Abstract: A method for theft detection in a system for generation of electrical power, the system including a DC power line. An alternating current (AC) is applied to the DC power line from an alternating current (AC) source and an impedance component of the system is sensed. The impedance is responsive to the applied alternating current (AC). An impedance datum proportional to the impedance is stored with the impedance datum transmitted to a receiver. Electrical charge may be stored to power the sensing when the system is not generating electrical power. The sensing includes measuring voltage and current of the alternating current (AC) source. A potential theft of a component of the system is alerted which is responsive to a change in the impedance greater than a previously determined threshold or upon not receiving an expected transmission of the impedance datum.
