Operation SAFETY Read this First Follow the instructions in this manual. These instructions are key to the installation and maintenance of the Enphase Envoy-S Standard™ and the Enphase Envoy-S Metered™. To ensure the safe installation and operation of the Envoy-S, note the following safety symbols that appear throughout this document to indicate dangerous conditions and important safety instructions. DANGER: This indicates a hazardous situation, which if not avoided, will result in death or serious injury. WARNING: This indicates a situation where failure to follow instructions may be a safety hazard or cause equipment malfunction. Use extreme caution and follow instructions carefully. NOTE: This indicates information that is very important for optimal system operation. Follow instructions closely. Safety Instructions DANGER: Do not install current transformers (CTs) when current is flowing in the sensed Risk of circuit. Always install CT wires in the terminal blocks before energising the electrocution! sensed circuit. DANGER: Do not attempt to repair the Envoy-S; it contains no user-serviceable parts. Risk of electric Tampering with or opening the Envoy-S will void the warranty. If the Envoy-S shock. Risk of fails, contact Enphase Customer Support for assistance fire. (enphase.com/global/support-request). Refer servicing to qualified personnel. Only qualified personnel should troubleshoot, install, or replace the Envoy-S. Do not wire unused terminals or terminal blocks on the Envoy-S. DANGER: Do not use Enphase equipment in a manner not specified by the manufacturer. Risk of electric Doing so may cause death or injury to persons, or damage to equipment. shock. If you wire the Envoy-S at the sub-board, always de-energise the sub-board before beginning wiring. WARNINGS: Before installing or using the Envoy-S, read all instructions and cautionary markings in the technical description and on the Envoy-S. Risk of equipment damage. When installing the Envoy-S in an enclosure, choose area for installation where ambient temperature does not exceed 46º C. NOTES: Perform all wiring in accordance with all applicable local electrical codes. To ensure optimal reliability and to meet warranty requirements, the Enphase Envoy-S must be installed according to the instructions in this manual. 5  2016 Enphase Energy Inc. 141-00031 Rev 01 Envoy-S Installation and Operation The Enphase Envoy-S The Enphase Envoy-S is an integral component of the Enphase Microinverter System. It operates between the Enphase Microinverters and the Enphase Enlighten ™ web-based monitoring and analysis software. The Envoy-S monitors the microinverters that are connected to the PV modules. It collects energy and performance data from the microinverters over on-site AC power lines, and it forwards that data to Enlighten, via the Internet, for statistical reporting.  The Envoy-S Metered uses precision Current Transformers (CTs) to measure PV production and home energy consumption.  The Envoy-S Standard offers microinverter PV production monitoring. How the Enphase Microinverter System Works 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. This integrated system maximises energy harvest, increases system reliability, and simplifies design, installation and management. The Envoy-S operates as a gateway between the Enphase Microinverters and Enlighten. The Enphase Enlighten web-based monitoring and analysis software analyses the data collected by each communicating microinverter. Enlighten automatically detects any shortfall in energy production, identifies possible causes, and suggests solutions. Enlighten constantly monitors every Enphase Microinverter 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 even access Enlighten on your mobile device and view current performance information wherever you are. 6  2016 Enphase Energy Inc. 141-00031 Rev 01 Envoy-S Installation and Operation 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. Enlighten Microinverters Envoy-S Switchboard To Internet Router POWER LINE NETWORK COMMUNICATIONS COMMUNICATIONS Pre-installation Checks Review the following pre-installation checks before you install the Envoy-S. Select the Envoy-S Type to Install  The Envoy-S Metered uses precision Current Transformers (CTs) to measure PV production (accuracy 2.5%) from the solar main supply switch and home energy consumption from the AC mains.  The Envoy-S Standard offers microinverter PV production monitoring (accuracy +/- 5%). 7  2016 Enphase Energy Inc. 141-00031 Rev 01 Envoy-S Installation and Operation 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. To download, 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 4.2 or later, or  An iOS device running iOS 7.0 or later, specifically an iPhone 4 or later or an iPod Touch 5th generation Enphase Installer Toolkit mobile app Box Contents Check the shipping box for the following items:  Enphase Envoy-S  AC power cord (included with ENV-S-WB-230-F, -G, and -I)  Two split core current transformers (CTs) for production and consumption metering (included with ENV-S-WM1-230)  Length of DIN rail for mounting  Fer
