Patent ID: 7227278

Claim:
In a power sharing system in a DC load environment having: a source of AC; an alternative source of DC; a power controller capable of inputting voltage regulated DC power simultaneously from said sources, said alternative 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 a DC compatible load at an output of said power sharing system; said power controller controlling supply side power sharing 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 voltage regulated power by controlling response of said alternative source of DC power; said power controller directing power from secondary sources of DC power to limit peak power supplied from said source of AC power to said DC power to limit peak power supplied from said source AC power to said DC compatible load in accordance with a pre-set threshold of power from said source of AC power in order to minimize peak power surcharges; the improvement comprising: means for operating said alternative source of DC in a dynamic manner that allows the utilization of all the power generating capability at the specific operating conditions of the moment; and, means for delivering power from said alternative primary power source of DC in excess of that required by said DC compatible load back to said source of AC.
