Installation Planning and Preparation

Installation and operation of the IQ Gateway require no specialised equipment or unique computer or
networking expertise. To the Local Area Network (LAN), the IQ Gateway is just another host on the
network, much like a personal computer. The IQ Gateway simply connects to the on-site router or
Enphase Mobile Connect ™ (cellular modem) for communications with the Enphase Enlighten monitoring
and analysis website. The IQ Gateway communicates with the microinverters using the site's power lines.
After the IQ Gateway is installed and the microinverters are scanned or provisioned, it maintains an
internal database of all known Enphase Microinverters at the site it manages. At regular intervals, the IQ
Gateway polls each microinverter for its energy data. Using its Internet connection, the IQ Gateway then
forwards that information to Enlighten. The IQ Gateway also reports any error conditions that affect it or
the microinverters. You can view both energy data and error conditions in Enlighten.
The IQ Gateway incorporates power line and Internet communications functions. One "side" of the IQ
Gateway communicates with the microinverters through power lines at the site. The other "side" of the
IQ Gateway communicates with Enlighten over the Internet.
