The Iq Gateway; How The Enphase Home Energy System Works - enphase Envoy-S Installation And Operation Manual

IQ Gateway Metered Installation and Operation

The IQ Gateway

The IQ Gateway is an integral component of the Enphase Home Energy Solution. It operates
between Enphase Microinverters, or other PV system, and the Enphase Installer App™ web-based
monitoring and analysis software. When used with Enphase devices, the IQ Gateway 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 it does not control grid
management functions.
The IQ Gateway Metered uses precision Current Transformers (CTs) to measure PV production from
the solar main supply switch and home energy consumption from the AC mains.

How the Enphase Home Energy System Works

This integrated system maximises energy harvest, increases system reliability, and simplifies design,
installation, and management.
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 maximises energy production by using a
sophisticated Maximum Power Point Tracking (MPPT) algorithm.
The IQ Gateway operates as a gateway between the Enphase Microinverters and Enphase Installer
App. It collects energy and performance data from the PV system over on-site AC power lines, and it
forwards that data to Enphase Installer App, via the Internet, for statistical reporting. Enphase
Installer App analyzes the data collected by each communicating device. Enphase Installer App
automatically detects any shortfall in energy production, identifies possible causes, and suggests
solutions. Enphase Installer App constantly monitors every Enphase device connected to the IQ
Gateway and is essential for system monitoring and troubleshooting.
Enphase Installer App provides a wide range of information on system performance. You can access
Enphase Installer App on your computer or mobile device and view current performance information
at any time.
