When using inverters or generators for our homes and offices, many confuse the right ones to pick for maximum usage.

Although there is a difference between an inverter and a generator, most people don’t fully understand it and believe both to be the same. 

Electricity plays a significant role in our everyday life, and without the power of electricity, we can’t begin to imagine how our lives would be.

Hence, if the power supply goes off and all the electrical devices ate switched off, the need for a backup power plan to continue the work without distraction can not be overemphasized.

Thus even with the difference between an inverter and a generator, they play essential roles as backup plans.

Generators produce electrical power while inverters convert direct current to alternating current. Both can be used in commercial and home applications, but deciding on the particular one depends on various factors.

Your generator can help you power many appliances or devices when there is no source of electricity or power outage.

There are different types of generators, and having the right one can be a relief when needed. When preparing for the unknown or wanting to have a backup plan or you want to have the electricity backup plan set up, choosing the right generator for unforeseen circumstances is a must.

 The difference between an inverter and a generator is briefly discussed on the foundation of factors like the voltage, their time of starting, noise, source of power, ways of installation, time of power outage, fuel storage, weight, and size of the machines, space requirement, operation, and cost.


A generator is an electrical device that turns mechanical energy from an external force into electricity for use in an external circuit. When there is no power supply, it provides electricity to homes, industries, and offices.

The Designs function associated with a generator depends on the type of energy produced, the size of the generator, and the location where it is needed.

They use coal, natural gas, and oil as a source of power supply hence bringing us to the disadvantages of using a generator

They are challenging to maintain and also cause noise and air pollution. Storing and refilling fuel is inconvenient, and it also causes fire hazards and also not compatible or suitable for solar panels. And the advantages are

There is always an electricity supply, and relying on a generator backup, allows you to forget about time and productivity losses during power blackouts. 

  • It also allows you more mobility, and your project is always in charge.
  • It contributes to sustainability and is also an investment that pays off.
  • Saves in consumption and more efficient energy production.


An inverter is an electronic device that changes electrical energy to an alternating current. The subsequent frequency acquired depends on the exact device used.

In our daily use of electrical appliances and gadgets, the importance of an inverter cannot be over-emphasized. If your home or office is not equipped with an inverter, such a situation can leave you helpless when the power goes off.

Essential work of an inverter

The primary work of an inverter is that it transforms the direct current into alternating current; subsequently, every home has a different necessity, which is why there is a wide variety to select from.

Inverters are made for the users’ comfort, and the uses of inverters are as follows. An inverter is very safe for electronic devices such as computers and printers, creating a pure sine wave that fits the quality of the main supply.

  • It provides an uninterrupted power supply with no starting time and doesn’t create any inconvenience.
  • It causes no pollution, and it hardly makes any noise. also, it has greater productivity and lower running cost
  • Inverters are designated for solar compatibility. Hence, it can generate electricity using solar power or even charge batteries.

Difference Between an Inverter and a Generator

The difference between an inverter and a generator explains that. 

  1. The generator directly manufactures 120 volts Ac supply, and an inverter converts or transforms 120-volt dc into 120 ac power.
  2. Generators take a considerable amount of time to start when there is a power blackout while inverters restore the power supply, and it doesn’t delay to start of the collection of power. 
  3. Generators are generally fond of making loud noises when activated, which brings out smoke causing air pollution, while inverters are noiseless and do not bring out smoke.
  4. Generators need power sources like kerosene, diesel, natural gases, or petroleum to be fully active, while an inverter operates with a battery and it charges its battery itself.
  5. The generator from the startup is already coupled or established, while inverters need installation and a wiring system.
  6. Generators demand manual startup, while inverters start on their own as long as there is a power cut.
  7. Generators are accessible in high capacities, while inverters are in low power.
  8. Generators are used where there are prolonged power outage problems, while inverters are suitable where there is a short power outage.
  9. Maintainance of the generators battery is a necessity from time to time, while the inverter requires no maintenance at all.  
  10. There is a need for fuel storage when using a generator, while an inverter does not require fuel storage. 
  11. Using a generator requires a large amount of space as it is often kept outside the office or at home, while the inverter requires little or less space and is kept inside the house. 
  12. The generators are large in size and shape and often very heavy compared to a very light inverter, and inverters are very costly compared to generators.

With this difference between an inverter and a generator, it is evident that they are not the same even though they serve the same purpose, producing light in times of blackout.

Inverter or Generator, Which is Good for Home Use or Application?

with the difference between an inverter and a generator, it is left for the user to make a suitable choice for the one that best fits the home

Generators at a wide range can produce more power. They are used for heavy power appliances like the refrigerator and Ac, and their power backup can last for as long as you want on the condition that you keep feeding them fuel.

However, they are bulky in design, occupy more space, and are placed in discrete locations to avoid fire hazards.

And on the other hand, inverters are compressed, very easy to run, and very quiet, making it favorable for home users, and majorly, they don’t need manual power-up.

They are available in different patterns to fit the house’s interior but can not sustain the load of heavy appliances or devices. For such reasons, a higher inverter will be needed costing more.


Although inverters and generators are the two most essential terminologies employed in the power organization to reduce energy reform, they vary significantly in their functions and magnitude.
