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.
