Enphase IQ8X-80-M-US Microinverter

The Enphase IQ8X-80-M-US is a high-performance microinverter from the IQ8 Series, specifically designed for the latest generation of high-powered solar PV modules. As part of Enphase’s industry-leading microinverter lineup, it features microgrid-forming capability (when paired with an IQ System Controller), enabling off-grid operation during outages as part of a full Enphase Energy System.

Key Features

• Industry-first microgrid-forming and software-defined design with split-phase power conversion for efficient DC-to-AC conversion.
• Proprietary ASIC (application-specific integrated circuit) in advanced 55 nm technology for superfast response to load and grid changes, supporting grid-tied and off-grid modes while easing battery sizing constraints in home energy systems.
• Optimized for high-voltage, high-output PV modules, including those with 80-half-cell, 88-half-cell, and 96-cell configurations (commonly paired with 320–540 W modules).
• Integrated Stäubli MC4 DC connectors for quick, plug-and-play module connections.
• Lightweight, compact, fanless design with natural convection cooling for reliable outdoor performance.
• Part of the Enphase Energy System, integrating seamlessly with IQ Batteries, IQ Gateway, and the Enphase App for monitoring and control.
• Rapid shutdown compliance and low-voltage DC for enhanced safety and fire protection.
• Industry-leading up to 25-year limited warranty (when installed with an internet-connected IQ Gateway).
