Enphase IQ8AC Microinverter

Enphase IQ8AC Microinverter

The Enphase IQ8AC is a microgrid-forming, software-defined microinverter with split-phase power conversion capability. Built on Enphase's proprietary ASIC with advanced 55nm technology, the IQ8AC enables operation in both grid-tied and off-grid modes with superfast response times to changing loads and grid events. Designed for mid-power solar modules rated 295-500W, it supports 54/108, 60/120, 66/132, and 72/144 half-cell PV modules.
