Theft detection and prevention in a power generation system
First Claim
1. A method, comprising:
- receiving a first impedance value associated with at least one direct current (DC) power source and measured based on a first signal applied to a DC power line of the at least one DC power source;
storing the first impedance value;
receiving a second impedance value associated with the at least one DC power source and measured based on a second signal applied to the DC power line of the at least one DC power source;
comparing the stored first impedance value to the second impedance value; and
determining whether to transmit an alert based on the comparing.

Abstract
A system for generation of electrical power including an inverter connected to a photovoltaic source including a theft prevention and detection feature. A first memory is permanently attached to the photovoltaic source. The first memory is configured to store a first code. A second memory is attached to the inverter. The second memory configured to store a second code. During manufacture or installation of the system, the first code is stored in the first memory attached to the photovoltaic source. The second code based on the first code is stored in the second memory. Prior to operation of the inverter, the first code is compared to the second code and based on the comparison; the generation of the electrical power is enabled or disabled.
