The Uninterruptable Power Supply (UPS) and Inverter both provides the backup supply to the electrical system. One of the big difference between the UPS and inverter is that the switching of UPS from the main supply to the battery is very immediate whereas in inverter the switching from mains supply to battery takes times. The UPS and the Inverter are differentiated below in the comparison chart by considering the various other factors.

It should be noted, that some Inverters and UPS's can have multiple modes in order to satisfy the need for the specific application.

Uninterruptable Power Supply (UPS)

The abbreviation of the UPS is the Uninterruptable Power Supply. The UPS has a battery which supplies the power during the power outages. It provides the power for a short duration so that data can save before the complete shutdown of the system.

Inverter

The inverter inverts the direct current to an alternating current. It takes the supply from the AC source and charges the battery. During the power cut, the inverter receives the supply from the battery (DC) and provides the power supply to the electrical equipment (AC).

UPS INVERTER
Definition The UPS is an electrical device that provides power to the load when the main power fails. The inverter converts the unidirectional current into bidirectional.
