Abstract

An energy storage system including a first power conversion device and a second power conversion device for providing energy to loads upon interruption of a main power source. A first power conversion device is connected in parallel to a first load, receives energy from an energy storage device and provides power to the first load. A second power conversion device is connected in series with a second load, receives energy from the energy storage device and provides power to the second load. The first and second power conversion devices are rated so that power consumption by the power conversion devices is reduced.
