Envoy features:

  • Plug & Play setup
  • Installation flexibility in connecting to a router
  • Communicates over existing electrical wires
  • Enables remote troubleshooting of solar array
  • Connects up to 600 microinverters
  • Bi-directional communications let Envoy adapt to future utility requirements.

Enlighten monitoring service features:

  • See individual panel performance, not just the inverter.
  • Receive alerts when the system or individual panels are not performing as expected.
  • With at-a-glance views of energy production and performance, system owners can see their system is performing as expected.
  • Easily compare current performance against a previous day week or month.
  • View historical weather data to understand variations in performance.
  • System status indicator tells you when the system is not performing as expected and what can be done to restore performance.
  • One-click sharing with integrated social media buttons. Accessible from any device with an Internet connection.
Envoy Internet Connectivity Options
Connection Description Which accessory do I need?

Ethernet cable
Connect to your Internet router via a standard Ethernet cable. Limited by cable length. (None; included with this item)

Connect to your existing wireless network (standard 802.11b/g/n Wi-Fi) Enphase WF-01 - Wi-Fi Adapter for Envoy (#2977070)

Powerline network
Create a network through your home's existing electrical wiring. Not wireless, but requires no additional wiring and still works across rooms. (Wikipedia: Powerline networking) Enphase EPLC-01 - Power Line Carrier for Envoy (#9937525)

ZigBee is a specialized wireless technology used ONLY for particular products that require it, such as the GE i210 Revenue Grade Meter (RGM). (Wikipedia: ZigBee)

Please do not choose this option unless another product you're using specifically tells you to. "Regular" wireless networks use the WF-01 Wi-Fi Adapter instead (above).

About Enphase

Enphase Energy delivers microinverter technology for the solar industry that increases energy production, simplifies design and installation, improves system uptime and reliability, reduces fire safety risk and provides a platform for intelligent energy management. Our semiconductor-based microinverter system converts energy at the individual solar module level and brings a systems-based, high technology approach to solar energy generation. Enphase Energy is committed to quality, reliability, and environmental responsibility, and is ISO 9001:2008 and ISO 14001:2009 certified. Their commitment is expressed in every design they test, every component they select, every product they manufacture, and every system they monitor. The result is that their fourth-generation system reflects what they believe are the industry's most rigorous standards, only coming to market after one million hours of power-on testing.

Ease of Design and Installation
Solar electric systems using Enphase Micro-Inverters are simple to design and simple to install:

  • There are no string calculations necessary
  • Individual solar panels may be installed in any combination of module quantity, type, orientation and age.
  • Each micro-inverter quickly mounts on the solar panel racking, directly beneath each panel.
  • Low voltage DC wires connect from the solar panel directly to the co-located micro-inverter, eliminating the risk of the installer's exposure to lethal 600VDC power.

Enphase Supports a Great Online Monitoring System called Enphase Enlighten
By registering for Enphase Enlighten, a web-based monitoring and analytics system, you can monitor each solar panel in your array from anywhere you have internet access. The Enlighten website provides a wide range of information on your system and the individual solar panels. A graph of the solar array provides info on each module, including current and lifetime performance.

Enphase Micro-Inverters Maximize Power Output
With the Enphase Micro-Inverters, if one of your solar panels is shaded, or damaged, it does not affect the output of the rest of your solar array. All panels perform to their greatest capacity.

Each Solar Module has its own Enphase Inverter
An individual Maximum Peak Power Point Tracking Controller (MPPT) controls the output of each solar panel.  This insures that the most available power from each panel flows into your system, regardless of the performance of the rest of the panels in the array.

The Micro-Inverter concept insures that there is no single point of failure in your solar electric system.  Enphase Micro-Inverters are designed to operate at full power at temperatures as high as 65 degrees C (150 degrees F).
