The Enphase Envoy-S
The Enphase Envoy-S is an integral component of the Enphase Home Energy Solution. It operates between Enphase Microinverters, or other PV system, and the Enphase Enlighten™ web-based monitoring and analysis software. When used with Enphase devices, the Envoy-S can control grid management functions and monitor PV production and site consumption. When used with non-Enphase PV systems, it can collect production and consumption data, but it does not control grid management functions.
The Envoy-S Metered Multiphase uses precision Current Transformers (CTs) to measure PV production from the solar main supply switch and home energy consumption from the AC mains.
How the Enphase Home Energy System Works
This integrated system maximises energy harvest, increases system reliability, and simplifies design, installation and management.
The Enphase Microinverter converts the DC output of the PV module into grid-compliant AC power. In addition to performing the DC to AC conversion, it maximises energy production by using a sophisticated Maximum Power Point Tracking (MPPT) algorithm.
The Envoy-S operates as a gateway between the Enphase Microinverters and Enlighten. It collects energy and performance data from the PV system over on-site AC power lines, and it forwards that data to Enlighten, via the Internet, for statistical reporting. Enlighten analyzes the data collected by each communicating device. Enlighten automatically detects any shortfall in energy production, identifies possible causes, and suggests solutions. Enlighten constantly monitors every Enphase device connected to the Envoy-S and is essential for system monitoring and troubleshooting.
Enlighten provides a wide range of information on system performance. You can access Enlighten on your computer or mobile device and view current performance information at any time.

Installation Planning and Preparation
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 Enphase Microinverters and AC Batteries using the site’s power lines.
After the Envoy-S is installed and all devices (microinverters and/or batteries) are scanned or provisioned, the Envoy-S maintains an internal database of all known Enphase devices at the site it manages. At regular intervals, the Envoy-S polls each Enphase device 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 affecting itself or other Enphase devices. 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 Enphase devices 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:
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
Box Contents
Check the shipping box for the following items:
Enphase Envoy-S Metered Multiphase Current transformers (CTs): Two split core CTs, one for production and one for consumption
metering. You must order additional CTs (CT-100-SPLIT) to separately monitor multiple phases.
Length of DIN rail for mounting Ferrite bead to attach to your Ethernet Cable, if used 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 hard­wiring 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.

Metering CT Considerations
The Envoy-S uses readings from CTs to report measurement data for PV energy production and energy consumed by the home or business. When current transformers (CTs) are wrapped around a live wire, the current going through the wire induces a current on the CTs primary internal winding, which in turn induces a current on the CTs secondary internal winding. The current on the secondary winding is proportional to the current on the original circuit and this is used for making measurements. Install the CTs as shown in the wiring instruction for your region.
Production CTs measure power production through a connection to the solar supply main
switch.
Consumption CTs measure energy consumption through a connection to the AC mains.
To install the CTs, use a protected route in conduit for the CT wires to the Envoy-S. Install one split-core CT per monitored phase for production metering and one split-core CT per monitored phase for consumption metering. If you need to extend the CT leads (up to 148 meters), see “Extend CT Leads, If Needed” on page 16.
Required Items
If you hard-wire the Envoy-S outdoors, you must install it in an IP54-rated (or better) enclosure with conduit attachment. Note that Metallic enclosures may impair Wi-Fi signal strength. Use an
appropriately rated enclosure if hard-wiring indoors. Do not drill holes for conduit at the top of the enclosure or anywhere that allows moisture ingress.
The Envoy-S Metered Multiphase includes a production CT and a consumption CT. You must order additional CTs (CT-100-SPLIT) for multiphase installations. Make sure you have one CT for each phase monitored, for both production and consumption.
Optional Items
Make sure you have the following optional items, if needed:
Enphase Mobile Connect modem (order Enphase CELLMODEM-02) Ethernet over power line communication (PLC) bridge with Ethernet cables [order EPLC-02 (EU),
EPLC-03 (UK) or EPLC-04 (AU/NZ) separately]
Ethernet cable (use 802.3, unshielded Cat5E or Cat6). Do not use shielded twisted pair (STP)
cable.

Create the Map and Install the PV Modules and Enphase Microinverters
If you installed an Enphase PV system at this site, create the Enphase installation map and install the PV modules and Enphase Microinverters. You will scan this map later using Installer Toolkit and your mobile device. (See “Method A: Provision Devices with Installer Toolkit” on page 18.)
NOTE: You can find an Enphase installation map at the back of any Enphase Microinverter manual.
Create a paper installation map to record Enphase Microinverter (and Enphase Battery, if
installed) serial numbers and positions in the array. Peel the removable serial number label from each device and affix it to the respective location on the installation map.
Peel the removable label from the bottom of the Envoy-S and affix it to the installation map. Always keep a copy of the installation map for your records.
NOTE: If you are setting up the Envoy-S to monitor a non-Enphase PV system, you do not need to create an Enphase installation map.

1. Choose a Location for the Envoy-S
a. Install the Envoy-S near the switchboard. This ensures that the Envoy-S receives the strongest
possible communications signal from each device. When installing the Envoy-S Metered, consider the length of the CT leads when choosing the location. If you need to extend the CT leads, see “Extend CT Leads, If Needed” on page 16.
b. Install the Envoy-S in a protected dry space (such as a garage, attic, basement, or other cool, dry
location). If the Envoy-S is hard-wired outdoors, you must install it inside an IP54-rated, (or better) enclosure with conduit attachment. Use an appropriately rated enclosure if hard-wiring indoors.
NOTE: Metallic enclosures may impair Wi-Fi signal strength.
c. Mount the Envoy horizontally using the included DIN rail.
WARNING: Risk of equipment damage. When installing the Envoy-S in an enclosure, choose area for installation where ambient temperature does not exceed 46º C.
d. To wall-mount, use two appropriately sized screws and a screwdriver. Mount the DIN rail first,
and then clip the Envoy-S to the DIN rail.
2. Provide a Power Connection
The Envoy-S Metered Multiphase (ENV-S-WM-230) uses terminal blocks for power and metering connections. It does not include an AC power cord, and you must hard-wire it. When you hard-wire the Envoy-S outdoors, you must install it in an IP54-rated, or better enclosure with conduit attachment. Use an appropriately rated enclosure if hard-wiring indoors.
DANGER! Risk of electric shock. Be aware that installation of this equipment includes risk of electric shock. If you wire the Envoy-S at the sub-board, always de-energise the sub-board before beginning wiring.
a. Depending on the number of phases you will wire, use a one-, two-, or three-pole (20 A maximum)
circuit breaker for the supply wiring.
b. Make sure supply wiring is 2.5 mm
