About This Product

The Enphase IQ9N Microinverter 427 VA Peak Power MC4 DC Bulkhead is a module-level solar microinverter designed for modern high-output PV panels. It converts DC power from an individual solar module into grid-compatible AC power directly at the panel, allowing each module to operate independently. The IQ9N provides up to 427 VA continuous AC output and uses integrated Stäubli MC4 DC connectors for straightforward connection to compatible solar modules.

Who This Product Suits

This microinverter suits residential rooftop solar systems where module-level conversion, monitoring and independent panel operation are required. It is particularly suitable for higher-power PV modules and installations where different roof orientations, partial shading or future system expansion may make individual module control useful. It can also be used when expanding compatible existing Enphase IQ7 or IQ8 systems, subject to correct system design and Enphase compatibility requirements.

Specifications Explained

• Maximum continuous AC output: 427 VA, providing a higher module-level output capacity for modern solar panels.
• Maximum continuous DC input current: 16 A, allowing compatibility with many current high-current PV modules.
• Operating DC voltage range: 18 V to 58 V.
• MPPT: Individual maximum power point tracking allows each connected panel to operate independently rather than being controlled by a common string inverter MPPT.
• Peak efficiency: Up to 97.95% for efficient DC-to-AC conversion.
• DC connection: Integrated Stäubli MC4 connectors provide a standardised connection to compatible PV module leads.
• Communications: Uses Enphase power line communication for system monitoring and control through compatible Enphase equipment.
• Safety: Module-level conversion keeps the rooftop DC voltage low and supports rapid shutdown functionality as part of a correctly designed Enphase system.

Summary

The Enphase IQ9N is a 427 VA microinverter intended for modern residential solar installations using higher-output PV modules. Its 16 A continuous DC input capability, individual module MPPT, integrated MC4 connections and Enphase system compatibility make it a practical option for installers building or expanding an Enphase-based rooftop solar system.
