1. An electric power conservation system for use between a primary power source and a load circuit, comprising:

  • a) a bypass isolation means operable between a bypass current path and an energy conservation current path, for activating and deactivating the bypass current path and the energy conservation current path;

    b) a first contact means operable between open and closed conditions for providing an energizing current path for a first actuating means;

    c) a second contact means operable between open and closed conditions for coupling bypass current from a primary power source to a load circuit;

    d) the first actuating means, that actuates the second contact means, the first actuating means being connected between the primary power source and the first contact means;

    e) a monitor and control means for responding to system conditions and load circuit requirements, and for producing stimulus signals to energize system circuitry, so as to minimize the power supplied by the primary power source;

    f) a third contact means operable between open and closed conditions to provide an energizing current path for a second actuating means, the third contact means being connected between the second actuating means and the monitor and control means;

    g) the second actuating means, that actuates the third contact means, the second actuating means being connected between the third contact means and a return connection of the primary power source;

    h) an energy charger component for supplying sufficient charge to a direct current rechargeable energy source, the energy charger component being connected between the bypass isolation circuit and the direct current rechargeable energy source, and deriving power from the primary power source;

    i) the direct current rechargeable energy source for supplying power to an inverter unit, the direct current rechargeable energy source connected between the energy charger component and the inverter unit, and the direct current rechargeable energy source providing power for the inverter unit and the monitor and control means;

    j) the inverter unit, that supplies required power to the load circuit, the inverter unit being connected between the direct current rechargeable energy source and the bypass isolation means;

    k) a fourth contact means operable between open and closed conditions for providing an energizing current path for a third actuating means, the fourth contact means connected between a second connection point and a primary power return;

    l) a fifth contact means operable between open and closed conditions for coupling the primary power source to the energy charger component, the fifth contact means being connected between the primary power source and the energy charger component;

    m) the third actuating means, that actuates the fifth contact means, the third actuating means being connected between the primary power source and a manual bypass means;

    n) a sixth contact means operable between open and closed conditions for coupling the inverter unit to the load circuit;

    o) a fourth actuating means for actuating the sixth contact means, the fourth actuating means being connected between the monitor and control means and the primary power return;

    p) an arc suppressing means for suppressing any arcing that occurs when the contacts are manually switched between operating modes; and

    p) a break-before-make means for insuring that separate current paths remain isolated during switching between operating modes.
