Inverter Generator Vs Generator | Difference Between

In the market, there are two types of generators, regular generator or generator, and inverter generator. One needs to know the difference between two to find out which one is the desired one for the desired task.

Over the years, irregularity in electricity distribution has been increased dramatically because of the high demand and low production rate. That’s what influenced the power generations industries to find an alternative in case of emergency. They have created two main and common technology to distribute electricity is generators and inverters. Both of the useful mechanisms produce electricity using different techniques holding different benefits.

So, here we present an unbiased discussion about inverter generator vs generator to help the people to choose the better option for their work.

Inverter Generator Vs Generator

One may have an idea about generators but may have no idea about how it works. To know about the generator one must know the working flow of the generator. The generator creates electricity by converting rotating energy. However, the portable generator uses an engine, normally runs by gasoline, diesel, or propane. This produces an alternative electricity current or AC. AC is the electricity people get from the utility company for home and business.

To produce DC there needs a power inverter generator which is an electric method. To convert the direct (DC) current into alternative current (AC) one needs to use a power inverter which is an electronic method.  By drawing power from a power source such as a solar panel and using an electronic circuit it inverts the current.


In these terms, a generator is an electrical device that converts mechanical energy extracting or gained from any external source into electronic power. Instead of producing direct energy, it works on the fundamental principle of electromagnetic induction. It only prepared electrical energy when it gets driven at an exact speed by any prime movement, like a diesel engine or steam, air turbine. During a power, shutdown generators are one of the most useful devices around the whole world. A generator can produce energy from many different sources of mechanical energy like air turbine, gas turbine, air turbine, water turbine, diesel, internal combustion engines, and so on. The DC power is produced mainly used in power plants, mobile equipment for a communication system, and electroplating applications.

However,the generator can be of different types based on the fuel it used.

  • Gasoline: Known as a gas generators, they are super sufficient, easy to use, user-friendly, and reliable. The generator is not complicated at all. If one has a minimum amount of idea they will not any mechanical help with any issue of the gas generator. But the problem is gas is hard to store without a fuel stabilizer. It is hard to fuel the generator. The maintenance of the gasoline generator is complicated.
  • Propane: Ensuring long demanding life propane is easy to store. The propane burns pretty clean so there is no chance of a spill. One doesn’t have to clean it on regular basis. But in terms of efficiency propane is left behind gas. Also, the propane engine is very complicated, hard to fix, may not be user-friendly.
  • Dual Fuel generator: This generator is a lifesaver. The dual-fuel features allow the user to use any of the available fuel to run the generator. That means in a power loss situation one will be perfectly ready to light up the house without hassle.

Inverter Generator

On the other hand, an inverter generator has two parts of work, an inverter, and a generator. An inverter is also an electric device that is used to convert the direct current DC into alternative current AC. As DC is not suitable for every place we need AC power in our daily lives. But the thing is the only generator cannot produce AC power. To enable the system for households an inverter often incorporatesan extra electronic circuit, batter that can be charged, and load management. Based on a battery power system it acts as a power adaptor watchover the low and high power for the home appliances to save them from damage. The inverter produces and passes the same amount of power that the circuit of the appliance is able to take even if the main power load is high. The inverter can operate in two modes, stand-alone and connected mode to the main grid. This system is run for all of the household appliances like TV refrigerators, water purifiers, microwave ovens, and other low-power appliances.

Taking about the inverter generator they draw power from the DC sources to produce AC power directly, which is impossible via a regular generator. The converted electricity is produced in different voltages and frequencies. The specifications depend on the appliances that are going to use the converted electricity. Most of the inverter generators convert 12V DC power sources into 120V AC power sources.

In this section, we are going to talk about the difference between the inverter generator and the generator. The difference depends on some key factors, those are,

Size and weight

Comparing to the amount of power the inverter generator carries they are quite small in size. It is easy

to carry and store the inverter generator. Because of high portability, one can go hiking, camping with an inverter generator. It will fit well in the back storing area of the car.

However, generators are normally large and not portable. As well as the generator is normally so noisy, heavy, and bulky. So it’s not usual to carry a generator. Besides, a generator creates so much waste and dirt.

In this size and weight term inverter generator is the best choice to travel with.


