UPS = Uninterrupted Power Supply

Protects your PC from Power fluctuations and prevents system crash if there is a sudden power failure. Has a small battery backup which provides enough time to systematically shut down the PC. The battery can be upgraded to last longer.

Inverter = It consists of a battery which gets charged when the Main supply is on. When there is a power failure and mains are cut-off, it discharges supplying power to the household. The battery capacity is far greater than that of a UPS.
