Theft detection and prevention in a power generation system
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.
1. A system comprising:
a central control unit;
a plurality of photovoltaic direct current (DC) power sources configured to generate DC power; and
one or more transmitters configured to transmit signals to one or more receivers, wherein the central control unit is configured to alert a potential theft of one or more of the plurality of photovoltaic DC power sources based on determining that a signal strength associated with a received signal is below a threshold signal strength.
2. The system of claim 1 , wherein the central control unit is operatively attached to the one or more transmitters via power line communication or a wireless connection.
3. The system of claim 1 , wherein the one or more receivers are affixed to one or more of the plurality of photovoltaic DC power sources.
4. The system of claim 1 , wherein the central control unit comprises an inverter configured to convert received DC power from the plurality of photovoltaic DC power sources to alternating current power.
5. The system of claim 1 , further comprising one or more transceivers comprising the one or more transmitters and one or more receivers.
6. The system of claim 1 , wherein the central control unit is operatively attached to the one or more transmitters and the one or more receivers via an inverter configured to convert received DC power from the plurality of photovoltaic DC power sources to alternating current power.
7. The system of claim 1 , wherein a receiver of the one or more receivers is configured to:
receive the signals transmitted from the one or more of transmitters;
measure a strength of each received signal; and
determine the strength of each received signal, relative to the threshold signal strength.
8. The system of claim 7 , wherein a transmitter of the one or more transmitters, corresponding to the receiver, is configured to transmit a change in the strength of each received signal to the central control unit.
9. The system of claim 1 , wherein the one or more transmitters are affixed to one or more of the plurality of photovoltaic DC power sources.
10. The system of claim 1 , wherein the central control unit is operatively attached to the one or more receivers via power line communication or a wireless connection.
11. The system of claim 1 , further comprising:
a thermal imaging camera configured to capture images of a plurality of solar panels associated with the plurality of photovoltaic DC power sources, wherein the central control unit is configured to:
reverse bias, based on the determining, the plurality of solar panels;
cause the thermal imaging camera to capture the images of the plurality of solar panels after the reverse bias; and
alert, based on analysis of the captured images, the potential theft.
