A UPS System can be stand-alone systems that work in conjunction with generators and back up critical systems. These are used primarily for server rooms, computer data systems, phones, telecom applications, and anything that deals with large quantities of data.

Primary Objective
Their primary objective is to prevent the loss of large amounts of critical data in case of a power outage. It fills the outage between street power and a generator. When there's a catastrophic power failure, it goes automatically to UPS and then onto battery. This is great because it provides huge savings, eliminating the need for recovery costs.
