Enphase Energy and Ensol Partner to Expand Home Battery Adoption in France

FREMONT, Calif., March 16, 2026 (GLOBE NEWSWIRE) -- Enphase Energy, Inc. (NASDAQ:ENPH), a global energy technology company, today announced a collaboration with Ensol, a residential solar and storage provider in France, to expand IQ^® Battery deployments through Ensol's battery subscription program for French homeowners. The program makes Enphase^® battery storage more accessible through a monthly subscription model, with plans starting at €30 per month.

Ensol installs the IQ Battery 5P and manages the system under a fixed monthly subscription that includes monitoring, maintenance, and Enphase's industry-leading 15-year warranty. Beginning in the third year, homeowners have the option to continue the subscription, purchase the battery at its residual value, or exit the program. Ensol also aggregates enrolled batteries into a virtual power plant (VPP) that participates in demand response programs through Réseau de Transport d'Électricité (RTE), France's primary transmission system operator (TSO). This benefit flows back to homeowners in the form of reduced monthly costs, without changing their comfort or energy experience.

"Enphase's IQ Battery 5P is an ideal fit for our subscription model – premium performance, proven reliability, and a 15-year warranty that gives our customers added peace of mind," said Martin D'Hoffschmidt, co-founder of Ensol. "Through our innovative program, French homeowners can get a fully managed home battery starting at €30 a month through a simple subscription model."

The IQ Battery 5P is a powerful and flexible home battery system designed for modern households. This all-in-one AC-coupled solution starts at 5 kWh of usable capacity and can be scaled up to 70 kWh to meet a home's energy needs. FlexPhase™ technology supports both single-phase and three-phase electrical configurations, making it suitable for a wide range of residential installations in France. PowerMatch™ technology dynamically adjusts the IQ Battery output to match a home's real-time power demand, helping reduce low-load efficiency losses and deliver more usable energy and greater long-term savings for homeowners. The IQ Battery 5P is backed by an industry-leading 15-year warranty.

"France has millions of solar homes that are ready for storage, but upfront cost has often been the biggest barrier," said Sabbas Daniel, senior vice president of sales at Enphase Energy. "Ensol's subscription model helps remove that barrier. With a fixed monthly subscription that includes monitoring, maintenance, and a 15-year warranty, homeowners have a compelling path to greater energy independence and resilience."

Additionally, Enphase is conducting homeowner engagement events in 2026 to raise awareness of programs and offers that support battery adoption in France and the Netherlands. Enphase expects to host hundreds of in-person events focused on solar-only homeowners who have not yet added battery storage. These events are designed to educate homeowners about the financial and resilience benefits of adding an IQ Battery to an existing Enphase solar system.
