Enphase shipping IQ Battery 5P with more domestic content
Enphase Energy announced initial shipments of the IQ Battery 5P supplied from manufacturing facilities in the United States with higher domestic content than previous models. This is especially relevant after the signing of the OBBB on on July 4, 2025, which retroactively enforces a 45% U.S.-sourced materials threshold for solar and battery products starting June 16, 2025.
“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 “DOM” SKUs
To remain eligible for the domestic content adder of the investment tax credit 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 thresholds, the company says, with substantial use of U.S.-sourced materials.
“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.”
IQ Battery 5P
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.
