Next-generation power conversion

The IQ8AC utilizes Enphase’s advanced ASIC (Application-Specific Integrated Circuit) to deliver fast, precise power conversion and real-time grid responsiveness. Supporting both grid-tied and microgrid operation, it produces reliable AC power even during grid outages when installed with an IQ System Controller. This intelligent technology ensures optimized solar output and energy security in all conditions.

High performance and reliability

With 97.3% peak efficiency and 97.0% CEC weighted efficiency, the IQ8AC maximizes energy harvest across varying light conditions. Each unit undergoes over one million cumulative hours of reliability testing to ensure long-term performance. Its fanless, naturally cooled design minimizes maintenance while the corrosion-resistant polymeric enclosure ensures superior weather protection for rooftop and ground-mounted systems.

Smart grid-ready and compliant

Fully compliant with UL 1741-SB (3rd Edition), IEEE 1547:2018, and CA Rule 21, the IQ8AC is ready for the evolving smart grid. It supports Volt-Var, Volt-Watt, and Frequency-Watt control modes, allowing advanced grid interaction and remote firmware updates for future standards. This ensures long-term adaptability and compliance with NEC 2014, 2017, 2020, and 2023 rapid shutdown requirements.

Seamless integration and monitoring

The IQ8AC communicates via Power Line Communication (PLC) with the IQ Gateway and integrates easily into the Enphase Energy System for centralized control and monitoring. Through the Enphase App, system owners can track real-time energy production, analyze performance, and receive automatic updates, ensuring optimal system operation with minimal oversight.

Compact, lightweight, and installer-friendly

Weighing just 2.43 lb, the IQ8AC’s compact form factor allows fast, simple installation using plug-and-play connectors. Up to 11 units can be connected per 240V branch circuit (or 9 at 208V), reducing wiring complexity and balance-of-system costs. Its Stäubli MC4 DC connectors and two-wire cabling simplify setup while ensuring secure electrical connections.
