The invention relates to a monitoring management method of a mini inverter. OFDM power line carriers of high anti-interference capability are used, a built-in OFDM power line carrier module and a datacollecting and uploading terminal are designed, power generation information of a photovoltaic power station is stored in a cloud-end database via power-line carrier communication, a server establishes a fault diagnosis model, a lot of data is monitored, counted and analyzed in real time, and events, as local shadow, assembly hot spots, assembly abnormal aging and system interconnected line break, that influence the generating capacity and safety of the power station are obtained timely, an owner of the photovoltaic power station is notified by short messages and alarming in the monitoring interface, faults and hidden safety hazards are checked, and the power station is maintained intelligently.
Description
technical field [0001] The invention relates to a method for monitoring and managing a micro-inverter. Background technique [0002] Traditional inverters use 485 data lines for communication, and the on-site wiring of the system is complicated; some manufacturers use wifi wireless communication solutions. Although communication cables are omitted, this solution has limitations in communication distance, wall penetration ability, and electromagnetic environment resistance. The problem is that the field use effect is not satisfactory. Contents of the invention [0003] The invention relates to a method for monitoring and managing a micro-inverter. This method adopts the OFDM power line carrier with strong anti-interference ability, and provides a closed environment for the micro-inverter system by designing a matching power line carrier wave trap, so that the communication line can be saved and the communication reliability can be ensured. This method introduces cloud int...
