Made in USA for maximum performance and compliance

The IQ8P-3P-72-E-DOM-US model is proudly manufactured in the United States, with domestic PCBA, enclosure, and electrical components—meeting ITC domestic content requirements. It combines Enphase’s advanced microinverter architecture with robust U.S. engineering standards to deliver reliable, grid-compliant energy conversion for small to mid-scale commercial installations.

Smart grid-ready and future-proof

Engineered for the modern grid, the IQ8P-3P supports IEEE 1547 (UL 1741-SB) and CA Rule 21 standards, offering advanced functions such as Volt-Var, Volt-Watt, and Frequency-Watt control. Automatic remote firmware updates via the Enphase App ensure ongoing compliance with evolving utility requirements and maintain peak system performance without manual intervention.

High reliability and intelligent design

With over one million hours of reliability testing, this inverter is built for long-term performance in demanding conditions. The corrosion-resistant polymeric enclosure and IP67 weatherproof rating protect against dust, water, and UV exposure, while natural convection cooling ensures efficient thermal management with no moving parts. Its high conversion efficiency maximizes energy harvest while minimizing losses.

Seamless monitoring and integration

The IQ8P-3P integrates effortlessly with the IQ Gateway Commercial 2 and Enphase App for detailed, real-time monitoring of system performance. The Power Line Communication (PLC) interface eliminates the need for extra communication wiring, simplifying installation and reducing maintenance costs across multi-inverter systems.

Fast installation and flexible scalability

Compact and lightweight at 3.5 lb, the IQ8P-3P is designed for quick installation using plug-and-play connectors and preconfigured branch circuits. It supports up to 12 microinverters per 20A three-phase branch circuit, making it scalable for larger arrays. Its wide module compatibility ensures flexibility across a range of project designs.
