Installation Planning And Preparation - enphase Envoy-S Installation And Operation Manual

Installation Planning and Preparation

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 Installer App monitoring and
analysis website. The IQ Gateway communicates with the Enphase Microinverters and AC Batteries
using the site's power lines.
After the IQ Gateway is installed and all devices (microinverters and/or batteries) are scanned or
provisioned, the IQ Gateway maintains an internal database of all known Enphase devices at the
site it manages. At regular intervals, the IQ Gateway polls each Enphase device for its energy data.
Using its Internet connection, the IQ Gateway then forwards that information to Enphase Installer App.
The IQ Gateway also reports any error conditions affecting itself or other Enphase devices. You can
view both energy data and error conditions in Enphase Installer App.
The IQ Gateway incorporates power line and Internet communications functions. One "side" of the IQ
Gateway communicates with the Enphase devices through power lines at the site. The other "side" of the IQ
Gateway communicates with Enphase Installer App over the Internet.
