Envoy-S Metered Multiphase Installation and Operation

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.

Envoy-S Metered Multiphase Installation and Operation

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.



One of the following Web browsers with cookies enabled: Chrome 5 or higher, Firefox 11 or higher, Internet Explorer (IE) 9 or higher, or Safari 5 or higher

Envoy-S Metered Multiphase Installation and Operation

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.

System Metering

The Envoy-S monitors up to 600 Enphase Microinverters and up to 39 Enphase AC Batteries.

Envoy-S Metered Multiphase Installation and Operation

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.
