Abstract: A method and apparatus for converting DC power to AC power. For example, apparatus for converting DC power to AC power comprises an input adapted to be coupled to a high-powered distributed generator having a maximum voltage at a first voltage and an arc fault mitigation device, coupled to the input, for providing a second voltage at the input that is lower than the first voltage, where a difference between the first voltage and the second voltage is not large enough to cause an arc.

Abstract: A method and apparatus for autonomous rapid shut-down of a power conditioner. In one embodiment, the method comprises determining an amount of active and reactive current generated by a power conditioner; determining whether the amount of active and reactive current satisfies an open circuit threshold; and initiating, when the amount of active and reactive current satisfies the open circuit threshold, deactivation of the power conditioner.

Abstract: Method and apparatus for controlling power conditioners in a distributed resource island. In one embodiment, the method comprises comparing, at a power conditioner operating in a de-energized state, an input of the power conditioner to an input threshold, wherein the power conditioner is coupled to an islanded grid; operating the power conditioner, when the input exceeds the input threshold, in a soft-grid mode to generate a touch-safe AC voltage that is coupled to the islanded grid; comparing, by the power conditioner, an impedance of the islanded grid to a grid impedance range; comparing, by the power conditioner, load demand of the power conditioner to an activate threshold; and activating the power conditioner, when the impedance is within the grid impedance range and the load demand exceeds the activate threshold, to operate proximate its nominal output voltage.
