A micro-inverter is a type of power electronics device used in solar energy systems. It is designed to convert direct current (DC) generated by individual solar panels into alternating current (AC) used in most household electrical systems. The primary purpose of a microinverter is to maximize the energy harvest from each solar panel and optimize the overall performance of a solar installation.

Unlike traditional solar inverters, which are typically centralized and handle the output of multiple solar panels, microinverters are installed directly on each individual solar panel. This means that each solar panel in a system has its own dedicated microinverter.
