Abstract:
1. A photovoltaic system comprising, a first and second inputs adapted to couple to a first and second rails of a first photovoltaic array; a power converter, the power converter coupled to a first rail of a second photovoltaic array and a second rail of a third photovoltaic array; an interface portion coupled to (i) the first and second inputs, (ii) a second rail of the second photovoltaic array, and (iii) a first rail of the third photovoltaic array, the interface portion configured to isolate the first photovoltaic array from the second and third photovoltaic arrays and to modulate an application of a voltage from the first photovoltaic array to the second and third photovoltaic arrays so as to adjust a voltage applied from the three photovoltaic arrays to the power converter.
