Enphase IQ8AC (IQ8AC-72-M-INT)

The micro‑inverter enables grid‑compliant conversion of DC power from individual PV modules and is designed for modules with higher currents and modern cell architectures. The compact design, integrated MC4 connectors, and high efficiency support reliable, modularly scalable system design.

• TechnologyThe micro‑inverter is based on a transformerless power topology and, with a maximum AC output of 360VA and a DC input voltage range up to 60V, provides efficient power conversion per module. The high efficiency of up to 97.5% improves energy yield, especially under changing irradiation conditions.
  
  Power topology & efficiency
  • Transformerless architecture to reduce conversion losses and increase operating efficiency across different module voltages.
  • High efficiency of up to 97.5%, minimizing yield losses at partial load points.
  • Integrated MC4 connectors for clean, low‑loss DC connection at the module.
