Zigbee Wireless Range
Extender installation guide
Model number: COMMS-24-EXT-01 and COMMS-24-EXT-INT-01
The Zigbee Wireless Range Extender ((COMMS-24-EXT-01 for NA or COMMS-24-EXTINT-01 for EMEA)) may be required when Enphase IQ Batteries™ or the IQ System Controller
are located far from the IQ Gateway (IQ Combiner or a stand-alone IQ Gateway).
The IQ Gateway, IQ System Controller, and IQ Battery communicate with each other using
the 2.4GHz wireless band. Range extension is needed in cases where the RF signal quality
between them is inadequate. This could either be due to a weak signal and/or the presence
of RF noise at the site. A Range Test (refer to Zigbee Range Test user manual) can determine
the need and location of the Zigbee Wireless Range Extender.
INSTALLATIONGUIDE
If IQ Gateway and IQ System Controller are co-located, and IQ Batteries devices are placed
at a location that is not in the line of sight with them, then the preferred option should be to
place the Zigbee Wireless Range Extender at a location where it is in line of sight with both
sets of devices. Alternatively, the Zigbee Wireless Range Extender should be placed at a
location midway between the devices.
A Range Test must be conducted again after nalizing an appropriate location for the
Zigbee Wireless Range Extender. Direct links between the Zigbee Wireless Range Extender
and IQ Gateway, IQ System Controller, and IQ Batteries respectively must pass Range
Test. In case Zigbee Wireless Range Extender does not pass the Range Test, Wired USB
Extender must be considered. Please refer to the Zigbee range extension FAQ for further
recommendations.
To use the Zigbee Wireless Range Extender, you must purchase an o-the-shelf 5V DC USB
adaptor and a suitable NEMA 3R enclosure to house the extender if it is placed outdoors. All
installations must comply with national and local electrical codes. Professional installation
is recommended.

A) Purchase an o-the-shelf USB adaptor (Output-5VDC, 200mA, 1W power) and a suitable
NEMA 3R enclosure for the wireless range extender if placed outdoors. Visit the Enphase
Support webpage for recommendations on the USB adaptor and the type of enclosure
that can be used.
B) Make sure there is a power socket nearby to plug in the extender. The socket must be
powered from a circuit that is backed-up.
C) Use the Enphase Installer App to commission the Range Extender
• Download the latest version of Enphase Installer App from the iOS App Store or Android
Play Store. You may also download it from the Enphase website at enphase.com/tool
• Log into the Enphase Installer App on your mobile
D) You must upgrade the IQ Gateway software to version 7.0.69 or later for Ensemble 1.0/1.5
and 7.0.102 or later for Ensemble 2.0 for the COMMS-24-EXT-01 in NA and software version
7.2.20 or higher for COMMS-24-EXT-INT-01 in EMEA.
• Download the latest version of IQ Gateway software by going to the Settings tab in the
Installer App and using the Update Now button under IQ Gateway software.
NOTE: The IQ Controller software update process may take up to 25 minutes. During the software update, the LEDs on the IQ Controller ash green
one at a time from right to left. During this time the IQ Controller will reboot multiple times. All four LEDs ash red when the IQ Controller reboots.

Step 1: Tap on Systems in the Enphase Installer App → Select the system you are working
with or tap [+] to add a system. Make sure system details are added as part of Step 1.
Step 2: Devices and Array: Enter 1 for the number of Range Extenders in the system. Scan
the QR code on the Zigbee Wireless Range Extender using camera scanner to get the serial
number or manually enter the serial number.
Step 3: Connect to the IQ Gateway with your mobile device (smart phone or tablet). On the
IQ Gateway if the AP mode LED is not lit, press the AP mode button. The AP mode LED lights
as solid green when the WiFi network created by IQ Gateway is available
• On your mobile device, go to Settings and join the WiFi network “Envoy_nnnnnn”
(where “nnnnnn” equals the nal six digits of the IQ Gateway serial number).
Step 4: Go to the InstallerApp and make sure your mobile device is connected to IQ
Gateway. Proceed to Provision devices.
Step 5: During Provisioning of devices, with your mobile device in hand, walk from the IQ
Gateway toward the Zigbee Wireless Range Extender. This helps to ensure that the Zigbee
Wireless Range Extender can be provisioned over Bluetooth Low Energy (BLE).
• Initially the Installer App shows the Range Extender as Not Discovered while the circle
next to it spins indicating that Installer App is trying to discover it using Bluetooth.
• Wait near the Range Extender until the Installer App shows “Waiting for Provisioning”.
• Return to the IQ Gateway. The status is now shown as “Waiting for Acknowledgment”.
Enphase Installer App is waiting for IQ Gateway to conrm communication with the
Extender.
• Wait until it shows as Provisioned. The Zigbee network is now ready.
