A method of highly efficiently delivering solar energy power comprising the steps of: - accepting a first power from a first photovoltaic source of power by a DC input port of a base phase photovoltaic DC-DC converter; - base phase DC-DC converting said first power by utilizing a first tapped magnetically coupled inductor with a first inductor tap to output a base phase DC power delivery connected to said first inductor tap wherein both inputs of said first tapped magnetically coupled inductor are connected to both respective midpoints of said base phase photovoltaic DC-DC converter; - accepting a second power from a second photovoltaic source of power by a DC input port of an altered phase photovoltaic DC-DC converter; - altered phase DC-DC converting said second power by utilizing a second tapped magnetically coupled inductor with a second inductor tap to output an altered phase DC power delivery connected to said second inductor tap, wherein both inputs of said second tapped magnetically coupled inductor are connected to both respective midpoints of said altered phase photovoltaic DC-DC converter; - synchronous phase controlling said step of base phase DC-DC converting said first power with said step of altered phase DC-DC converting said second power; - low storage inductance series power combining said base phase DC power delivery with said altered phase DC power delivery through additive voltage circuitry that includes a low inductance storage series combination inductor connected between said first and second inductor taps to add an output voltage of said base phase DC power delivery to an output voltage of said altered phase DC power delivery with a low energy storage output capacitor to provide a conversion combined photovoltaic DC output at a maximum power point; and - photovoltaic boundary output controlling said step of base phase DC-DC converting said first power and said step of altered phase DC-DC converting said second power for a maximum voltage that overrides said maximum power point or for a maximum current that overrides said maximum power point at at least some times of operation. - accepting a first power from a first photovoltaic source of power by a DC input port of a base phase photovoltaic DC-DC converter; - base phase DC-DC converting said first power by utilizing a first tapped magnetically coupled inductor with a first inductor tap to output a base phase DC power delivery connected to said first inductor tap wherein both inputs of said first tapped magnetically coupled inductor are connected to both respective midpoints of said base phase photovoltaic DC-DC converter; - accepting a second power from a second photovoltaic source of power by a DC input port of an altered phase photovoltaic DC-DC converter; - altered phase DC-DC converting said second power by utilizing a second tapped magnetically coupled inductor with a second inductor tap to output an altered phase DC power delivery connected to said second inductor tap, wherein both inputs of said second tapped magnetically coupled inductor are connected to both respective midpoints of said altered phase photovoltaic DC-DC converter; - synchronous phase controlling said step of base phase DC-DC converting said first power with said step of altered phase DC-DC converting said second power; - low storage inductance series power combining said base phase DC power delivery with said altered phase DC power delivery through additive voltage circuitry that includes a low inductance storage series combination inductor connected between said first and second inductor taps to add an output voltage of said base phase DC power delivery to an output voltage of said altered phase DC power delivery with a low energy storage output capacitor to provide a conversion combined photovoltaic DC output at a maximum power point; and - photovoltaic boundary output controlling said step of base phase DC-DC converting said first power and said step of altered phase DC-DC converting said second power for a maximum voltage that overrides said maximum power point or for a maximum current that overrides said maximum power point at at least some times of operation.
