What Is the Difference Between an Inverter Generator and a Conventional Generator

Difference Between an Inverter Generator and a Conventional Generator?

It is true that many kinds of generators are clearly labelled portable generators, but there are several distinctions between generator types when it comes to technical specs, design, and usage. One of the main differences between a traditional portable generator and an inverter generator is that the latter is able to convert electrical energy into electrical power.

However, inverter generators are often found on lists of “best portable generators” and “top portable generators” amidst their main differences. The reason for this is that inverter generators are typically lighter and lighter than significantly bigger high powered portable generators.

Both kinds of generators have their advantages and disadvantages. It all depends on what the generator will be used for to determine which benefits outweigh which disadvantages.

Conventional Portable Generator:

Mobile fossil-fuel-powered units are usually meant when referring to portable generators, which can be moved around. These have been the most popular generators on the market right now.

An electric generator is indeed a fuel-powered engine with just an alternator that produces electricity. Diesel fuel and propane are the most common fuel kinds for portable generators.

Hybrid generators are available on some portable generators, but not all of them. There are two fuel types available for the engine, generally gasoline as well as propane.

The primary feature of a traditional portable generator is indeed the motor speed and the resulting electric power output. In order to create 120 volts & 60 Hertz, a traditional fuel-powered portable generator is developed to function at 3600 pm.

Often these fuel-powered portable generators, on either hand, can’t keep a stable 3600 revolutions per minute. Voltage and Hertz vary wildly as a result.

Harmonic distortion would be the term used to describe these fluctuations. Fuel-powered portable generators do not even produce ‘clean electricity because of the constant fluctuations in electrical output as well as elevated harmonic distortions.

Computers, DSLR cameras, mobile phones, and other electrical devices that require a lot of power should be powered by clean energy. Fuel-powered portable generators are indeed noisy because they are unable to maintain a steady 3600 rpm for long periods of time.

Energy and run-time are directly correlated with such a fuel-powered mobile generator’s capacity to carry out its intended task. Power and run time increase with larger gas tanks in most cases.

Consider the size and weight of portable generators, which can generate up to 10.000 watts of power. However, even after their weight and volume, the majority of portable generators still have rims and a handle.

Inverter Generator Working Procedure:

Compared to conventional portable generators, inverter generators have a slightly more complex mechanical design. Delivering a final electrical output involves more components.

Many inverter generators are also powered by fossil fuels, such as natural gas and propane. Inverter generators have just a power pack, alternator, as well as inverter furthermore to the gas tank.

When the engine is running, it produces a high-frequency AC current, which the alternator converts into DC current. By using an inverter, you can convert DC into AC current.

Because there is less rhythmic distortion, inverter generators are referred to as ‘clean electricity. When using inverter generators, you can expect the same quality of power generation that you get from your main supply electrical supplier.

Two factors make clean electricity possible. When an inverter generator starts, it has a high-frequency AC current that produces more electric power.

Another factor is the reversal of the AC voltage from DC voltage to AC voltage. The inverter generator’s mechanics have more influence over the AC frequency, allowing it to produce a very steady sine wave.

Electricity output can be more precisely controlled with inverter generators, making them more energy-efficient. It can preserve 3600 rpm while adjusting its voltage to the precise needs of the integrated load.

Another of the principal factors inverter generators are quieter than traditional portable generators is because of the steady current.

Inverter Generator & Conventional Portable Generator – Key Differences:

The major distinction between traditional portable generators and inverter generators are summarized in the following chart. You’ll notice that there are mechanical variations and secondary variations that are a consequence of the mechanical variations.

A mobile fuel-powered generator and then an inverter generator operate differently, allowing for different engineering and use options.

  • Current – 

As far as technical differences are concerned, the main one is the type of electricity produced. When compared to traditional generators that only produce AC electricity, an inverter generator produces three-phase electricity (high-frequency AC to DC back to a stable AC current).

For this reason, inverter generators are regarded as clean electricity sources because of their steady sine wave. For vulnerable electronic devices like a cell phone or a computer or tablet, this implies there is negligible harmonic distortion.

As a result of this, a traditional mobile generator has a much messier sine wave, resulting in far more harmonic distortion. But besides being a viable power source for several electronic devices, this category of current can harm more delicate smart equipment with microprocessors.

  • Fuel Efficiency – 

Inverter generators can’t match the power output of conventional portable generators. For example, fuel tank size and physical differences in electricity production play a role in this.

The ultimate AC current produced by inverter generators seems to be more energy efficient. For example, the motor of an inverter generator automatically switches to the load, which is not possible with a traditional portable generator.

Inverter generators have a higher fuel efficiency, allowing for a smaller fuel tank. Due to increased energy efficiency, less fuel will be required for the same run time, allowing for a relatively small fuel tank to be used.

Due to the fact that conventional generators use much more fuel, they often seem to be bulkier. This bigger fuel tank does, nevertheless, allow for a higher power output, which is a plus.

  • Portability – 

Electric generators powered by an inverter are much more portable than those powered by conventional energy sources. In this case, it’s all about the amount of power that they generate.

As a result of a significantly bigger fuel tank and engine, traditional generators that generate more power require more substance to house them. There are a few reasons why inverter generators are more powerful and lighter than traditional portable generators.

The bigger traditional generators have rims and handle to make them portable. The fact that many portable generators still weigh more than 100 pounds makes this a difficult task.

Generators that use inverter technology are smaller and since their fuel tanks are relatively small and also because their generated power is lesser. Inverter generators are quite often lightweight to be handled by hand with a handle.

Final Words: 

An inverter generator is the better choice depending on the generator’s intended use. Regular campers or road trippers may prefer an inverter generator, while those who need to generate electricity at a residence or a work site may prefer a traditional portable generator.

Take a moment to consider where and how much electricity you’ll need. If you’re having a hard time deciding, this is the best way to go.
