Wireless Range Extenders and the  
Enphase Microinverter System  
The Envoy with Wireless Adapter 
The Envoy Communications Gateway
TM
 is now available with a 
wireless adapter for sites using a wireless router. 
The Enphase Wireless Adapter (Wi-Fi USB stick), included with 
the Envoy model ENV-120-02, allows the Envoy to transmit 
Enphase

 Microinverter System
TM
 data through the on-site 
wireless network to the Enlighten
®
 Monitoring platform. 
Using the wireless adapter simplifies Envoy installation and 
reduces system commissioning time. 
With the Enphase wireless adapter, you can connect the Envoy to 
the Internet in one of two ways. 
•  Use the Wi-Fi WPS button on the wireless router. 
•  Configure the Envoy manually using the Envoy local interface. 
Refer to the Envoy Installation and Operations Manual for complete and detailed installation steps. 
Some installation sites require that you extend the range of the existing Wi-Fi network so that the Envoy 
with the wireless adapter can connect to the Internet. 
About Wireless Range Extenders  
In some situations, the wireless network on site may not have a range great enough for the Envoy to 
establish communications. Using wireless range extenders at these sites may strengthen the signal of the 
existing wireless network to allow Envoy connection to the Internet. 
This technical brief lists some wireless range extenders that, in Enphase’s experience, will likely extend 
the range of your existing wireless network to provide robust and reliable wireless communications. This 
list is not comprehensive and other range extenders may also work.
