Enphase IQ8MC 330VA Microinverter

About This Product

The Enphase IQ8MC 330VA Microinverter is an IQ8 Series module-level inverter designed for residential grid-connected solar systems in the US. Model IQ8MC-72-M-US-NFC provides up to 330 VA peak AC output and is designed to work with modern higher-current PV modules. It converts DC power from an individual solar panel into grid-compatible AC power directly at the module and is supplied with integrated MC4 connectors for the DC connection. The IQ8MC operates as part of the Enphase Energy System and integrates with Enphase IQ Gateway monitoring and compatible Enphase system components.

Who This Product Suits

The Enphase IQ8MC is suited to residential installers building or expanding module-level Enphase solar systems where individual panel conversion, monitoring and flexible array design are required. It is particularly useful on roofs with multiple orientations, partial shading or layouts where conventional string design can be restrictive. The IQ8MC supports 240 V split-phase applications as well as compatible 208 V applications and should be paired with a PV module that falls within Enphase’s published electrical compatibility limits. Final system design, branch-circuit sizing and installation should follow Enphase instructions, applicable utility requirements and the NEC.

Specifications Explained

• 330 VA peak output: The IQ8MC delivers up to 330 VA peak AC output, with 320 VA maximum continuous output at 240 V.
• 240 V split-phase support: Designed for the common 240 V residential split-phase electrical service used in the United States, with support for compatible 208 V applications.
• 14 A continuous DC input: Higher input-current capability helps the IQ8MC pair with newer high-current PV modules, subject to Enphase module compatibility requirements.
• 25-45 V MPPT range: The maximum power point tracking range is designed to capture usable output from compatible PV modules across changing operating conditions.
• 60 V maximum DC input: Module voltage must remain within the inverter’s published input limits under expected site temperatures and operating conditions.
• Integrated MC4 connectors: The DC side uses integrated MC4 connections for straightforward pairing with compatible solar modules.
• 97.0% CEC weighted efficiency: The IQ8MC is engineered for efficient module-level DC-to-AC power conversion at 240 V.
• Rapid shutdown: IQ8 Series Microinverters are UL listed as PV rapid shutdown equipment when installed in accordance with Enphase requirements.
• 25-year limited warranty: Enphase provides long-term manufacturer warranty coverage subject to its applicable warranty terms and conditions.

Summary

The Enphase IQ8MC is a 330 VA IQ8 Series microinverter for US residential solar installations. Its 14 A continuous DC input capability, 25-45 V MPPT range, integrated MC4 connections and module-level architecture make it a practical match for many current-generation PV modules. For installers already working with the Enphase ecosystem, it provides a straightforward path to module-level power conversion, monitoring and NEC-compliant system design when installed with the required compatible Enphase components.
