Description

A method and apparatus for automatically mapping inverters of photovoltaic modules The present invention relates to a method and apparatus for automatically mapping an inverter of a solar 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 solar power generation system, and each module includes a micro-inverter that performs the role of converting the generated energy. After installing multiple PV modules, the installer must perform the process of mapping them onto a layout diagram. At this stage, the installer faces the inconvenience of having to manually scan codes containing identification information for each PV module or micro-inverter one by one and then individually match that identification information with the location information where the PV module or micro-inverter is placed. Therefore, various methods are being researched to simplify this process. The aforementioned background technology is technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot be considered as prior art disclosed to the general public prior to the filing of the present invention.
