Installing the IQ Gateway
To install the IQ Gateway, perform the following steps and refer to this diagram and the wiring
diagrams on the following pages:
LEDs and buttons
Terminal
block
USB
Ethernet port
ports
1. Choose a Location for the IQ Gateway
a.
Install the IQ Gateway near the switchboard. This ensures that the IQ Gateway receives the
strongest possible communications signal from each microinverter.
b.
The IQ Gateway-Must be installed so that the buttons are accessible.
c.
If you are installing the IQ Gateway in a three-phase application, the power line communication
signal must be
“coupled” between the three phases to allow the Envoy to communicate with all of
the microinverters in the system. Install a phase coupler on the load side of the over-current
protection device. See the Enphase Technical Brief on Phase Coupling for your region at
d.
Install the IQ Gateway in a protected dry space (such as a garage, attic, basement, or other
cool, dry location) and, if the IQ Gateway is hard-wired outdoors, you must also install it inside
an IP54- rated, or better enclosure with conduit attachment. Use an appropriately rated
enclosure if hard- wiring indoors.
NOTE
: Metallic enclosures may impair Wi-Fi signal strength.
e.
Mount the Envoy horizontally using the included DIN rail.
WARNING:
Risk of equipment damage. When installing the IQ Gateway in an enclosure,
choose area for installation where ambient temperature does not exceed 46º C.
f.
To
wall-mount
use two appropriately sized screws and a screwdriver. Mount the DIN rail first,
and then clip the IQ Gateway to the DIN rail.
