Abstract

The invention discloses a dynamic parameter conversion method and device for a photovoltaic inverter, and a storage medium. The method comprises the following steps: obtaining a user instruction through a combination assembly; searching a database protocol corresponding to the user instruction in the redis cache according to the user instruction; selecting an algorithm corresponding to a database protocol in a preset algorithm library according to the content of the database protocol, and processing the user instruction to obtain a data instruction; converting the data instruction into a machine instruction by using a system conversion algorithm; and sending the machine instruction to the photovoltaic inverter. The method supports self-defined packaging of a front-end assembly and dynamic configuration of an algorithm library and a conversion algorithm, is suitable for operation of massive protocols, calculation of various Modbus protocol address data and conversion of various data, and is widely applied to the field of photovoltaic inverter control.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular a dynamic parameter conversion method for a photovoltaic inverter, an apparatus and a storage medium. Background [0002] Photovoltaic inverters are the core components of photovoltaic power generation systems and are used to convert direct current generated by photovoltaic solar panels into alternating current. The inverter has more than 1,000 configurable parameters and will continue to change as inverter technology innovates. The existing parameter change mode operation is complex, single choice, text input, multi-instruction compounding and other ways are numerous; how to efficiently carry out dynamic conversion of inverter parameters, how to let users simply set parameters, is a technical problem that those skilled in the art need to solve. [0003] The modbus protocol is a data transmission protocol for communication between the data acquisition module and the platf...
