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 present invention provides a communication networking method for an inverter system. The inverter system includes one or more photovoltaic modules, one or more inverters correspondingly connected to the photovoltaic modules, a communicator, a server, and a power grid interface; The inverter is connected to a bus cable and then connected to an AC grid through the grid interface; one end of the communicator is connected to one or more inverters through the wireless personal area network technology, and the other end is connected to the server through the Internet. The communication networking method mainly includes the steps of the communicator notifying one or more inverters to modify their personal area network identifiers to the personal area network identifiers of the communicators, and the step of the communicators reading the short addresses of the inverters. The present invention can be used in single or multiple photovoltaic inverter systems with multiple inverters, realizes convenient networking operation, shortens the time of system networking, and eliminates the gap between equipment and equipment and between systems. interfere with each other.

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...
