  • Page 6: The Enphase Envoy Communications Gateway

    Envoy Installation and Operation The Enphase Envoy Communications Gateway The Envoy® Communications Gateway is an integral component of the Enphase® 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 7: Other Elements In The Enphase System

    Envoy Installation and Operation Other Elements in the Enphase System The Enphase Microinverter converts the DC output of the PV module into grid-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.

  • Page 8: Envoy Installation

    Review the following preinstallation checks and sizing considerations before you install the Envoy. System Sizing The Envoy is capable of servicing a large system of Enphase Microinverters. This number varies with Envoy model. Check the model number (SKU) on the Envoy box, or on the back of the Envoy, to determine which model you are installing.
