    Envoy Installation and Operation The Enphase Envoy Communications Gateway The Envoy is an integral component of the Enphase Energy Microinverter system. It operates between the Enphase Microinverters and the Enphase Enlighten™ web-based monitoring and analysis software. The Envoy functions as a gateway and monitors the microinverters that are connected to the PV modules.

  • Page 6: Other Elements In The Enphase System

    Other Elements in the Enphase System The Enphase Microinverter is a fully integrated device that converts the DC output of the PV module into electric-utility compliant AC power. In addition to performing the DC to AC conversion, it maximizes the PV modules' energy production by using a sophisticated Maximum Power Point Tracking (MPPT) algorithm.
