Enphase Energy is a NASDAQ-listed energy technology company headquartered in Petaluma, California. Enphase designs and manufactures software-driven home energy solutions that span solar generation, home energy storage and web-based monitoring and control. Microinverters convert the direct current power from the solar panel (DC) directly into grid-compatible alternating current (AC). Enphase was the first company to successfully commercialize the microinverter on a wide scale, and remains the market leader. Because they function independently there no single point of failure in a microinverter system and one shaded or dirty panel will not affect the rest of the system. These microinverters also use burst technology for an optimized power production yield at dawn, dusk and during low-lights conditions.
As of 2012, their inverters captured 53.5% market share for residential installations in the US, which represents 72% of the entire world micro-inverter market. This makes them the sixth largest inverter manufacturer, of any kind, worldwide.
