Installation Planning and Preparation
Installation and operation of the Envoy-S require no specialized 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 individual microinverters using the site’s power lines and in the Engage Cable.
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.
Pre-installation Checks
Review the following pre-installation checks before you install the Envoy-S.
Plan the Power Connection
Before installing the Envoy-S, make sure that the site has either a standard AC outlet available near the load
center or subpanel in which the Envoy-S can be hardwired. Do not use a power strip.
