Problems solved by technology

Although this method can avoid the mutual influence between different photovoltaic inverter systems, the actual operation is too complicated for large-scale application
In addition, if the inverter or communicator in the system fails and needs to be replaced, the new device must know the PANID of the system to join the network, which will bring a lot of inconvenience in actual operation

Abstract

The invention provides an inverter system communication networking method. An inverter system comprises one or a plurality of photovoltaic assemblies, one or a plurality of inverters correspondingly connected with the photovoltaic assemblies, a communicator, a server and grid ports. Each inverter is connected with a bus cable to be connected with an alternating current power grid through a grid port. One end of the communicator is connected with the one or the plurality of inverters through a wireless personal local area network technology, and the other end of the communicator is connected with the server through the Internet. The communication networking method mainly includes that the communicator informs one or the plurality of inverters to modify personal area network identifiers of the inverters to be a personal area network identifier of the communicator, and the communicator reads short addresses of the inverters. The method can be used in the system with the single photovoltaic inverter or the plurality of photovoltaic inverters, achieves networking operation conveniently, reduces the system networking time and removes mutual interference between the devices and between the systems.

Description

technical field [0001] The present invention relates to the technical field of communication of photovoltaic inverters, in particular, the present invention relates to a communication networking method of an inverter system. Background technique [0002] ZigBee is a wireless personal area network (WPAN, Wireless Personal Area Network) protocol based on the IEEE802.15.4 standard, and it is also a low-power, low-cost, high-reliability wireless networking communication technology. ZigBee adopts self-organizing network and dynamic routing to establish and maintain the network, and distinguishes each independent network with a personal area network identifier (PANID, Personal Area Network ID). Networks under different PANIDs can operate independently and are independent of each other. interference. [0003] ZigBee technology can be used in photovoltaic inverter systems to realize the connection between inverters and communication equipment, and complete data transmission and com...
