Microinverter
A microinverter is a small device that converts solar energy from solar panels into usable electricity for homes and businesses. Unlike traditional systems that use one large inverter for many panels, microinverters work individually on each solar panel. This is like having a tiny power plant for each panel instead of one big power plant for all panels. Companies like Enphase and APsystems are well-known makers of these devices. Think of it as a translator that changes the solar panel's "language" (DC power) into the "language" your home uses (AC power), but does it right at each panel for better efficiency.
