1. A power sharing system in a DC load environment comprising:

  • a primary source of AC;

    an alternative primary 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 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 controlling response of said alternative primary source of DC power; and

    ,said power controller capable of altering the input voltages of said power junction means for directing power from said alternate primary source 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.
