Enphase IQ8P-3P 480VA Three-Phase Microinverter

About This Product

The Enphase IQ8P-3P 480VA Three-Phase Microinverter is a module-level solar microinverter designed for grid-connected photovoltaic systems using 208V three-phase electrical service. Part of the Enphase IQ8 Series, this model converts DC electricity from an individual solar panel into grid-compatible AC power directly at the module.

The IQ8P-3P-72-E-US is designed for use with compatible 72-cell PV modules and provides 475W rated continuous AC output with a 480VA peak output rating. It features MC4 DC connectors and a four-pin EN4 bulkhead connector for the AC connection. Its distributed architecture supports individual panel power conversion and module-level monitoring when integrated with compatible Enphase system equipment.

Who This Product Suits

The Enphase IQ8P-3P is suited to US solar installers designing commercial and other grid-connected PV systems with 208V three-phase electrical service. It is particularly useful where module-level power conversion, individual panel monitoring, and flexible array layouts are required.

This microinverter is appropriate for installations using electrically compatible 72-cell solar modules and Enphase three-phase system components. Installers should confirm PV module electrical compatibility, AC branch circuit requirements, Enphase equipment compatibility, and applicable NEC requirements before specifying the system.
