Step 10: Energize The System; Set Up And Activate Monitoring - enphase IQ8AC Installation And Operation Manual

Step 10: Energize the system

A. Turn ON the AC disconnect or circuit breaker for the branch circuit.
B. Your system will ramp up to full producing power after grid profile propagation and device
provisioning are completed. It may take 20-30 minutes for full power production based on the
number of microinverters in the system.
C. Check the LED on the connector side of the microinverter:
LED colour
Flashing green
Flashing orange
Flashing red
Solid red
Refer to the IQ Gateway Quick Install Guide
management functions.

4.1 Set up and activate monitoring

Refer to the IQ Gateway Quick Install Guide to install the gateway and set up system monitoring and grid
management functions. This guide leads you through the following:
•
Connecting the gateway
•
Detecting devices
•
Connecting to Enphase Installer Platform
•
Registering the system
•
Building the virtual array
NOTE: When the electricity network operator requires a grid profile other than the profile set on
the microinverter, you must select an appropriate grid profile for your installation. Your system
will ramp up to full power after grid profile propagation and device provisioning is completed. It
may take 20-30 minutes for full power production based on the number of microinverters in the
system.
You can set the grid profile through Enphase Installer Platform, during system registration, or through
Enphase Installer App at any time. You must have an IQ Gateway to set or change the grid profile. For more
information on setting or changing the grid profile, refer to the IQ Gateway Installation and Operation
Manual at https:/ /enphase.com/en-gb/installers/resources/documentation

IQ8MC/IQ8AC/IQ8HC Installation and Operation Manual
Normal operation. AC grid function is normal, and there is communication
with the IQ Gateway. IQ8 Series Microinverter's LED will be flashing green
only after provisioning.
The AC grid is normal but there is no communication with the IQ Gateway.
The AC grid is either not present or not within the specification.
There is an active DC Resistance Low, Power Off condition. To reset, refer to
the IQ Gateway Installation and Operation Manual at:
https:/ /enphase.com/en-gb/installers/resources/documentation.
If the problem persists, measure resistance between PV+ to EARTH and then
PV- to EARTH on the PV module and then inverter. Anything less than ~7 kΩ
will trigger the DC Resistance Low, Power Off condition. Usually, the value is
in MΩ on the inverter or PV module. Swap out faulty PV module or
microinverter.
