The Enphase IQ Envoy
The Enphase IQ Envoy is an integral component of the Enphase Home Energy Solution. It operates between
the Enphase devices, or other PV system, and the Enphase Enlighten™ web-based monitoring and analysis
software. When used with Enphase devices, the IQ Envoy can control grid management functions and
monitor PV production and site consumption. When used with non-Enphase PV systems, it can collect
production and consumption data, but does not control grid management functions.
IMPORTANT: Enphase IQ Envoy and IQ 6 and IQ 6+ Micros do not communicate with, and should not be
used with, previous generation Enphase Microinverters and Envoys. Always use IQ 6 and/or IQ6+
Microinverters with an IQ Envoy.
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 IQ Envoy operates as a gateway between the Enphase devices and Enlighten, using precision Current
Transformers (CTs) to measure PV production and home energy consumption. It collects energy and
performance data from the PV system over on-site AC power lines, and it forwards that data to Enlighten, via
the Internet, for statistical reporting. Enlighten analyzes the data collected by each Enphase device
connected to the IQ Envoy. Essential for system monitoring and troubleshooting, Enlighten automatically
detects any shortfall in energy production, identifies possible causes, and suggests solutions.
Enlighten provides a wide range of information on system performance. You can access Enlighten on your
computer or mobile device and view current performance information at any time.
