Pre-installation Checks
Review the following pre-installation checks before you install the Envoy-S:
Download the Installer Toolkit App
The Enphase Installer Toolkit is a mobile app for iOS and Android devices (smart
phone or tablet) that allows installers to configure the system while onsite,
eliminating the need for a laptop and improving installation efficiency.
Download the latest version of the Enphase Installer Toolkit mobile app
and open it to log in to your Enlighten account. With this app, you can
connect to the Envoy to track system installation progress. Go
to enphase.com/installer-toolkit or scan the QR code:
To run the Installer Toolkit app, you need either of the following
mobile devices:
- An Android mobile device running Android version 5
(Lollipop) or later, or
- An iOS device running iOS 8.0 or later, specifically an iPhone 4 or
later or an iPod Touch 5th generation

Enphase Envoy-S Quick Install Guide
Plan the Enclosure Type
Install the Envoy-S in an IP54-rated, or better enclosure. Use an appropriately rated enclosure if hard-
wiring indoors.
Use a Phase Coupler for a Multiphase Site
If you are installing in a multiphase application, the power line communication signal must be “coupled”
between the phases to allow the Envoy to communicate with all of the Enphase devices in the system.
Install a phase coupler on the load side of the over-current protection device. See the Enphase Technical
Brief on Phase Coupling for your region at enphase.com/support or consult Enphase support for
compatible devices.
Plan the Internet Connection
To use the Enlighten web-based monitoring and analysis software, additional requirements are:
Internet connection for the Envoy-S through a traditional router or modem or Enphase Mobile
Connect (Enphase model CELLMODEM-02). Decide whether to connect the Envoy-S to the
Internet using integrated Wi-Fi, an Enphase Mobile Connect modem, or using a PLC bridge with
Ethernet cables.
