What Is An Inverter Generator – Resolve Your Query

You might have heard about generators, but it might seem new to you to know what is a generator inverter. Let’s discuss this in detail!

The standard generators might be unable to run your hairdryer, refrigerators, and Air conditioner safely; for that reason, the power inverter generator has hit the market with its high-efficiency safety feature to ensure device safety along with the generator safety.

We have a well-summarized handy guide that will provide sufficient knowledge required for understanding an inverter generator to solve your queries.

What Is An Inverter Generator

What does an inverter generator mean? Here is the main confusion you might get stuck in. Are you sure your blow-dry will work efficiently and safely if you opt for a generator?

What if you are going to a party and left without the blow dry due to a sudden blackout? How to tackle it? In these cases, an inverter generator suits you best.

The inverter generator is a powerful, compact, quiet, and energy-efficient device that opts to invert electricity for powering your sensitive devices with clean and safe power, unlike a standard generator that may require an extra inverter module for the desired action.

If you want to know more about generators so, you can click here to explore the different types of generators.

Types Of Inverter Generators:

There are two prime subtypes of inverter generators, including 

  • Closed-frame inverter generators
  • Open-frame inverter generators 

Closed-Frame Inverter Generators:

The close-frame generators possess a protective shell that absorbs the excessive noise produced by the generator.

Their compact and portable nature makes them easily opt for emergency conditions empowering small-load devices with safe charging. They are the quietest generators in the world on inverter generators. 

Open-Frame Inverter Generators: 

Open-frame inverter generators are 50% quieter than standard generators but are as efficient as close frames in providing safe power generation with even the ability to power larger devices. Isn’t that amazing! 

It lacks the protective insulation covering that opts to absorb the noise. So that’s why the frameless ones are louder than the closed frame inverter generator but still quieter than the standard ones.

Select the type as per your desired criteria.

Main Parts Of Inverter Generator:

These are the components of portable generators. Each component is in charge of a specific task that, when combined, produces the desired AC needed to power daily appliances.

  • A fuel tank (gasoline, natural gas, propane, diesel)
  • Internal combustion technology
  • Alternator (also known as generator head or gen head)  a. Starter b. Rotor 
  • Computer system 
  • Rectifier (for rectification purposes)
  • Inverter (inversion process)
  • Voltage controller
  • Power outlets

How To Use An Inverter Generator? Things You Should Know

Let’s discuss here its detailed procedure.


  • First, choose the ideal location for your inverter generator to prevent dangerous pollutants from building up within your dwellings. It releases deadly CO carbon monoxide fumes. Always pick a great, open area, preferably outside or on the high ground beneath the sky.
  • Depending on the sort of generator that works well, make sure there is enough supply of fuel. Gas has most frequently been chosen as a mechanical source. Diesel, propane, and other fuels are also sources.
  • Once the oil has been inspected, turn on the gasoline line. Change the choke button and start the generator. Don’t forget to press the button before kicking the generator to start it.
  • Fit the extension cord’s one end into the outlet and its other end into the outlets of the gadgets that need power. The extension cord can be connected either before or after the start.

Hurrah! You did a fantastic job! While you wait for the power to come back, get a cup of tea and unwind by listening to your favorite music! The inverter generator will allow the safe charging of sensitive devices like phones, tablets, laptops, hairdryers, etc.

How Does An Inverter Generator Work? Check It Out!

To know the working of the inverter generator, you must be aware of how a standard generator works for producing electricity. 


Now we describe the procedure step by step.

Electromagnetic Induction:

Like the standard generator, it also operates by the mechanism of electromagnetic induction that requires the generator fuel for mechanical energy and the alternator with rotor and stator that helps produce electric current within the magnetic field.


Moving the coil in the magnetic field produces electricity that might be gone under safety features, but it is still not that much to be safe enough for sensitive devices.

It still has a higher total harmonic distortion (THD). It’s a parameter to check how much cleaner the electricity is for sensitive devices. 

For that purpose, the inverter generators get the job done. Unlike a standard generator, the inverter generator allows the alternating current produced by the alternator to enter a rectifier, an additional device that opts for converting the AC to DC. 


After rectification, the DC is inverted back to AC by a pre-installed computer system inside the generator. This process is called inversion.

Due to this extra step, the electricity gets cleaned before sending it to the control panel.

This feature is missing in the standard generator; these generators are inverter generators. The inverter generator’s THD is very low, making it a better option for sensitive devices. 

Supplying Of Safe Current To Outlets:

After inversion, the same process repeats as the standard generators, and the electricity is sent to the outlets to be used by the devices.

Now your devices are free from any damage by uncertified electricity. Still, as you know, this electricity will be a much cleaner and safer one.

THD Of Standard Generator Vs. Inverter Generator:

Most inverter generators opt for pure-sine-wave, limiting the THD up to 1% in almost all cases. But, THD will rise to 25% for the traditional standard generators depending on the situation. So, the lesser the THD, the better and highly safe the device. 

Now, move on to a detailed review of the pros and cons.

  • Ultra Quiet
  • Standard Decibel
  • High Fuel Efficiency
  • Lightweight and Compact Size
  • Easily Available Backup Source
  • Cost
  • Manual Start
  • Limited Usage

Ultra Quiet:

Sitting miles away but can still hear the noise of a standard generator, it’s not for the inverter generator, especially the closed frame inverter generators.

They possess a protective covering that absorbs the high-decibel sounds, making them suitable for home use. So, you can be sitting along with an inverter generator and still enjoy your family’s company.

Standard Decibel:

They function at a very low volume between 50-60dB, making them a perfect choice for sensitive gadgets, trucks, and work sites.

These generators have a sound-attenuating enclosure feature responsible for reducing unnecessary noise. 

High Fuel Efficiency:

Inverter generators are eco-friendly devices that ensure low fuel efficiency and standardize fuel usage based on device power consumption.

They utilize high fuel without standardizing it. If fewer devices are operating, the inverter generator will modify the fuel consumption, unlike the standard generator that lacks such features. 

Lightweight And Compact Size:

The lightweight and ultra-compact size make them highly portable and regular-use generators to safely charge your sensitive devices easily and efficiently.

You can opt for them in emergency conditions where bulkier generators might be difficult to operate, such as CPAP and nebulizers. Depending on the size, you can lift it and put it even in your backup.

Easily Available Backup Source:

Portable generators’ main benefit is that they are widely available. In the case of a power loss, it offers a rapid portable power backup source.

A portable generator will always have your back and take care of your power outage concerns, whether you’re at home or traveling outdoors.



To opt for this sophisticated device, you should lose your pockets regarding its cost. Their high efficiency, safety features, and extra built-in computer operating system make them high-cost devices.

They are worthy enough because they clean up your electricity better than any standard generator. 

Manual Start:

You will need to follow a manual process to start and stop the device, unlike fitted generators that do so automatically.

Limited Usage:

They are efficient, safe operating generators, but you can power up the whole of your house or work site using the inverter generator. It is for sensitive gadgets that can get damaged due to the raw electricity of the standard ones.

The devices that won’t care about getting damaged even work well with an inverter generator. So, don’t opt for whole-house; you may get in trouble!
