Abstract

The present invention is directed to monitoring or control of power production. A power production monitoring system may include a power production monitoring panel that is also configured to operate a premises control system. The power production monitoring system may include a gateway unit that receives signals from a power production source and sends signals to a power production monitoring panel.

Claims

1. A premises control system, comprising:

a power production source being coupled to one or more inverters, wherein the power production source is configured to supply power to a plurality of appliances associated with an electrical system on the premises;

a gateway unit in communication with the power production source and configured to obtain information regarding power production by the power production source;

a control unit coupled to the premises control system, the gateway unit, and the plurality of appliances, the control unit being configured to display a status of the premises control system and the information regarding power production by the power production source;

wherein the gateway unit is configured to transmit a troubleshooting signal to the control unit that is useful for indicating whether a portion of the power production source is under-producing such that a respective energy usage of one or more of the plurality of appliances is greater than the power production by the power production source;

a home electrical system coupled to the control unit and a utility grid, the home electrical system being configured to transmit power supplied from the utility grid, to the plurality of appliances, based at least in part on the indication that the portion of the power production source is under-producing, and

wherein the control unit is configured to;

determine that a threshold power has been supplied from the utility grid; and

adjust the respective energy usage of each of one or more of the plurality of appliances to maintain energy usage at the power production, based at least in part on the determination that the threshold power has been supplied from the utility grid.

2. The premises control system of claim 1, the control unit comprising a communication interface, the communication interface including a display device, a speaker, and a microphone.

3. The premises control system of claim 1, wherein the control unit is wirelessly coupled to the premises control system and the gateway unit.

4. The premises control system of claim 1, wherein the troubleshooting signal production signal is a production signal.

5. The premises control system of claim 1, wherein the gateway unit receives a production signal from more than one inverter and compares the production signal received from a first inverter to the production signal received from a second inverter to generate the troubleshooting signal.

6. The premises control system of claim 1, wherein the control unit is configured to display one or more of a current amount of power produced by the power production source, a historical amount of power produced by the power production source, a projected amount of power estimated for future production by the power production source, a cost of the power produced by the power production source, an amount of power used from the power produced by the power production source, an amount of power supplied from or supplied to the utility grid, or a comparison of power produced by the power production source to power produced in a different location or time period.

7. The premises control system of claim 1, wherein the control unit is configured to simultaneously display the status of the premises control system and the information regarding power production by the power production source.

8. A premises control system control unit, comprising:

a housing;

a display disposed within the housing and viewable from without the housing;

a processor disposed within the housing; and

a memory module disposed within the housing;

wherein the premises control system control unit is in communication with one or more appliances associated with the premises and a power production source;

wherein a gateway unit is configured to transmit a troubleshooting signal to the premises control system control unit that is useful for indicating whether a portion of the power production source is under-producing such that a respective energy usage of one or more of the plurality of appliances is greater than the power production by the power production source;

a home electrical system coupled to the control unit and a utility grid, the home electrical system being configured to transmit power supplied from the utility grid, to the plurality of appliances, based at least in part on the indication that the portion of the power production source is under-producing, and

wherein the control unit is configured to;

determine that a threshold power has been supplied from the utility grid; and

adjust the respective energy usage of each of one or more of the plurality of appliances to maintain energy usage at the power production, based at least in part on the determination that the threshold power has been supplied from the utility grid.

9. The premises control system control unit of claim 8, wherein the premises control system control unit is configured to accept input from a user and respond to the input.

10. The premises control system control unit of claim 9, wherein the input from the user is a command to select among various information to be displayed regarding the power production source or to selectively control the power production source.

11. The premises control system control unit of claim 10, wherein the premises control system control unit is configured to obey the command.

12. The premises control system control unit of claim 8, further comprising a keypad to accept input from a user.

13. The premises control system control unit of claim 12, wherein the keypad is a touch screen accessible through the display of the premises control system control unit.

14. The premises control system control unit of claim 9, further comprising a microphone, and wherein the premises control system control unit is configured to identify a desired result of a user'"'"'s voice commands detected by the microphone.

15. A method of monitoring solar power production on a residential lot, comprising:

retrieving information from a power production source located on the residential lot;

retrieving information from a peripheral device located on the residential lot;

displaying information relating to the power production source and/or the peripheral device indicating whether a portion of the power production source is under-producing such that a respective energy usage of one or more of a plurality of appliances is greater than a power production by the power production source;

transmitting power supplied from a utility grid, to the plurality of appliances, based at least in part on the indication that the portion of the power production source is under-producing;

determining that a threshold power has been supplied from the utility grid; and

adjusting the respective energy usage of each of one or more of the plurality of appliances associated with the residential lot to maintain energy usage at the power production, based at least in part on the determination that the threshold power has been supplied from the utility grid.

16. The method of claim 15, wherein retrieving the information from the power production source includes receiving a first signal from a first inverter and retrieving information from the peripheral device includes receiving a second signal from a second inverter.

17. The method of claim 16, further comprising comparing the first signal with the second signal to form a troubleshooting signal.

18. The method of claim 15, further comprising accepting input from a user and responding to the input.

19. The method of claim 18, further comprising selecting among various information to be displayed regarding the power production source or to selectively control the power production source.

20. The method of claim 16, further comprising displaying information comprises displaying one or more of a current amount of power produced by the power production source, a historical amount of power produced by the power production source, a projected amount of power estimated for future production by the power production source, a cost of the power produced by the power production source, an amount of power used from the power produced by the power production source, an amount of power supplied from or supplied to the utility grid, or a comparison of power produced by the power production source to power produced in a different location or time period.
