  • Photovoltaic power system
    Patent number: 8344549
    Abstract: A photovoltaic power system includes module strings each having photovoltaic modules connected in series. The power system further includes a generator terminal box having DC converters. The power system further includes a generator main connection line and an AC inverter. Each module string is electrically connected to a respective one of the DC converters for the module string to provide a DC voltage generated by the photovoltaic modules of the module string to the respective DC converter. The DC converters output a combined DC voltage based on the DC voltages from the module strings to the AC inverter via the generator main connection line for the AC inverter to transform the combined DC voltage into an AC voltage. The generator terminal box and the AC converter are spatially separate from one another.
