Learn about everything that goes into installing Enphase Energy Systems.

IQ Microinverters

Follow the simple step-by-step process to install Enphase IQ Microinverters and IQ Cables on the roof.

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

 

Once finished, you’ll complete electrical work on the ground and install the IQ Gateway. Then you’ll energize the system and complete commissioning using the Enphase Installer App.

Sunlight Backup

Learn about installing IQ8 Series Sunlight Backup systems and get all the technical briefs, data sheets, and installation guides.

Storage 

Learn about installing Enphase Energy systems with storage and get the technical documentation.

Communications and control

The IQ Gateway enables remote monitoring and control for Enphase Energy Systems. The IQ Gateway communicates with system components via AC power lines at the site and with the Enphase Installer Portal over an internet connection.

Your installation was successful if power line communication is good and the IQ Gateway is reporting to the Enphase Installer Portal. If the IQ Gateway is not communicating with system components, it may impair system operations. Remote monitoring and control will also be unavailable if the IQ Gateway is not connected to the internet.
