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