Enphase Energy Begins Shipments of IQ Battery 5P with Higher Domestic Content to Meet New U.S. Federal Requirements
FREMONT, Calif., July 17, 2025 (GLOBE NEWSWIRE) -- (NASDAQ: ENPH), a global energy technology company and the world's leading supplier of microinverter-based solar and battery systems, today announced initial shipments of the IQ® Battery 5P supplied from manufacturing facilities in the United States with higher domestic content than previous models. The higher domestic content batteries comply with the new requirement in the U.S. federal budget law, signed on July 4, 2025, which retroactively enforces a 45% U.S.-sourced materials threshold for solar and battery products starting June 16, 2025.
To remain eligible for key federal tax incentives, products must meet this threshold, which will increase to 50% in 2026 and 55% in 2027, where it will remain in effect at that level thereafter. The new units with “DOM” SKUs (IQBATTERY-5P-1P-NA-DOM) are being built now to meet these higher standards — not just for today’s 45% requirement, but also for all expected future thresholds — thanks to the substantial use of U.S.-sourced materials. These batteries are helping support American jobs and manufacturing, and a more resilient domestic supply chain.
“Our customers consistently want Enphase for the seamless integration between their solar and storage systems,” said Joel McClure CEO of NexGen Solar, an installer of Enphase products in California. “The IQ Battery 5P's modular design allows us to right-size each installation, and the increased domestic content helps customers comply with evolving federal requirements.”
“Enphase continues to lead with reliable, high-performance energy storage solutions,” said Orlando Diaz, CEO of Planet Solar, an installer of Enphase products in Puerto Rico. “With the IQ Battery 5P now meeting the new federal domestic content requirements, our customers can benefit from lower costs on our offering with a product that’s built for resilience and long-term value.”
The IQ Battery 5P is a modular design with a 5 kWh capacity and can be paired with Enphase IQ8™ Microinverters to provide homeowners with reliable electricity to use whenever they need it. Homeowners can also use the Enphase® App to monitor performance and intelligently manage their battery systems, including the self-consumption feature to reduce the use of electricity from the grid.
“We’re pleased to begin U.S. shipments of the IQ Battery 5P with increased domestic content,” said Ken Fong, senior vice president and general manager of the Americas and APAC at Enphase Energy. “The IQ Battery 5P delivers top-tier performance, and now, with domestic content that meets the latest federal requirements, our installer partners are better positioned to enjoy the value of federal tax incentives, grow their businesses, and bring energy storage to more homes across the country.”
