allows such connection, which you cannot find in normal generators.

Inverter generators are the only true portable generators, thanks to their lightweight and compact designs. The wheels are super strong and can withstand any terrain allowing you to get to your destination freely regardless of the challenges.
