Abstract

A power line communication (PLC) method includes the steps of: programming a registration code into a micro inverter; enabling a data collector to execute a register step, which includes an operation of registering and saving the registration code to a server, through internet; enabling the data collector to send a message to the server through the internet; enabling the server to deliver an authentication code, which is relative to the registration code, to the data collector through the internet according to the message; and enabling the data collector and the micro inverter to identify each other via a power line based on the authentication code.

Claims

1. A power line communication (PLC) method, comprising the steps of:

programming a registration code into a micro inverter;

enabling a data collector to execute a register step, which comprises an operation of registering and saving the registration code to a server, through internet;

enabling the data collector to send a message to the server through the internet;

enabling the server to deliver an authentication code, which is relative to the registration code, to the data collector through the internet according to the message; and

enabling the data collector and the micro inverter to identify each other based on the authentication code via a power line.

2. The method according to claim 1 being applied to narrowband power line communication (PLC).

3. The method according to claim 1, wherein each of the registration code and the authentication code is a bar code.

4. The method according to claim 3, wherein the bar code has 14, 15, 16 or 17 bits.

5. The method according to claim 3, wherein the bar code comprises an origin control code, a product place-of-manufacture code and a product-bar-code check code.

6. The method according to claim 5, wherein the product-bar-code check code is programmed into the micro inverter through an algorithm.

7. The method according to claim 1, wherein the internet is a cloud network.

8. The method according to claim 1, wherein the register step further comprises registering a media access control (MAC) address and a serial number of the data collector.

9. The method according to claim 8, wherein after the register step, the server saves the registration code, the MAC address and the serial number.

10. The method according to claim 8, wherein the message comprises the MAC address of the data collector.

11. The method according to claim 1, wherein the internet comprises a router.

12. The method according to claim 11, wherein the data collector is connected with the router through Ethernet or a wireless network.

13. The method according to claim 11, wherein the server is connected with the router through Ethernet or a wireless network.

14. A power line communication (PLC) system, comprising:

a micro inverter having a registration code;

a data collector connected with the micro inverter via a power line; and

a server connected with the data collector through internet;

wherein the data collector registers and saves the registration code to the server and sends a message to the server through the internet, the server delivers an authentication code, which is relative to the registration code, to the data collector through the internet according to the message, and the data collector and the micro inverter identify each other based on the authentication code via the power line.

15. The PLC system according to claim 14 being applied to narrowband power line communication (PLC).

16. The PLC system according to claim 14, wherein each of the registration code and the authentication code is a bar code.

17. The PLC system according to claim 16, wherein the bar code comprises an origin control code, a product place-of-manufacture code and a product-bar-code check code.

18. The PLC system according to claim 14, wherein the data collector has a media access control (MAC) address and a serial number.

19. The PLC system according to claim 18, wherein the data collector registers the MAC address and the serial number in the server.

20. The PLC system according to claim 18, wherein the message comprises the MAC address of the data collector.
