What is Inverter Technology in Refrigerators?- How it Works, it’s Benefits and More!

You are out at the electronics store trying to find the best fridge for your kitchen, but the salesman keeps going on and on about inverter and non-inverter fridges, and it is making you even more confused.

If you are currently asking yourself questions like- what exactly is inverter technology?, What are its advantages? and will it be the best choice for my family? worry not because we have answers to help you! Read on to know more and make an informed decision.


What is a Compressor?

What Is a Compressor

Have you ever wondered how does a fridge keep your food cold? It does because it has a compressor.

Compressors are a component present in your fridge that works to compress and control the flow of the refrigerant. In basic words, it is the part of the fridge that pumps in cool air to keep your food fresh for a long time. 

Normal compressors work on two settings: either on or off.

When you set your non-inverter fridge at a temperature, the compressor will turn on and work at its full capacity to get the fridge’s temperature to your desired level; after that, it will shut off. when the thermostat notices a fluctuation in the temperature the compressor will turn on again to reset the temperature of the fridge. This process goes on all day.

Regular Compressors have to start and stop many times during the day; hence they consume a lot of energy and are noisy. 


What are Inverter Compressors?

Inverter Compressors

Inverter Compressors are a new breed of compressors fitted with an inverter. What are inverters?- inverters are devices that can control the incoming electrical current’s frequency, allowing the compressor to work at variable speeds.

 What makes an inverter compressor special? – A normal compressor, as mentioned above, has to turn on and off many times in a day to maintain the desired temperature, but that’s not the case for an inverter compressor. 

When you set a temperature in your inverter fridge, it will turn on to reach the desired temperature, and after it’s done, it won’t stop; instead, it will start working on lower energy to maintain the temperature. When it notices a high-temperature fluctuation, it will again go into a higher power mode to return to the set temperature.


Inverter Vs Non-Inverter refrigerator 

Inverter technology is a comparatively newer technology that has been introduced in refrigerators. It has brought about a lot of changes in how a fridge works. 

The below-mentioned table gives the main difference between an inverter-operated fridge and a regular fridge. A detailed explanation has been in the following section to help you understand it better.

Inverter Refrigerator 

Non-inverter refrigerator 

Efficient usage of energy Inefficient usage of energy
Less noisy  Noisy 
Better temperature control Low-temperature control
Lasts for long Low life span 
Foods stay fresh longer Foods go bad quicker 
Expensive  Affordable
Slower cooling performance  Fast cooling 


What are the Advantages of an Inverter Fridge?

What Are The Advantages Of An Inverter Fridge

Due to its ability to control its speed and work according to the needs of the fridge, the inverter refrigerators have a lot of advantages over a normal refrigerator: below are some-

1. Efficient Usage Of Energy

Restarting, again and again, causes a lot of energy usage in a normal compressor, but the inverter compressor does not do that; hence it is energy efficient.

The speed of an inverter compressor is controlled closely, which helps it save about 40% more energy than a normal fridge of the same size; this will result in shorter electricity bills!


2. Less Noisy

Inverter fridges are less noisy as compared to normal fridges. 

Normal compressors, while turning on, emit a loud whirring sound. As they have to keep turning on and off to maintain the temperature, it can be irritating to hear your fridge start roaring out of nowhere then turning silent and roaring again, but this is not the case for an inverter fridge.

The inverter fridge will emit a noise when the compressor turns on; after that, It will go into a low power mode, and you will most probably hear a low humming noise.


3. Temperature Control

Fridges with normal compressors have very low control over the temperature. They can run only at a fixed speed, but Inverter compressors can work at variable speeds and maintain the fridge’s temperature according to the cooling demand; hence they have better temperature control than non-inverter Fridges.


4. More Lifespan 

Non-inverter compressors experience heavy stress when they have to turn on. The constant turning on and off drastically reduces their lifespan.

On the other hand, inverter compressors don’t have to work that hard as they maintain variable speeds; they work smart and hence are durable and stay working for long!

This you can also see in how manufacturers give out warranty for both the types of the fridge- Non-inverter refrigerators will mostly have a warranty of upto five years while their inverter counterparts can be promised upto ten years!


5. Compatible with Home inverters

Inverter refrigerators consume low energy; hence you can easily run them on home inverts or solar PVs; this is not possible with a normal non-inverter refrigerator. 


6. Foods Stay Fresh For Long 

An inverter compressor can work according to your needs and go fast or slow. With an inverter compressor-operated refrigerator, you can maintain the correct temperature required for the foods stored inside and help keep them fresh for a long time! You cannot do this in a regular refrigerator.


What are the Disadvantages of an Inverter Fridge?
What Are The disadvantages Of An Inverter Fridge

Though the inverter fridge is better than a normal one in many aspects, it still has some disadvantages as compared to normal refrigerators; they are- 

1. More Expensive

Inverter technology in refrigerators is comparatively new and comes with many new features; hence it is very popular currently, causing it be priced more than a normal fridge and hence can be expensive.


2. Slower Cooling Performance

Normal refrigerators, while turning on, consume a lot of power and hence end up cooling the fridge fast, but inverter compressor operated fridge take time to reach the desired levels. This makes them slower as compared to normal refrigerators.

The advantages of an inverter fridge greatly outweigh its disadvantages; though it is costly, in the long run, it can prove to be cheaper as it is energy efficient and will help you reduce your electricity bill as compared to when using a regular fridge. So when making a decision, it will be good to go for an inverter-operated fridge. 



1. What is the difference between a 5-star refrigerator and an inverter refrigerator?

The five stars is a rating, while the inverter refrigerator is a technology. The rating on your fridge tells you how much electricity the fridge will consume; hence it denotes the fridge’s efficiency. A five-star rating means that the refrigerator is very energy efficient. Inverter refrigerators are presented with a five-star rating as they are energy efficient.


2. What is the difference between a digital inverter and a smart inverter? 

Both digital and smart inverters are somewhat similar in their workings and can adjust their cooling as per requirements, but a smart inverter is more efficient in its work and can change adjust its cooling according to the food present inside the fridge.

Inverter technology is an innovation in how we store our food and is helping make high performance on low energy possible! Inverter fridges are more durable, less noisy, and keep foods fresh for long as compared to their non-inverter counterparts, but they are also comparatively more expensive and slower, but looking at its advantages, its disadvantages will seem less. After reading this article, you can now make an informed decision and buy the best fridge for your family.
