Smart design for faster installation

The IQ8M is engineered for simplicity and speed. Its plug-and-play MC4 connectors and two-wire cabling system streamline setup, minimizing labor and wiring complexity. Each unit connects to a single solar module, allowing precise system scaling for any array size. Power Line Communication (PLC) enables seamless communication across the Enphase ecosystem without extra wiring or external gateways.

Resilient, high-performance operation

Built with Enphase’s proprietary ASIC technology, the IQ8M reacts in milliseconds to shifts in grid or load conditions, ensuring stable operation and maximizing energy harvest. It’s optimized for the latest high-power PV modules (260–460 W range) and can continue producing energy during grid outages when paired with the Enphase IQ System Controller 2—delivering true energy independence.

Safety and compliance built in

The IQ8M meets CA Rule 21, UL 1741-SB, and IEEE 1547:2018 requirements, ensuring compliance with evolving grid standards. Integrated rapid shutdown capability and Class II double insulation provide industry-leading protection for installers and homeowners alike. Its NEMA Type 6 enclosure and corrosion-resistant polymer housing are designed for long-term outdoor exposure.

Smarter energy management

As part of the Enphase Energy System, the IQ8M integrates seamlessly with IQ Batteries, the IQ Gateway, and the Enphase App for real-time monitoring, energy insights, and remote firmware updates. The system supports remote configuration for a wide range of grid profiles and includes automated compliance updates for changing regulations.

Reliable, silent, and efficient

Featuring natural convection cooling and no moving parts, the IQ8M operates silently with minimal maintenance. With 97.5% CEC efficiency and over one million hours of reliability testing, it stands among the most durable and efficient microinverters on the market—delivering stable, clean energy for decades.
