Engineered for commercial flexibility

The IQ8P-3P is purpose-built for three-phase 208 V systems, making it an ideal choice for small to mid-sized commercial solar arrays. Its modular microinverter design allows for flexible system scaling, reduced single-point failure risk, and simplified maintenance. Each unit connects to a single PV module, enabling precise power optimization across arrays and easier system expansion.

High efficiency and advanced reliability

Delivering 97.5% CEC-weighted efficiency and 97.8% peak efficiency, the IQ8P-3P maximizes power conversion while maintaining stability under varying conditions. The unit is built to last, featuring over a million hours of reliability testing and a rugged polymeric housing rated for harsh environments. Its double-insulated, fanless design ensures quiet, efficient operation with minimal maintenance needs.

Grid-interactive and smart grid ready

With built-in support for advanced grid functionalities such as Volt-Var, Volt-Watt, and Frequency-Watt control, the IQ8P-3P meets the latest CA Rule 21 and UL 1741-SB requirements. It’s capable of remote firmware updates via the Enphase App, ensuring ongoing compliance with evolving grid standards. The system automatically adapts to multiple grid profiles for deployment flexibility across regions.

Seamless integration and monitoring

Using Power Line Communication (PLC), the IQ8P-3P seamlessly connects with the IQ Gateway Commercial 2 and Enphase App for real-time performance tracking, diagnostics, and analytics. Installers and owners benefit from simplified commissioning, remote oversight, and centralized energy management across multi-inverter systems.

Safe, weatherproof, and installation-ready

The IQ8P-3P’s NEMA Type 6/IP67-rated enclosure offers full protection against dust and water ingress, making it suitable for outdoor mounting in any climate. With plug-and-play EN4 connectors and Stäubli MC4 adapter cables, installation is fast and straightforward. Each inverter supports up to 12 units per 20A three-phase branch circuit, streamlining design and reducing wiring complexity.
