Patent ID: 6933627

Claim:
A power sharing system in a DC load environment comprising: a primary source of AC; an alternative primary source of DC; a secondary source of DC; a power controller capable of inputting voltage regulated DC power simultaneously from said primary sources, said alternative primary source of DC making a shared contribution of power selected by said power controller, and having a power junction means for delivering a regulated voltage DC to at least one DC compatible load at an output of said power sharing system; said power controller controlling supply side power sharing at to a DC load side; said power controller having a converter converting AC inputted electrical power into a defined DC-regulated voltage to provide and manage power to said DC compatible load; said power controller producing outputting voltage regulated power controlling response of said alternative primary source of DC power; said secondary source of DC being a storage battery to supply power in the event of a failure in a primary source of power, said power controller charging and maintaining said battery in a state of charge, and, said power controller capable of altering the output voltage of said power junction means for directing power from said secondary sources of DC power to limit peak power supplied from said primary source of AC power to said at least one DC compatible load in accordance with a pre-set threshold of power from said primary source of AC power in order to minimize peak power surcharges.
