Enphase Energy, Inc. (Enphase) operates as a global energy technology company.
The company delivers smart, easy-to-use solutions that manage solar generation, storage and communication on one platform. The company’s intelligent microinverters work with virtually every solar panel made, and when paired with the company’s smart technology, results in one of the industry’s best-performing clean energy systems.
For the first time in the evolution of the company’s centuries-old grid, people can get paid for the clean energy they produce and share with their communities, helping to build a new energy future that harnesses the sun. This clean, free, abundant source of energy can power the company’s lives and ultimately help replace fossil fuels altogether. The company has shipped more than 80.0 million microinverters, and approximately 4.7 million Enphase residential and commercial systems have been deployed in more than 160 countries.
The company designs, develops, manufactures, and sells home energy solutions that manage energy generation, energy storage, and control and communications on one intelligent platform. The company has revolutionized the solar industry by bringing a systems approach to solar technology and by pioneering a semiconductor-based microinverter that converts energy at the individual solar module level and combined with the company’s proprietary networking and software technologies, provides advanced energy monitoring and control.
