Technical Data. enphase Envoy-S Standard, Envoy-S Metered

Below you will find brief information for Envoy-S Standard, Envoy-S Metered. The Envoy-S operates as a gateway between the Enphase Microinverters and Enphase Enlighten. The Enphase Enlighten web-based monitoring and analysis software analyzes the data collected by each communicating microinverter. Enlighten automatically detects any shortfall in energy production, identifies possible causes, and suggests solutions.
