PHOTOVOLTAIC MANAGEMENT AND MODULE-LEVEL POWER ELECTRONICS

摘要

A photovoltaic (PV) system includes module-level power electronic (MLPE) devices that produce energy. The PV system includes a gateway to receive and send data to MLPE devices. The gateway also connects the PV system with a network, such as a local area network, that allows access to the Internet. The gateway provides functionality within the PV system to perform various processes to improve operation of MLPE devices.

主权项

1. A method for measuring signal quality for a communication channel used by a photovoltaic (PV) system, the method comprising:
generating a first message; transmitting the first message at a time 1 from a gateway to a first module-level power electronic (MLPE) device within the PV system; generating a second message; transmitting the second message at a time 2 from the gateway to a second MLPE device within the PV system; and listening for a response to the first message,
wherein transmitting the second message at time 2 is started in violation of a communication protocol used by the MLPE and is transmitted during a period of time when a message sender should instead be listening for a response to the first message.
