Installing with Enphase

The rooftop work for an Enphase system follows an easy, step-by-step process. Use the overview below as your guide or dig into the details in each of the sections that follow.

  1. Position the Enphase AC cabling
  2. Install an AC branch circuit junction box / isolator
  3. Attach the microinverters to the PV racking
  4. Create a paper installation map
  5. Ground the microinverters (if required)
  6. Dress the Enphase cabling
  7. Connect the microinverters to the Enphase cabling
  8. Terminate the unused end of the Enphase cabling and seal any unused cable connections
  9. Connect the Enphase cabling to the AC branch circuit junction box
  10. Connect the PV Modules to the microinverters

After you’ve completed the rooftop work, you’ll complete electrical work on the ground and you'll install the Envoy. Then you’ll energize the system and complete commissioning using the Installer Toolkit mobile app.

System Compatibility

The IQ System uses the 2-wire Q-Cable and a new line-to-line power line communications protocol. When using the IQ Micros take care to use only the IQ Envoy and Q Accessories. Double-check to ensure that the component part number on the box includes “Q” or “IQ”. The IQ System is not compatible with our previous systems.

Communications and Control (Envoy)

The Envoy is the monitoring and control appliance for the system, and it communicates with system components over the AC power lines at the site and with Enlighten over an Internet connection.

Successful installation and commissioning of the Envoy means that power line communications are good and the Envoy is reporting to Enlighten.

If the Envoy is unable to communicate with system components, operations may be impaired. If the Envoy is not connected to the Internet, the homeowner will be unable to monitor their system in Enlighten, and you won't be able to perform remote operations and maintenance.

The sections below cover the physical installation of the Envoy. On our Commissioning page, we'll step you through configuring your Envoy and how to connect it to the Internet.
