What is an Inverter Generator?

Before we start with what the inverter generator is, let’s first clear the air. You must be asking, but there are two words here that on their own are machines and make total sense. Inverter and Generator. Now, these word are combined to form a single functional machine. Now you must be confused. Easy, read on.

Most a people use the words inverter, generator and inverter generator interchangeably. This happens because they don’t know the differences between the three. Read on to know the difference and the right word to use.


This machine has been in use for quite some time. They consist of a source of energy, majorly fuel such as diesel, gasoline or propane. The fossil fuel is the source of energy that powers a mechanical motor directly attached to an alternator. The alternator in return produces electricity.

A precept of the motor rotating at a constant speed must be maintained. The speed is normally 3,600 rpm. This is to make sure a standard current to successfully run household effects is produced.


An inverter gets power from a static direct current source of power. These may be a car battery or a solar panel. As the name suggests, its work is to invert or reverse the direct current (DC) into alternating (AC) power. The converted AC can be manipulated into any required voltage and frequency with the use of appropriate gear.

AC power is the power that we use in operating the usual home gadgets.

Inverter Generators

Inverter generators are a recent invention. Here, advanced electric circuitry and magnets are used. It is a 3-phase machine, meaning that there is conversion of power in three stages.

  1. There is output of AC current, just like most traditional generators.
  2. The AC current is converted to DC current
  3. The DC current is then ‘inverted’ to clean AC at the required voltage and frequency.

This unit puts into use technologies of both an inverter and a generator. This is why it is called an Inverter generator.

At times you may want to sound cool when talking with colleagues and may be tempted to contract the term ‘inverter generator’ to ‘inverter’ or ‘generator’. Well, don’t, it may lead to confusion. All these are different as seen in the precise explanation of the differences.

For your information, Inverter Generators are also called I-Generators. You want to be cool or just quick in mentioning inverter generators? Use the term instead of inverter or generator to mean inverter generator.

To fully understand what an inverter generator is first you need to know that there are other generators in existent. The conventional generators.

These conventional generators include the simple traditional inverters. Mostly, these types are not good enough for most applications at hand.

However, there are some conventional generators (electric generators), which have been tried and proved to be true. Can be of help when it comes to some power requirements but not as good and enough as an inverter generator.

Inverter generators have the following benefits thus proof that they are more reliable and convenient when you need power be it for your home or company.

Benefits of Inverter Generators

Uncompromised Power Output Quality

Its precision and efficiency ensures power is always closer to line power. The produced power is reliable, just like the power from a nuclear plant.

Lighter, Smaller and Portable Size

Advanced technology is highly utilized when designing the generator. This makes sure the size is put into consideration. Yet the efficiency is not compromised. The inverter technology is combined with parts of the engine and the generator. This allows the inverter generator to be even smaller.

The generator weighs between 30-50 pounds. This means that they are easy to transport and store. How about fitting one into your car or boat and use it while on a hike. Yeah, sounds good.

Fuel Efficacy

A specific technology is used to automatically, without fail adjust the engine acceleration to produce a power output only needed for the specific application at hand. This way fuel is saved. Traditional generators run at 3,600 rpm at a frequency of 60 Hertz per cycle. Inverter generators can run at lower rpm and still maintain the required frequency to produce power to run the application at hand without stopping at any given moment.

They don’t have a big heavy fuel tank. We are sure you do expect the generator to have a shorter run time. You are wrong. The engine is fuel-efficient. They have the ability to adjust the engine speed depending on the load at hand. Fuel-efficiency means low exhaust emissions for healthy environment.

The generator can save up to 40% of the fuel cost. Be smart and save more by using this generator.

Quiet Running

Traditional generators make so much noise. You can barely focus on what you are doing. On the other hand Inverter generators are designed to work quietly. The engine here never runs at full speed but produce the needed power. This makes it quiet.

They can quickly change the electrical trends of the produced power using inbuilt micro-processers and electronics. This means that the engine can choke back when the load is light and substantially reduce noise.

Surprisingly, conventional generators are rated at 75 decibels which is equal to the noise of jet engine. Such a nuisance. On the other hand, inverter generators make little noise, so little in that it equals to the normal human conversing.

Also, special silencing materials, cooler engines, mufflers and technology that dampens sound are used to make it quieter.

Parallel Compatibility

Inverter generators can be paired with another identical one in terms of size unit. This is mainly applied when you need more power. This application allows you to several smaller, lighter generators to do the same work that would have been done by a big bulky generator.

Reasonable Price

With all these advantages you must think that the price is as that of a rocket, right? Surprisingly nop. Though it is slightly higher than that of a conventional generator. But, hey think of this. How much will you save on fuel? A whopping 40%. This makes it cheaper in terms of maintenance. You are guaranteed high quality power.
