Difference between ups and inverter

Today we all know that electricity has become a necessity. All most all of our work requires electricity. We need electricity for laptops, electric cookers, mobile, computer, coolers, phones, etc. The main difference between the UPS power supply provides power supply even there is a power cut. UPS mostly used for desktop computer backup while the inverter is a power back up solution. It converts DC  current to AC and supply. Here this post gives information about the difference between UPS and inverter to better understand this topic.


The main key difference between UPS and Inverter are given below.
  • UPS is the electric device which has rectifier for providing the backup power to the system whereas the inverter converts the AC into DC. So the UPS provides the electrical backup power, and inverter provides the electronics backup power supply.
  • The main function of the UPS is to store the electric supply while the inverter converts the AC power into DC power.
  • The UPS is more expensive as compared to the inverter device.
  • During the power outages, the UPS immediately switch over from the mains supply to the battery whereas the inverter has a time delay.
  • The UPS is directly connected to the home appliances whereas the inverter is first linked to battery and then attached to the appliances circuits.
  • The online, offline and line interruptive are the types of UPS but the inverter is of two types.
  • UPS, Inverter both not create noise.
  • UPS does not have voltage fluctuations compared to the inverter.
  • The UPS provides the backup supply for a very short duration while inverter supplies the power for an extended period.
  • The UPS does not have voltage fluctuation because their input is independent of the output supply while the inverter has too much voltage variation.
  • The UPS is used for domestic purpose like offices, industries whereas the inverter is used in the office.
  • The rectifier and battery are inbuilt in the circuit of UPS while inverter has an external battery for storing the DC power.
