A microinverter is a small device used in solar energy systems to convert direct current (DC) generated by individual solar panels into alternating current (AC) for use in homes or businesses. Unlike traditional string inverters that connect multiple panels together, microinverters are attached to each panel, allowing for better energy optimization and monitoring. This technology enhances the overall efficiency of solar installations, especially in situations where panels may be shaded or oriented differently. By maximizing the output of each panel, microinverters can lead to increased energy production and improved performance over time, making them a popular choice for many solar energy users.
