Difference Between UPS & Inverter


Hello guys! Are you facing confusion between the UPS and inverter? Don’t worry much. You have landed on the correct article. Here side you will get the difference between the UPS and the inverter.

Do you know the major difference between the both of them? It comes in the battery switching with the main circuit. In UPS main supply to the battery from the circuit gets immediate. Meanwhile, the inverter takes time to get switching to the battery from mains.

UPS recognizes as an Uninterrupted Power Supply. It gets applied to power with the help of power outages. This device furnishes the power for a shorter time. Meanwhile, the system will store the data before it gets full power off.

The inverter has the main function of inverting the direct current into AC. The device takes supply from AC and gets down to charge the battery. Suppit’sit’s a power cut condition. In this case, the inverter will take supply from the battery and run the electrical equipment. Let’s have an overview of the difference between the UPS and inverter. 

Comparison between the UPS and inverter

  • Definition
UPS                              Inverter
It an electrical device that helps to load the power when the main circuit has faced cut-off. It can convert the unidirectional current into the bidirectional current. In short, it converts AC to DC lines.


  • Function
UPS Inverter
It works as per the flywheel storage system It mainly works to convert the AC into DC power.


  • Switch over
UPS Inverter
Immediate switch over occurs to main supply with help of UPS. The inverter takes some time to get switch over to the main circuit.


  • Backup
UPS Inverter
It delivers electricity when power cut-offs. it delivers the electronic power which got stored earlier.


  • Types
UPS Inverter
It has various type of UPS servers as follows:

1.      Offline

2.      Online

3.      Interruptive or standby UPS

Here are a few types of inverter available in the market as follows:

1.      Stand Alone

2.      Grid-tie inverter


  • Connection
UPS Inverter
UPS can have a direct connection to appliances. The inverter firstly gets connected to the battery and then to the appliances.


  • Cost
UPS Inverter
UPS is more expensive as compared to the inverter. Inverter gets lesser expensive as compared to UPS.


  • Circuit
UPS Inverter
It works on a circuit based on inverter and controller type. Its works only with a battery.


  • Supplying power
UPS Inverter
It supplies the power for a shorter duration. It delivers the power for a longer duration.


  • Voltage fluctuation
UPS Inverter
UPS doesn’t contain any voltage fluctuation. The inverter has voltage fluctuation. Due to this, it can convert AC into DC.


  • Use
UPS Inverter
It could have better use in industries and domestic areas also. The inverter can only prove effective in domestic areas.


Detailed explanation for the UPS and inverter  

What is UPS?

The UPS comes in the scenario to save the data whenever the power gets cut off. Also, it functions to protect the system from sudden high voltage. Are you still confused with its working?

UPS comes with a battery that has direct contact with appliances. It happens when it feels the power loss from the main circuit. The main circuit has a battery, inverter, and controller.

How does the UPS work? Firstly it converts the AC to DC power using the rectifier. Again the power gets converted from DC to AC using the inverter.

Mainly there are three types of UPS available in the market. You might have noted it down from the earlier part.

What is an inverter?

Inverter recognizes as an electrical device that modifies the DC to AC circuit. Inverter can’t generate electrical power. It delivers the power supply with the help of a battery.

The input of power in the inverter always gets with the DC. After this, output power might get transfused in a square, sine pulse, etc. It depends upon the design of the inverter.

The frequency of the output power in the inverter always remains the same and normal. It means it gets ranged from 50 to 60 Hz.

The runtime of the inverter gets with a longer duration. But then too, it depends upon the appliances connected. If there’s a connection with more appliances, the run time might get decreased. To overcome this scenario, people connected the inverter with more DC power.

The inverter works to supply the AC to the connected equipment when face power cutoff. The inverter can prove effective in controlling the speed of the motor.

The key difference between the UPS and inverter

  • The UPS is an electrical device that has a rectifier. It helps the system to get backup power. However, the inverter only converts DC into AC.
  • UPS can store the electric power for future use. But the inverter converts AC to DC power.
  • During the power cutoff, UPS immediately reacts to it and gives the power supply. In the case of the inverter, it will take some time to bring the power supply.
  • UPS proves effective in every area like industries, offices, homes, etc. But inverter can only prove useful in offices and home.


  1. Which type of current can inverter convert? 

Ans. The inverter can convert the DC into AC only. After this, it takes power from the battery and gives it appliances.

  1. Which is costlier among the UPS and inverter? 

Ans. UPS gets costlier as compared to the inverter. Its because UPS can store the electric current and gives an immediate reaction. Hence, in any condition, people having UPS will not face electricity problems.

  1. Is there any drawback of the UPS as compared to an inverter? 

Ans. Yes, there is a drawback for UPS. It delivers the power for only a short duration of time. But inverter can give you supply for a longer period.


Guys hope you have understood the difference between the UPS and inverter. Both of these works well. But depending upon your situation and essentials, you can choose one among them. Which will you choose, UPS or inverter? Please comment down and share your review.
