Enphase Energy ships IQ battery 10C with domestic content

Enphase Energy (ENPH) announced initial shipments of the IQ Battery 10C supplied from manufacturing facilities in the United States, delivering significant value in the growing third-party ownership, TPO, market. The IQ Battery 10C includes domestically sourced or manufactured components to help projects qualify for key federal tax credits. The federal budget law signed in July 2025 enforces a 45% U.S.-sourced materials threshold for solar and battery products to be eligible for the domestic content bonus tax credit. This threshold will increase to 50% in 2026 and 55% in 2027. The IQ Battery 10C units with domestic content will meet these higher standards – not just for today’s 45% requirement, but also for currently anticipated future thresholds. The new battery has already been added to approved vendor lists for several major TPO providers and gives companies the ability to capture significant tax credit value.
