Enphase Energy Launches IQ9N Microinverters with GaN Technology for U.S. Residential Solar
IQ9N Microinverters support 16 A of continuous DC current and 427
GaN technology enables a peak efficiency of up to 97.8%, with cooler operation and optimized performance across conditions. Enphase’s GaN architecture reduces conduction losses and heat, improves long-term reliability based on engineering and lifecycle testing, maintains peak performance across seasons, and provides capacity to support emerging high-power solar panels.

"Every hour our crew spends on a roof — and every time we have to go back — cuts into our margins," said
"IQ9N Microinverters are a major leap forward in residential inverter performance," said
IQ9N Microinverters are engineered to optimize energy from every panel across a wide range of conditions, including partial shading, complex roof layouts, and high-temperature environments. Like all Enphase microinverters, IQ9N Microinverters convert DC to AC at each panel, eliminating long high-voltage DC runs used in traditional string inverter designs and delivering a safer, all-AC architecture on the roof. Per-panel power conversion also keeps the rest of the system producing even if one panel is shaded, soiled, or offline.
"Enphase keeps setting the bar higher," said
"Homeowners want solar that just works, year after year, in any weather," said
IQ9N Microinverters meet rigorous grid compliance standards and are NEMA Type 6 rated with a double-insulated, corrosion-resistant polymer housing and an operating temperature range of -40°C to +65°C, engineered to withstand extreme weather conditions. Built-in rapid shutdown capability helps reduce risk to utility workers and first responders. Homeowners can monitor system performance at the panel level, receive real-time alerts, and benefit from over-the-air software updates through the Enphase® App.
