must select an appropriate grid profile for your installation. You can set the grid profile through the
Enphase App, during system registration, or through the Enphase Installer App at any time. You must
have an Enphase IQ Gateway to set or change the grid profile. For more information on setting or
changing the grid profile, refer to the Enphase IQ Gateway Metered Installation and Operation
Manual at enphase.com/support.
