1. A system for supplementing a generated renewable energy DC supply with a utility grid AC supply, comprising:

  • a generated DC;

    a DC to DC converter with pulse width modulation (PWM) control;

    a current sensor after the DC to DC converter;

    a micro controller that can control the PWM control of the DC power supply between zero and 100 percent;

    a DC load;

    an AC supply;

    an AC to DC converter with ON/OFF control for producing a line DC;

    a means for combining the line DC and the generated DC;

    wherein, when the PWM for the DC to DC converter is at 100%, the microcontroller can supplement power delivered to the DC load by increasing or decreasing the length of time that the AC to DC converter is ON.
