Grid Interconnection Details
Enphase IQ7 series Microinverters are grid support interactive inverters.
Grid Profiles
IQ 7 series Microinverters have field-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 profile was not set up during
registration, the installer can set up the system to use an alternate Grid Profile (set of trip points).
NOTE: Only an authorized installer, following the requirements of the local electrical utility, is
allowed to make Grid Profile adjustments.
NOTE: Grid profile 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 profile management tasks include:
•
Set the grid profile for your region
•
View or verify current trip point settings
•
Generate a report for confirmation of site settings to the utility or other authority
To modify the grid profile or the parameters within the grid profile, installers must log in to their Enlighten
account using their credentials.
