Power carrier communication micro inverter

A communication method with strong reliability, low cost and easy maintenance is the key to photovoltaic inverter communication.At present, the most common method is through wireless ( such as WIFI / LoRa ), RS485 and power line carrier ( PLC ) communication.The wireless communication scheme does not need wiring, which can save the investment of communication cable and line laying construction, but it has some harsh environmental requirements, and is obviously blocked by the battery plate and electromagnetic wave interference.
