Because the traditional inverter communication monitoring method relics on manual inspection and regular maintenance,it is not only inefficient,but also difficult to accurately find potential faults,so an automatic monitoring method of renewable energy grid-connected inverter communication is proposed.Monitor the key communication signals,such as voltage,current,power,temperature and humidity,in the communication of renewable energy grid-connected in-verter,and do a series of pre-processing for them,build the communication signal after CNN model input and processing,identify the communication fault category of the inverter,and com-plete the automatic monitoring of renewable energy grid-connected inverter communication.The experimental results show that the missing alarm rate and error alarm rate of inverter com-munication fault monitoring results and high accuracy are low.
