The new IQ Battery 5P units are designed to meet all expected future thresholds, supporting American jobs and manufacturing. The battery can be paired with Enphase IQ8 Microinverters and monitored through the Enphase App to manage energy usage.

Enphase Energy, Inc. (NASDAQ: ENPH) has begun shipping its IQ Battery 5P with higher domestic content to meet new U.S. federal requirements. The batteries comply with a 45% U.S.-sourced materials threshold for solar and battery products, which will increase to 50% in 2026 and 55% in 2027. The new IQ Battery 5P units are designed to meet all expected future thresholds, supporting American jobs and manufacturing.

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.

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 [1].

Installers of Enphase products, such as NexGen Solar and Planet Solar, are pleased with the new IQ Battery 5P. They appreciate the seamless integration between solar and storage systems, the modular design allowing them to right-size each installation, and the increased domestic content helping customers comply with evolving federal requirements [1].

Enphase Energy's CEO, Ken Fong, expressed his satisfaction with the launch of the IQ Battery 5P. He noted that the battery delivers top-tier performance and is now built to meet the latest federal requirements. This positioning helps installer partners enjoy the value of federal tax incentives, grow their businesses, and bring energy storage to more homes across the country [1].

The IQ Battery 5P is a significant step forward in Enphase's commitment to reliable, high-performance energy storage solutions. By meeting the new domestic content requirements, Enphase is not only supporting American manufacturing but also positioning itself for future regulatory changes.
