Enphase's newest IQ8+ Microinverters are the industry's first grid-forming microinverters with split-phase power conversion capability to convert DC power to AC power efficiently.

The brain 🧠 of the semiconductor-based microinverter is the proprietary application-specific integrated circuit (ASIC) which enables the microinverter to operate in grid-tied or off-grid modes. This chip is built in advanced 55 nm technology with high-speed digital logic and has super-fast response times to changing loads and grid events, alleviating constraints on battery sizing for home energy systems.

Part of the Enphase Energy System, IQ8+ Microinverters integrate with the Enphase IQ Battery, Enphase IQ Gateway, and the Enphase App monitoring and analysis software. IQ8+ Microinverters redefine reliability standards with more than one million cumulative hours of power-on testing, enabling an industry-leading limited warranty of up to 25 years.

The IQ8P Microinverter is a higher powered, 480 VA rated, smart-grid ready microinverter designed to match larger format residential and commercial PV modules. The IQ8P Microinverter has the highest energy production and reliability standards in the industry, and with rapid shutdown functionality, it meets the highest safety standards.

The brain of the semiconductor-based microinverter is our proprietary, application-specific integrated circuit (ASIC) that enables the microinverter to operate reliably in grid-connected mode. The IQ8 Series Microinverters redefine reliability standards with over one million cumulative hours of power-on testing, enabling an industry-leading warranty of 25 years.

The IQ9S-3P Microinverter delivers unmatched power for commercial solar projects. With a peak AC output of 548 VA, support for 18 A continuous input current, and compatibility with high-wattage modules up to 770 W, it’s built to handle today’s most demanding panels for large-scale commercial installations.

Powered by advanced GaN-based architecture and the trusted Enphase platform, IQ9S-3P delivers superior energy harvest, long-term reliability, and seamless integration with the IQ Gateway Commercial Pro, QD Cables, and the Enphase App—providing complete visibility and control from anywhere.

Designed for 480 VAC three-phase systems, IQ9S-3P simplifies commercial solar with native support for 277 V (L-N) grids. Built-in safety features like rapid shutdown, phase balancing and voltage/frequency ride-through ensure compliance, while remote diagnostics and fleet-wide monitoring reduce site visits and maximize uptime.
