Grid Interconnection Details

Both the Enphase IQ 7 and the IQ 7+ Microinverter are grid support interactive inverters. This type of inverter is also

known as a Grid Support Utility Interactive Inverter (GSUII). The IQ 7 and IQ 7+ also comply with California Rule 21 -

2016 and Hawaii Rule 14H - 2017.

Grid Proles

IQ 7 and IQ 7+ Microinverters have eld-adjustable voltage and frequency trip points. Trip points are input voltage

and frequency values that trigger the microinverters to shut down when the values are exceeded. If local regulations

require adjustments to these trip points, or if the grid prole was not set up during registration, the installer can set

up the system to use an alternate Grid Prole (set of trip points).

NOTE: Only an authorized installer, following the requirements of the local electrical utility, is allowed to make

Grid Prole adjustments.

NOTE: Grid prole changes are applied only after a microinverter is detected.

In some regions and in some situations, microinverter trip points may be adjusted to account for high grid voltage or

for local conditions.

Grid prole management tasks include:

y Set the grid prole for your region

y View or verify current trip point settings

y Generate a report for conrmation of site settings to the utility or other authority

To modify the grid prole or the parameters within the grid prole, installers must log in to their Enlighten account

using their credentials.

The following tables show the parameter settings for the grid proles available for North America:
