Abstract:
1. A method for directing power from alternative power sources to an electrical grid, the method comprising: receiving at least two input DC power signals from a plurality of power sources; receiving one or more control signals from the electrical grid; selectively directing a portion of the input DC power signals to a rechargeable battery; sensing available power from the at least two input DC power signals; selectively switching to couple with an output DC power signal, one or more of the at least two input DC power signals, based on the sensing of available power and the one or more control signals from the electrical grid; directing, based at least in part on the one or more control signals, at least some of the input DC power signals to an output DC power signal; and, transforming the output DC power signal to an output AC power signal for transmission via the electrical grid.
