        Market Definition

        A micro-inverter is a device used in solar photovoltaic (PV) systems to convert direct current (DC) electricity generated by individual solar panels into alternating current (AC) electricity. Unlike traditional string inverters, which are designed to handle the output of multiple solar panels in a series, micro-inverters operate on a per-panel basis. Micro-inverters are often more flexible in terms of system design and installation. They can be used in complex roof layouts or situations where shading is a concern, offering greater design flexibility. The micro-inverters are used for applications such as residential, commercial, and PV power plants.
