The difference between UPS and inverters

While both UPS and inverters provide backup power, inverters are preferred for general electric appliances whose working may not get affected by extended delays in power supply. The UPS is used for electronic appliances such as computers, servers, workstations and medical equipment which perform critical tasks and cannot tolerate delays in power supply. In UPS the switchover to backup power is prompt, while in an inverter there is a little delay. The UPS also provides protection to the load against spike, voltage fluctuation and noise.
