To troubleshoot this issue: • Check the Installer Toolkit mobile app to see which microinverters are not communicating. • Check that the circuit breaker(s) for the PV array are in the “ON” position. • Verify that the PV modules are connected to the microinverters. • Verify the PV module DC voltage is within the allowable range for the microinverter. To install the Enphase Envoy-S Standard™ gateway, read and follow all warnings and instructions in this Guide and in the Enphase® Envoy-S Installation and Operation Manual at: enphase.com/support. Safety warnings are listed on the back of this guide. PREPARATION How It Works Enlighten Microinverters Envoy-S Switchboard To Internet Router POWER LINE COMMUNICATIONS NETWORK COMMUNICATIONS If you are using Wi-Fi and the Network Communications LED lights solid amber, make sure that the broadband router is connected to the Internet by checking that other devices at the site can access the Internet. If you are using the Enphase Mobile Connect modem and the Network Communications LED remains off or lights solid amber, see Troubleshooting in the Enphase Mobile Connect Installation Guide. For any connection method, you can troubleshoot network issues with the Installer Toolkit mobile app by tapping the Network button, then Diagnostic Tools. If you replace the broadband router, configure the Envoy Wi-Fi settings for the new Wireless Network Name (SSID) and password. C ) Decide whether to power the Envoy-S using the included AC power cord or by hard-wiring it in an enclosure. If you hard-wire the Envoy-S, you must install it in a non-metallic, IP54-rated, or better enclosure (use an appropriately rated enclosure if hard wiring the Envoy-S indoors) with conduit attachment. Do not drill holes on the top of the enclosure or anywhere that allows moisture ingress. If you use the power cord in an enclosure, the socket must be appropriately rated. D ) If you are installing the Envoy-S in a multi-phase application, install a phase coupler on the load side of the over-current protection device. See the Technical Brief on Phase Coupling for your region at enphase.com/support. Consult Enphase support for compatible devices. E ) Decide how to connect the Envoy-S to the Internet: Wi-Fi, an Enphase Mobile Connect modem, or Ethernet. Envoy-S Display and Controls Track system installation progress with the Enphase Installer Toolkit mobile app. The LEDs on the Envoy-S are solid green when a function is enabled or performing as expected, flashing when an operation is in progress, or solid amber when troubleshooting with Installer Toolkit is required.

AP Mode Button Press to enable Envoy’s AP Mode for connecting with a mobile device. Hold for 5 seconds to start WPS connection to a router. Power Production LED Green when microinverters are producing power. Microinverter Communications LED Green when microinverters are communicating with Envoy-S. Device Scan Button Press to start/stop 15 minute scan for microinverters over the power line. F ) Make sure you have the following optional items, if needed: • Enphase Mobile Connect modem (order CELLMODEM-02) • Ethernet over power line communication (PLC) bridge with Ethernet cables [order EPLC-02 (EU), EPLC-03 (UK) or EPLC-04 (AU)] • Ethernet cable (802.3, Cat5E or Cat6, unshielded) G ) Install the PV modules and microinverters as directed by the installation manuals. H ) Create a paper installation map to record microinverter serial numbers and positions in the array. You will scan this map later using Installer Toolkit and your mobile device. • Peel the removable serial number label from each microinverter and affix it to the respective location on the paper installation map. • Peel the removable label from the bottom of the Envoy-S and affix it to the paper installation map. • Always keep a copy of the installation map for your records and to upload to Enlighten later. Internet connection issues If you are using Wi-Fi and the Network Communications LED remains off: • The WPS connection window may have timed out. Retry the connection steps. • Make sure that the broadband router is operational by checking that other devices at the site can access the network. • Be aware that metal enclosures or obstructions impede wireless communication. • If you cannot see your router or access point in the list on the Envoy, or cannot maintain a connection, it may be necessary to add a wireless repeater to extend the network range. A ) 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-S to track system installation progress. To download, go to enphase.com/toolkit or scan the QR code at right. B ) Check the box for the following items: • Enphase Envoy-S Standard gateway • AC power cord • Length of DIN rail for mounting • Ferrite bead to attach to your Ethernet Cable, if used Power production issues If the Power Production LED lights solid amber, check the Installer Toolkit mobile app to see which microinverters are not producing: • If none of the microinverters are producing power, there may be a grid or wiring issue. First, verify that there is proper input voltage and frequency from the grid. Next, check the breaker and wiring, starting at the switchboard. • If all of the non-productive microinverters are on the same branch, check the breaker and wiring starting at the junction box for the affected branch. • If only one or scattered microinverters are not producing power, first check to see that the AC connectors are fully seated in the Engage Cable connectors. Next, check that each module is providing the required startup voltage for the microinverter (22V). A PV module that is failing or that is undersized may not generate enough power for AC conversion. d Installing the Enphase Envoy-S Standard Microinverter detection issues If the Microinverter Communications LED lights solid amber, it may be a result of low light levels. If there isn’t enough sunlight to power up the microinverters, they can’t communicate with the Envoy. c (Models ENV-S-WB-230-F, -G, and -I) Q U I C K I N S TA L L G U I D E LED overview Note: If needed, you can find an installation map at the back of any Enphase Microinverter Quick Install Guide.
