Business Description

Enphase Energy, Inc. | 2025 Form 10-K | 6 Table of Contents Our Company We are a global energy technology company originally founded in March 2006. We deliver smart, easy-to-use solutions that manage solar generation, storage and communication on one platform. Our intelligent microinverters work with virtually every solar panel made, and when paired with our smart technology, result in one of the industry’s best-performing clean energy systems. For the first time in the evolution of our 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 our lives and ultimately help greatly reduce our dependence on fossil fuels. As of December 31, 2025, we have shipped approximately 86.4 million microinverters, and more than 5.1 million Enphase residential and commercial systems have been deployed in over 160 countries. We design, develop, manufacture and sell home energy solutions that manage energy generation, energy storage, and control and communications on one intelligent platform. We have 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 our proprietary networking and software technologies, provides advanced energy monitoring and control. This is vastly different than a string inverter system using string modules, whether with or without an optimizer, which only converts the energy of the entire array of solar modules from a single high voltage electrical unit and lacks intelligence about the energy producing capacity of the solar array. The Enphase ® Energy System brings a high technology, networked approach to solar generation plus energy storage, by leveraging our design expertise across power electronics, semiconductors and cloud-based software technologies. Our integrated approach to energy solutions maximizes a home’s energy potential while providing advanced monitoring and remote maintenance capabilities. The Enphase Energy System uses a single technology platform for seamless management of the whole solution, of IQ ® Microinverters, IQ ® Batteries, IQ ® Load Controllers, and IQ ® EV Charger, allowing rapid commissioning with the Enphase ® Installer App, consumption monitoring with our IQ ® Combiner™ device with our Enphase IQ ® Gateway™ device, and our Enphase ® App, a cloud-based energy management platform. System owners can use the Enphase App to monitor their home’s solar generation, energy storage and consumption from any web-enabled device. Unlike some of our competitors, who utilize a traditional inverter, or offer separate components of solutions, we have built-in system redundancy in both photovoltaic (“PV”) generation and energy storage, eliminating the risk that comes with a single point of failure. Further, the nature of our cloud-based, monitored system allows for remote firmware and software updates, enabling cost-effective remote maintenance and ongoing utility compliance. We have transitioned from solar only systems to complete energy management solutions, which consist of solar, batteries, load control, electrical vehicle (“EV”) charging, compatibility with third-party generators, and grid services. This transition follows the rising global interest in the full electrification of homes and businesses through renewable sources of energy. Our Strategy Our objective is to build best-in-class home energy systems and deliver them to homeowners through our installer and distribution partners, enabled by a comprehensive digital platform. Key elements of our strategy include: • Best-in-class customer experience. Our value proposition is to deliver products that are productive, reliable, smart, simple and safe, with superior customer service, to enable homeowners’ storage and energy independence. On the service front, our installer, distributor and module partners are our first line of association with our ultimate customer, the homeowner and business user. Our goals are to partner better with these service providers so that we can provide exceptional, high quality service to homeowners who have installed our products.…
