The Enphase Envoy-S
The Enphase Envoy-S 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-S monitors the microinverters that are connected to the PV modules. It collects energy
and performance data from the microinverters over on-site AC power lines, and it forwards that data to
Enlighten, via the Internet, for statistical reporting.
How the Enphase Microinverter System Works
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 energy production by using a sophisticated
Maximum Power Point Tracking (MPPT) algorithm. This integrated system maximizes energy harvest,
increases system reliability, and simplifies design, installation and management.
The Envoy-S operates as a gateway between the Enphase Microinverters and 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. Enlighten constantly monitors every Enphase Microinverter connected to the Envoy-
S and is essential for system monitoring and troubleshooting.
Enlighten provides a wide range of information on system performance. You can even access Enlighten on
your mobile device and view current performance information wherever you are.
