Enphase Energy, Inc. 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 IQ Battery 5P 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 -- due to the substantial use of U.S.-sourced material. These batteries are helping support American jobs and manufacturing, and a more resilient domestic supply chain.
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.
