Enphase IQ8AC 349VA Continuous / 366VA Peak Microgrid-Forming Microinverter – IQ8AC-72-M-US

The Enphase IQ8AC-72-M-US IQ8AC Microinverter is an advanced, high-efficiency solar microinverter designed to convert direct current (DC) electricity from individual photovoltaic modules into grid-compatible alternating current (AC) electricity. Featuring a peak output power of 366VA at 240V and a maximum continuous output of 349VA, the IQ8AC provides reliable module-level power conversion for modern residential solar installations.

Part of the innovative Enphase IQ8 Series, this microinverter features proprietary microgrid-forming technology powered by an advanced application-specific integrated circuit (ASIC). This semiconductor-based design enables rapid response to changing grid conditions and supports grid-tied and properly configured off-grid operating modes.

The IQ8AC is optimized for modern high-powered photovoltaic modules and features integrated Stäubli MC4 connectors for simplified installation. Its compact, lightweight design, plug-and-play connectivity, and power line communication (PLC) technology help streamline installation and system integration.

Designed to operate as part of the Enphase Energy System, the IQ8AC integrates with compatible IQ Gateway monitoring equipment, IQ Batteries, and the Enphase App to provide intelligent solar energy management and system monitoring.

Important: Off-grid operation and solar production during utility outages require a compatible Enphase system configuration, including the appropriate IQ System Controller and other required equipment. The microinverter does not independently provide backup power during a grid outage.

Compatibility Note: IQ8 Series Microinverters cannot be mixed with previous Enphase microinverter generations, including IQ7 and IQ6 Series, within the same system.
