Enphase IQ8AC 366VA Single-Phase Microinverter

About This Product

The Enphase IQ8AC 366VA Single-Phase Microinverter is a module-level inverter designed to convert DC power from an individual solar panel into grid-compatible AC power. Manufacturer model IQ8AC-72-M-US provides up to 366 VA peak output at 240 VAC and uses MC4 DC connectors. It is part of the Enphase IQ8 Series and is designed for use within compatible Enphase solar energy systems.

Who This Product Suits

The Enphase IQ8AC suits residential and light commercial solar installations where module-level power conversion, individual-panel operation, and the Enphase system architecture are specified. It is commonly paired with PV modules in the 295-500 W range, subject to the module meeting Enphase input-voltage and current requirements. It is particularly useful for systems where installers want a distributed microinverter design rather than a conventional centralized string inverter.

Specifications Explained

• Peak AC output: 366 VA at 240 VAC and 350 VA at 208 VAC.
• Continuous AC output: Up to 349 VA at 240 VAC.
• PV module pairing: Commonly used with modules rated from 295 W to 500 W, with final compatibility determined by module voltage and current specifications.
• MPPT range: 28-45 V, allowing the microinverter to track the connected module’s operating point independently.
• DC input: 60 V maximum input voltage, 14 A maximum continuous input current, and 20 A maximum permitted module short-circuit current.
• Efficiency: 97.3% peak efficiency and 97.0% CEC weighted efficiency at 240 VAC.
• Branch circuits: Up to 11 IQ8AC units per 20 A branch circuit at 240 VAC, subject to system design and applicable NEC requirements.
• Connection: This IQ8AC-72-M-US version is supplied with MC4 DC connectors.

Summary

The Enphase IQ8AC is a 366 VA microinverter for US Enphase solar installations using compatible higher-output PV modules. It combines module-level MPPT with 240 V or 208 V AC operation and integrates into the Enphase IQ system architecture. For installers specifying an IQ8 Series system, the IQ8AC-72-M-US provides a straightforward module-level conversion option with MC4 connectivity and a 25-year manufacturer warranty.
