1. A power conditioning unit for delivering power from a DC power source to an AC circuit, the power conditioning unit comprising:

  • a DC input for receiving power from the DC power source;

    an AC output for delivering AC power to the AC circuit;

    a non-electrolytic energy storage capacitor configured to store energy from the DC power source for delivery to the AC circuit, wherein a peak amplitude of a fluctuating DC voltage on the energy storage capacitor depends on an amount of power transferred from the DC power source to the AC circuit;

    a DC to DC converter having an input connection coupled to the DC input and an output connection coupled to the energy storage capacitor; and

    a DC to AC converter having an input connection coupled to the energy storage capacitor and an output connection coupled to the AC output.
