Set Up and Activate Monitoring

Refer to the Enphase IQ Envoy Quick Install Guide to install the IQ Envoy and set up system monitoring

and grid management functions. This guide leads you through the following:

• Connecting the Envoy

• Detect devices

• Connecting to Enlighten

• Registering the system

• Building the virtual array

NOTE: When the utility requires a profile other than the default IEEE 1547 (for example

grids managed by Hawaii Electric Industries [HEI] including HECO) you must select an

appropriate grid profile for your installation. You can set the grid profile through

Enlighten, during system registration, or through Installer Toolkit at any time. You must have

an Enphase Envoy communications gateway to set or change the grid profile. For more

information on setting or changing the grid profile, refer to the Enphase IQ Envoy Installation

and Operation Manual at enphase.com/support.
