emu communication gateway - enphse

The Enphase Envoy (EMU) is a communications gateway that collects performance information for each solar module in a user's system and transmits this data to the Enlighten™ website, where users can view and manage the performance of their solar power system.

Plug and Play:-

>_The Envoy can be plugged into any standard AC outlet.
>_Enphase Microinverters transmit data over the existing power line.
>_No additional wiring is required.
>_Once the unit is plugged into an AC outlet, simply connect an Ethernet cable from the Envoy into a broadband router.
>_Performance data is transmitted using broadband Ethernet protocols for immediate access to performance information.
>_The Enphase Envoy works in conjunction with the Enphase Microinverter and the Enlighten website.

The Enlighten website provides a wide range of information on the performance of solar power systems and individual solar modules. A graphical representation of the solar array provides "at a glance" information on the status of each module. More detailed information, including current and lifetime performance metrics, gives users a true view of the benefits of their solar energy installation. In addition, Enlighten provides access to mobile devices, allowing system owners to view real-time performance information anywhere, anytime.

Integrated Per-module Monitoring:-

Enlighten automatically monitors the performance of every module in the system. No additional monitoring hardware or software is needed. Unlike third party monitoring systems, which only monitor the inverter, Enlighten provides unprecedented visibility into the performance of every individual module.

Flexible Views:-

The Enlighten website provides harvest information in various forms - including summary views, totals by day/week/month/life-time, and time-lapse motion summary - for the entire array and individual modules. This richness of data collected from each module helps the owner troubleshoot and verify the solar system performance.


Enlighten is continuously monitoring the performance of the solar power system and will highlight any deviation in performance by comparing the harvest of individual modules to the harvest of surrounding modules. Customers can choose to be sent an alert upon certain conditions, and problems can be addressed either during routine maintenance or at the installer's convenience.

The Enphase Enlighten website works in conjunction with the Enphase Microinverter and the Enphase Envoy.

Environ Smart Thermostat:-

Environ is a smart thermostat device that integrates with the Enphase Enlighten™ website, allowing owners to simultaneously manage their solar system along with their heating and cooling system in a single web-based platform.


Heating and cooling typically account for over 50% of home energy use, adding up to hundreds of dollars every year. Environ makes it easy to take control of your energy usage with web-based thermostat controls.

Environ owners can set or adjust their home temperature at anytime and from anywhere, using a web browser or smart phone, as well as directly with the thermostat device.

How It Works:-

Environ wirelessly connects to the Envoy Communications Gateway using the Zigbee communications protocol. The Envoy connects the Environ to the internet, allowing it to transmit and receive information from the Enlighten website.

Environ Features:-

>_Controls nearly any common residential heating and cooling system,
>_Supports 3 stages of heat, 2 stages of cool, multi-stage heat pumps, humidifier, de-humidifier and external air baffles,
>_Programmable up to 7 periods per day, 7 days a week,
>_Large LCD touch-screen display,


>_Installed using standard thermostat wiring and mounting,
>_Zigbee wireless technology offers plug-and-play connectivity to the Envoy Communications Gateway,
>_Easily programmed using web browser interface,
