Zigbee Wired USB Extender
installation guide
Wired USB Extenders relocate the Communications kit away from IQ Gateway. If there is a
large distance between the IQ Gateway and IQ System Controller/IQ Batteries or if there
are obstructions like concrete walls between them, then a Wired USB Extender should be
used to move the Communications kit near the IQ System Controller/ IQ Batteries.
A Range Test can determine if a Wired USB Extender is required.
Zigbee Range Test user manual, and the Designing an Enphase Zigbee network
tech brief describe how to conduct a Range Test, choose optimal location for the
equipment, and select a range extension method. Please follow the guidelines in
the above documents to determine if a Wired USB Extender is needed. The Zigbee
range extension FAQ has answers to specic questions that installers may have.
Preparations to be done before installation
1. Purchase an o-the-shelf CAT5e/CAT6 or Fiber based USB extender that contains
a transmitter, a receiver, USB cable, and power adaptor. Ensure that the extender
meets regulatory requirements in your region.
2. The USB port on the IQ Gateway where the extender must be plugged is of USB
Type-A. Therefore, ensure that the cable that comes along with the extender kit is
also of USB Type-A.
3. Purchase an o-the-shelf, half-duplex or full duplex ber/ethernet cable, and
choose the length based on the distance required. If the ethernet cable
is passed in the same conduit as power lines, please make sure that the
cable is shielded.
4. Make sure there is a power socket near the nal location of the Communications kit
for powering the USB over ethernet transmitter. The power socket must be
on a backed-up circuit.
5. Complete the installation of the Wired USB Extender before commissioning the
Enphase system using the Enphase Installer App.
6. If you plan to remove the IQ Combiner dead-front cover, make sure that the
IQ Combiner is de-energized.