The generator is aimed to create power in power loss and intends to keep the electric appliance running. With a fuel tank, the generator is heavy. On the other hand, an inverter generator is not heavy like the generator as it doesn’t need a big fuel tank. Limited fuel capacity means the device will run for a limited amount of time, the life run time will be shorter. But the inverter has the quality of the fuel efficiency. It burns the fuel pretty well and adjusts the power production according to the power the electric appliance needs. There is no waste of power and fuel.

But the generator will run for a long time compared to the inverter generator having a big fuel tank. However the generator is not efficient as the inverter generator, it creates waste.

Having a run time of approximately ten hours the inverter generator saves up to 45% fuel. The time is mostly enough for many users.

Noise Level

One of the main differences between an inverter generator and a generator is the noise level. Usually, the generator is very noisy, one can hear the sound of the generator from a well long-distance because it runs a speed of 3600rpm to produce electricity.

The inverter can adjust the amount of power producing level using a microprocessor. That means the device will regulate the output power depending on the required power. Because of this, the load will be less and it will create less noise.


The generator is such a device that can take a heavy load in a great capacity because of the big fuel tank. They are more suitable for a long power cut and many numbers of the electric device.

But the inverter is the moderate capacity device that is ideal to run the household appliances in the power loss. The inverter comes with auto shut off and shut on features that do not require manual operations like the generator.


The generator runs the engine at full speed to produce electricity so the load on the engine is high, the engine suffocates to keep producing the same amount of electricity. The ultimate output is directly connected to the load without processing.

In the case of the inverter generator, AC electricity is produced by converting the DC into AC. The capacitors of the DC smooth out the produced current to a certain degree before it is converted into AC.

The inverter produces consist amount of current and reliable power that is not dependent on the speed of the engine. That’s why the current is much cleaner than the power produced by the generator. Being the sensitive microprocessors in the home appliances it is important to use clean electricity to save the devices alive. If the devices use power that is not clean then they will end up malfunctioning and they can get damaged. Any kind of device that is sensitive should always use clean electricity.

Power sources

For a generator, the engine is the primary source of power, which is run on gasoline or propane fuel.

Usually, people use gasoline to run the generator which improves its portability.

On the other hand, the inverter generator converts the stored power into AC power. The inverter uses

solar panels or turbines as the main power source.


Generators are not very expensive, they are cheap and less costly to repair if they get damaged. The simple design and functionality make it easy, available, and fair price to buy its spare parts.

However, an inverter generator is more compact, quieter, and efficient with controlled output, which requires a complex mechanism so it’s expensive. But it necessary and the maintenance cost will not be much.

Maintenance Cost

The generator uses gasoline or propane fuel to run. That requires maintenance of oil change, daily cleaning, lubricant change, and so on. Gasoline has a lifeline of one to two years with decent maintenance costs.  However, the inverter generator doesn’t need much maintenance since it runs over the complex circuit.

What are the benefits of an inverter generator

The main benefit of the inverter generator is the less noise it made. Many of the peoples around the world are very sensitive to heavy noise and have sound disorder, some even get sick but that will not happen with the inverter generator. The inverter generator is designed from the ground to be much quieter and uses special sound demanding technology to reduce the noise level.

Another benefit of the inverter generator is it will adjust the production of power level according to the power the appliances need to run. That’s will waste less energy. The inverter can control the engine power and produce the required output that makes it efficient.

Will an inverter generator run a refrigerator

The inverter generator main aim is to convert the DC supply into a 120V AC supply to run the household appliances. As the refrigerator is a home appliance and hasa sensitive circuit that will not run well by the DC electricity supply. It will require clean power to run smoothly. The inverter generator produces clean energy that can run a refrigerator smoothly without harming the internal circuit.

Inverter Generator Vs Generator

What size generator will power a house

To run a household all the appliances with a generator, one will need a generator of 5000 watts to 7500 watts. That amount of powered generator can run all the appliances like light, pump, freezer, washing machine, and so on.

Final Words

There is some basic difference in mechanism working procedure between the generator and inverter generator. Both of them are technically different though they have the same purpose. Producing electricity when there is a load shedding or power loss. However, the generator only produces DC electricity and the inverter generator produces AC electricity. We cannot use DC electricity in the appliances which are made of the sensitive microprocessor. So one will need an inverter even if they do not want one.

The inverter generator has another big difference in a good way. Inverter generator can control the speed of its engine according to the power the device needs that make it more efficient and long-running. But the generator has no such ability, the generator will run at the maximum speed to continue producing the same amount of electricity even if that much is not required.

After reading this article one will know the required knowledge about inverter generator vs generator.
