Enphase Energy Brings Next-Gen Micro-Inverters To U.S. Market

Enphase Energy Inc., a solar micro-inverter and global energy technology company, has begun shipping the Enphase IQ Microinverter System, the sixth generation of Enphase micro-inverters.

“Enphase continues to be the innovation leader in solar with the delivery of our IQ Microinverter System, which dramatically simplifies the solar installation,” says Paul Nahi, president and CEO of Enphase. “Our IQ technology will also enable the introduction of Enphase Energized AC Modules, which will be the ultimate game-changer for the residential solar industry.”

Like previous generations of the technology, the Enphase IQ System is a complete AC solution that uses no high-voltage DC, providing the safest-possible solar solution for homeowners. The system is also designed and manufactured for reliability, assured by over 1 million hours of power-on testing.

Lighter and easier to install, IQ micro-inverters use a unique double-insulated, non-corroding polymeric enclosure that contributes to a design that is 30% lighter than Enphase S-Series micro-inverters. The new two-wire Q Cable that is part of the IQ Microinverter System uses half the copper and is 50% lighter than the previous generation of Enphase trunk cables.

IQ micro-inverters meet or exceed regulatory requirements set by the National Electrical Code (NEC) and individual states. For example, Enphase is certified compliant with NEC 2014 and 2017 rapid shutdown requirements. Unlike string inverters, this capability is built in, with no additional equipment necessary.

In addition, Enphase IQ micro-inverters comply with requirements for distributed solar on utility networks included in Rule 21 in California and Hawaiian Electric Co. Rule 14H, such as power factor, voltage and frequency ride-through requirements.

Addressing the growing market demand for high-powered modules, the Enphase IQ 6+ Micro supports both 60- and 72-cell modules up to 400 W DC and is now shipping in the U.S. The Enphase IQ 6 Micro, which pairs with modules up to 330 W DC, will become available in the U.S. this summer.

Also coming to market this summer, IQ micro-inverters will be integrated into Enphase Energized AC Modules with IQ from LG, SolarWorld and Jinko Solar. AC modules will further simplify residential solar installations by streamlining the supply chain, reducing capital costs, and expediting the design and installation processes.
