Inverter and UPS provides Power When there is a power failure, in this case electricity supply to the appliances in use is cut off and they stop working. To fix these issues of power outages and unavailability of electricity, the UPS and the inverter were devised. An inverter and a UPS are both used in providing back-up power supply to electronic devices, in the event of an electricity outage.

Their basic function is the same in that they store electricity in a battery when power is available, and provide it to various devices in the event of an electricity outage. However, they both are different in their circuitry, price, functions, etc. All UPS contain an inverter as well as a battery charger, but not all inverters offer a built-in battery charger, which would then need to be purchased separately.
