Distributed inverter and intelligent gateway
A system and apparatus for use in energy conversion. In one embodiment, the apparatus comprises at least one power converter for producing power at a first level while receiving an indicium of proper operation and, upon not receiving the indicium of proper operation, producing power at a second level, where the second level is less than the first level.
1. At least one power converter for producing power while receiving an indication of proper operation and, upon not receiving the indication of proper operation, not producing power,
wherein the indication of proper operation is generated by a gateway while the gateway is connected to the at least one power converter that is connected to a grid and enabled for converting DC power to AC power and transmitting the AC power to the grid, and
wherein the indication of proper operation is discontinued upon detection of at least one of: unsafe conditions, maintenance is to be performed, power converter upgrade, or safety hazard.
2. The at least one power converter of claim 1 comprises at least one of a microinverter, an inverter, a distributed inverter or a string inverter.
3. The at least one power converter of claim 1 wherein the indication comprises a communication signal.
4. The at least one power converter of claim 3 wherein the communication signal comprises a pulse signal.
5. The at least one power converter of claim 1 wherein the indication is delivered to the at least one power converter via wire, wireless or power line communications.
6. The at least one power converter of claim 1 wherein the indication of proper operation is discontinued upon further detection of at least one of: a fault, or an AC power failure.
7. A power converter for producing power while receiving a pulse signal and, upon not receiving the pulse signal, not producing power,
wherein the pulse signal is generated by a gateway while the gateway is connected to the at least one power converter that is connected to a grid and enabled for converting DC power to AC power and transmitting the AC power to the grid, and
wherein the pulse signal is discontinued upon detection of at least one of: unsafe conditions, maintenance is to be performed, power converter upgrade, or safety hazard.
8. The power converter of claim 7 comprises at least one of a microinverter, an inverter, a distributed inverter or a string inverter.
9. The power converter of claim 7 wherein the pulse signal is part of a communication signal.
10. The power converter of claim 7 wherein the pulse signal is delivered to the power converter via wire, wireless or power line communications.
11. The power converter of claim 7 wherein the pulse signal is discontinued upon further detection of at least one of: a fault, or an AC power failure.
12. A power generation system comprising:
a gateway for transmitting an indication of proper operation; and
at least one power converter, coupled to the gateway by a communications channel, for receiving the indication of proper operation and when the indication of proper operation is received, produces power and, when the indication of proper operation is not received, does not produce power,
wherein the indication of proper operation is generated by the gateway while the gateway is connected to the at least one power converter that is connected to a grid and enabled for converting DC power to AC power and transmitting the AC power to the grid and
wherein the indication of proper operation is discontinued upon detection of at least one of: unsafe conditions, maintenance is to be performed, power converter upgrade, or safety hazard.
13. The power generation system of claim 12 wherein the at least one power converter comprises at least one of a microinverter, an inverter, a distributed inverter or a string inverter.
14. The power generation system of claim 12 wherein the indication comprises a communication signal.
15. The power generation system of claim 14 wherein the communication signal comprises a pulse signal.
16. The power generation system of claim 12 wherein the indication is delivered to the at least one power converter via wire, wireless or power line communications.
17. The power generation system of claim 12 wherein the indication of proper operation is discontinued upon detection of at least one of: a fault or unsafe, maintenance is to be performed, an AC power failure, power converter upgrade, or a safety hazard.
18. A gateway for producing an indication of proper operation that, when received by at least one power converter, causes the at least one power converter to produce power and, when the indication of proper operation is not received by the at least one power converter, causes the at least one power converter not to produce power,
wherein the gateway produces the indication of proper operation while the gateway is connected to the at least one power converter that is connected to a grid and enabled for converting DC power to AC power and transmitting the AC power to the grid, and
wherein the indication of proper operation is discontinued upon detection of at least one of: unsafe conditions, maintenance is to be performed, power converter upgrade, or safety hazard.
19. The gateway of claim 18 wherein the at least one power converter comprises at least one of a microinverter, an inverter, a distributed inverter or a string inverter.
20. The gateway of claim 18 wherein the indication comprises a communication signal.
21. The gateway of claim 20 wherein the communication signal comprises a pulse signal.
22. The gateway of claim 18 wherein the indication is delivered to the at least one power converter via wire, wireless or power line communications.
23. The gateway of claim 18 wherein the indication of proper operation is discontinued upon further detection of at least one of: a fault or an AC power failure.
