Inverter vs Silenced vs Conventional Generators

Comparing Inverter, Silenced and Conventional Generators

For people who are new to the market of generators, it can be hard and time-consuming to get a better idea of existing differences. Here we will explain the main differences among different types of portable generators and provide the greatest benefits of each category involved. It’s important to make a good comparison of all available types to choose the right one.

Conventional Generators

Nowadays, these generators are used by most people because they’ve been around for a long time, and the main principle of their work remains almost the same. They run on gasoline diesel and propane, and their motors run at some constant speed to provide users with the necessary electrical current. The rpm of their engines shouldn’t fluctuate, otherwise, it will change the frequency of electric outputs.

Silenced Generators

As their name suggests, these devices are entirely enclosed in some robust and sound-proof enclosure, which is called an acoustic cabinet. Their noise levels are smaller than the ones produced by framed conventional generators, but they are still higher compared to inverter generators.

Inverter Generators

They are designed according to the recent technology that was enabled by state-of-art magnets and advanced electronic circuitry. This technology outputs the AC current, just like many conventional generators, but it’s converted to the DC voltage to be inverted back to the clean AC one, and this is how these devices got their name. The greatest benefit of using them is that they maintain the constant flow of current to different appliances.

Tips on How to Choose the Right One

Your final choice depends on a set of important factors, such as the appliances that you want to use and your available budget. You need to keep in mind many important considerations and decide whether a given generator type fits your finances.

Their Portability, Weight and Sizes

Most modern models of inverter generators are quite lightweight and small, and this is what makes them simple to stow away and transport because they can easily fit in a car, RV and so on.

When it comes to conventional generators, they are bulky and heavy because of their wheels and metal frames. In theory, they are portable, but it’s hard to move them, and they also lack the important convenience factor offered by lighter and smaller inverters. Silenced generators are the bulkiest because of their acoustic cabinets.

Running Times and Fuel Efficiency

Running times depend on the size of fuel tanks, and any of them can be attached to generators, regardless of their type. Inverters are still considered to be more fuel-efficient because of their engine speed adjusted based on the power load required. Conventional devices run at 3600 rpm, no matter what their power load is, and this means that possible fuel savings are great.

Noise Levels

This aspect is something that separates a few categories of generators. For example, inverters are created to be pretty quiet because quieter engines, sound-dampening technology and special mufflers are used to decrease noise levels to as low as possible. Conventional units always run at their constant speed to provide users with a stable flow of electricity, while inverters adjust their electrical characteristics of the power they produce through special electronics and microprocessors. Their engines throttle back when their load is light, thus, saving a lot of fuel while reducing noise levels. This means that those inverters that run low are equivalent to people conversing. Conventional models may have the same noise decibels as chain saws, while the silenced ones have the same engines as these ones because they run at a constant speed, but the main difference is that they are much quieter because of their acoustic cabinet that dampens sounds.

Maximal Power Outputs

Silenced and conventional generators are available in any possible size, while inverters are more focused on such important characteristics as their quiet operation, convenience and portability, but it also means that their maximal output capabilities are limited because they come only in 1,000-4,000 watt versions

Quality of Produced Power

Silenced and conventional generators are all about the engines connected to alternators that run at the speed that produces the necessary AC frequency, despite its load (this is what increases engines throttles up to keep speed levels the same). Besides, the outputs of alternators are directly connected to loads with no processing. People should be familiar with the inverting technology to understand why the quality of produced power is an essential aspect when shopping for the next generator.

The engines of inverters are connected to their effective alternators that produce AC electricity, like conventional generators, and then they use rectifiers to convert it to DC while capacitors are used for smoothing it out to specific degrees. After that the DC power is inverted into clean AC power at the necessary voltage and frequency. This is how this system offers its reliable and consistent power independent of engine speeds, which results in a cleaner power compared to conventional models and the same electricity quality that consumers get from electric companies.

Why is this aspect so important? There are more and more items that use different forms of microprocessors, including TVs, phones, computers, printers, gaming consoles, DVDs, power tools, kitchen appliances, etc. All of their microprocessors are quite sensitive to the electricity quality that they utilize. The use of the power that is unclean often makes these units malfunction and can even damage them. That’s why all of the applications that use any sensitive electronics will benefit from the clean power produced by inverters.


Conventional generators have many benefits, including higher power output and affordable price, because their simple and functional construction makes them cheaper and less expensive to repair. Of course, silenced generators are more expensive because of their extra acoustic cabinets included in the design. It’s true that inverters come with a set of essential benefits over other models, including their quiet operations, convenience, design, fuel-efficiency, controlled power outputs and others. In terms of their prices, they are higher, but it’s important to evaluate the role played by every factor when making a final choice. Finally, consumers should take their available budgets into consideration when making their next generator purchase.
