POWER LINE COMMUNICATION ROUTING SYSTEM AND METHOD OF OPERATING THE SAME

摘要

A power line communication (PLC) routing system includes a plurality of micro inverters and a data collection apparatus connected to the micro inverters through a power line. After being installed in the building, the micro inverters are registered to the data collection apparatus. When submitting a connection request to the micro inverters but cannot receive the corresponding response, the data collection apparatus commands a micro inverter which has responded the request to transmit the request to another micro inverter which is out of time to response, and re-transmits data from the another micro inverter to the data collection apparatus.

主权项

1. A power line communication routing system comprising:
a power line; a plurality of micro inverters connected to the power line, each micro inverter having a solar panel and a DC-to-AC converter; the DC-to-AC converter electrically connected to the solar panel and the power line, and configured to output an AC power through the power line; and a data collection apparatus connected to the power line, and configured to submit requests to the micro inverters and receive responses transmitted from the micro inverters; wherein the data collection apparatus is configured to regard the micro inverter as a first-type micro inverter when the micro inverter does not submit the response within a predetermined time, and command a second-type micro inverter of the micro inverters to submit the request instead of the first-type micro inverter; the second-type micro inverter is configured to receive the data replied from the first-type micro inverter through the power line, and transmit the received data to the data collection apparatus through the power line.
