Enphase IQ8P Microinverter — IQ8P-3P-72-E-DOM-US-2545
Domestic Content Model | 480 VA Peak Output | 475 VA Continuous Output | 208Y Vac Three-Phase | 72-Cell / 144 Half-Cell Modules | Smart Grid Ready | 97.5% CEC Efficiency | 25-Year Limited Warranty
Product Overview
The Enphase IQ8P Microinverter IQ8P-3P-72-E-DOM-US-2545 is a high-powered, smart grid-ready microinverter designed for 208Y Vac three-phase commercial solar installations. Built for 72-cell and 144 half-cell modules, it delivers 480 VA peak output power and 475 VA continuous output while providing module-level conversion and monitoring through the Enphase ecosystem. Its domestic-content designation makes it a strong fit for projects that require U.S.-made hardware for procurement or incentive purposes.
As part of the IQ Series, this microinverter is engineered for long-term reliability, advanced grid support, and simplified installation. It integrates with the IQ Gateway Commercial 2 and the Enphase App for monitoring, diagnostics, and fleet management, helping installers and system owners maintain clear visibility into performance and uptime.
Key Benefits
High-Power Module-Level Conversion: The IQ8P delivers 480 VA peak output and 475 VA continuous output at the module level, helping maximize energy harvest on commercial and larger distributed solar projects.
Three-Phase Commercial Support: Designed for 208Y Vac three-phase systems, it fits small commercial applications where balanced three-phase interconnection is required.
Domestic Content Version: The DOM-US designation supports projects that need U.S.-manufactured equipment for compliance, procurement, or incentive goals.
Smart Grid Ready: Advanced grid support features and remote automatic updates help the inverter stay aligned with evolving utility requirements over time.
Enphase Monitoring Ecosystem: Integration with the IQ Gateway Commercial 2 and Enphase App simplifies commissioning, monitoring, and maintenance across the site.
How It Works
The IQ8P microinverter mounts beneath a single PV module and converts the panel's DC output into grid-synchronized AC power at the module level. In a three-phase installation, the microinverters are distributed across the array to support 208Y Vac interconnection, while power line communication and the IQ Gateway Commercial 2 collect performance data for monitoring and control. This architecture helps improve system design flexibility, module-level visibility, and operational reliability.
Module-Level MPPT: Each microinverter independently tracks its attached module to optimize output under changing irradiance and temperature.
Grid Integration: The system supports advanced grid requirements and communicates with the Enphase ecosystem for fleet-wide management.
Monitoring and Updates: Installers and owners can monitor production and receive updates through the Enphase App and compatible gateway hardware.
