Enphase IQ8MC 330VA Microinverter

About This Product

The Enphase IQ8MC 330VA Microinverter is a module-level solar microinverter designed for use with compatible high-output PV modules in Enphase IQ8 solar systems. Model IQ8MC-72-M-US provides up to 330 VA peak AC output at 240 VAC and uses integrated MC4 bulkhead connectors for the DC module connection. Each microinverter independently converts the DC output of its connected solar module into grid-compatible AC power, providing module-level power conversion rather than relying on a central string inverter.

Who This Product Suits

The Enphase IQ8MC is suited to residential and light commercial Enphase installations using compatible PV modules and 240 V split-phase electrical service. It is commonly paired with modules in the 260 W to 460 W range, subject to the module’s voltage and current characteristics meeting Enphase compatibility requirements. Module-level conversion makes it particularly useful on roofs with multiple orientations, partial shading, or layouts where independent operation of each solar module is desirable. System design, branch-circuit sizing, rapid-shutdown requirements, and installation should follow Enphase documentation, applicable NEC requirements, and local utility rules.

Specifications Explained

The IQ8MC-72-M-US has a 330 VA peak output and 320 VA maximum continuous output at 240 VAC. Its DC operating range is 18 V to 58 V, with a 25 V to 45 V MPPT range and a maximum DC input voltage of 60 V. Maximum continuous DC operating current is 14 A, while maximum permitted module short-circuit current is 20 A. At 240 VAC, maximum continuous AC output current is 1.33 A and CEC weighted efficiency is 97.0%. The microinverter communicates through Enphase power-line communication and is designed as part of the wider Enphase IQ system.

Summary

The Enphase IQ8MC is a 330 VA peak-output microinverter for US Enphase solar installations. It combines module-level DC-to-AC conversion, integrated MC4 connectivity, a broad PV module compatibility range, and Enphase IQ system integration. For installers building an Enphase-based array with compatible higher-output modules, the IQ8MC provides a straightforward module-level inverter platform backed by Enphase’s 25-year limited warranty.
