Description

A method and apparatus for automatically mapping an MLPE device in photovoltaic modules The present invention relates to a method and apparatus for automatically mapping an MLPE device of a photovoltaic module. With the recent increase in interest in eco-friendly energy technologies, the installation of solar power generation systems is on the rise. A solar power generation system produces electricity by collecting solar energy through solar modules; this generated electricity is supplied to the household power grid for household use or stored in batteries for later use. Producing electricity through solar power systems is environmentally friendly and can lead to reduced electricity bills in the long run, which is why they have recently been gaining popularity. Generally, multiple photovoltaic (PV) modules are installed in a photovoltaic power generation system, and each photovoltaic module includes an MLPE device that optimizes power generation and manages power conversion. After installing multiple photovoltaic modules, the installer must perform the process of mapping them to a layout diagram. At this time, the installer faces the inconvenience of having to manually scan codes containing identification information for each photovoltaic module or MLPE device one by one, and then individually match the identification information of the photovoltaic module or micro-inverter with the location information where the photovoltaic module or device is installed. Therefore, various methods are being researched to simplify this process.
