How is an Inverter Different from a UPS System?

Inverters and UPS systems both are the backup solutions that supplies power in the event of main power failure. Even as both the equipments feed backup power during mains failure, the time lag is the only difference. A UPS starts supply right away, while in case of an inverter, there is about a moment’s delay or even less which matters a lot if the device that you need to power is a computer. For the other appliances, this time lag goes unnoticed and this is why UPS is mainly used for computers, while an inverter supplied by many inverters manufacturer India is used for all other domestic appliances.  

AC power is converted to DC power in an Inverter which is later on used for charging the battery. When the power cuts off, the relay switches off the power from mains to inverter. The time delay in the power supply is also the result of the use of relay and sensor. UPS receives the main power that is used to charge the battery that is fitted inside it. The battery supplies output to a sine wave inverter that transforms DC into AC and supplies to the computer when the power goes off.

The circuitry that is incorporated in digital home UPS is expensive in comparison to inverter; this is the reason UPS is more expensive. As a result, UPS with an additional advantage of lesser time lag is appropriate for devices like computer, which may break down while it tries to connect to the inverter when the mains supply is cut off. Moreover, UPS is also devoid of voltage fluctuations whereas it is a problem is case of inverter as its voltage is reliant upon the input voltage.
