Step 10: Energize the system
A. Turn ON the AC disconnect or circuit breaker for the branch circuit.
B. Turn ON the main utility-grid AC circuit breaker. Your system starts producing power after
a five-minute wait time.
C. Check the LED on the connector side of the microinverter:
LED color
Flashing green
Normal operation. AC grid function is normal, and there is communication with the IQ Gateway.
Flashing orange
The AC grid is normal, but there is no communication with the IQ Gateway.
Flashing red
The AC grid is either not present or not within specification.
Solid red
There is an active "DC Resistance Low, Power Off Condition." To reset, see
– Power Off
3.1 Set up and activate monitoring
Refer to the IQ Gateway Quick Install Guide to install the IQ Gateway and set up system monitoring
and grid management functions. This guide leads you through the following:
•
Connecting the IQ Gateway
•
Detect devices
•
Connecting to Enphase Installer App
•
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 the
Enphase Installer App, during system registration, or through the Enphase Installer App at
any time. You must have an IQ Gateway communications 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 enphase.com/support.
