Enphase IQ8-AC Microinverter

Power your solar system with next-generation efficiency, flexibility, and resilience. The IQ8-AC is Enphase’s grid-forming microinverter, built to maximize energy harvest, support backup power functionality, and simplify system design.

Key Features & Benefits

• High Output & Efficiency — Delely up to 366 VA peak output, with continuous power of ~349 VA at 240 V, and efficiency of ~96.7 %.

• Wide Input Range — Supports module DC inputs from ~295 W up to ~500 W; accepts 18 V to 60 V. 

• Grid-forming Capability — Able to power essential loads even during grid outages (with supporting system components). 

• Module Compatibility — Works with 60-cell and 72-cell (and half-cell) modules with integrated MC4 connectors. 

• Robust & Safe — Built-in protections (over-voltage, over-temperature, anti-islanding) and thermal management for reliability. 

• Industry Warranty — Up to 25 years limited warranty (verify regionally).

Specifications

Applications & Use Cases

• Residential Solar Systems — One microinverter per panel, enabling module-level optimization and monitoring.

• Backup / Resilience Systems — With supporting hardware (batteries, switching gear), the IQ8-AC can help sustain power during grid outages.

• Scalable Installations — Easily scale capacity by adding panels + microinverters without central inverter sizing constraints.

• High-Yield Designs — Pair with high-output PV modules (up to ~500W) while maintaining high efficiency.
