  • Page 6: The Enphase Envoy Communications Gateway

    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. The Envoy collects energy and performance data from the microinverters over on-site AC power lines.

  • Page 7: Other Elements In The Enphase System

    Installation and operation of the Envoy require no specialized equipment or unique computer or networking expertise. To the Local Area Network (LAN), the Envoy is just another host on the network, much like a personal computer. The Envoy simply connects to the on-site router for communications with the Enphase Enlighten monitoring and analysis website.

  • Page 8: Installation Planning And Preparation

    The Envoy is capable of monitoring 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. Check the following table for capacity information:...
