Enphase Envoy Wi-Fi Setup & Troubleshooting

For Enphase solar systems, the Envoy is the solar motioning unit. It collects solar production data from the solar microinverters and uploads this data to the cloud though the internet. Solar production data can then be viewed from any phone, tablet, or computer from anywhere.

This guide explains how to setup or restore the Wi-Fi connection with your wireless router/modem for the Enphase Envoy, Envoy-S and IQ Envoy.

First, Locate Your Envoy

The Envoy is typically located either in the garage or outside in a weatherproof box. If you are unable to find your Envoy, Enphase has tips for where to look. Click Here.

Refer to the photos below to determine what your Envoy looks like. You may have either an Envoy-R, Envoy-S, or IQ Envoy.

Select Your Envoy for Wi-Fi Setup Instructions


To connect via Wi-Fi, the Envoy requires one of the following USB wifi adapters connected to the USB port on top:

  • TP-Link TL-WN721N
  • TP-Link TL-WN722N v1 (Versions 2, 3 and later are not compatible) *

* Important: TP-Link released an updated version of the TL-WN722N with a different chipset (versions 2, 3, and later) that is no longer compatible with the Enphase Envoy. Because the product packaging does not distinguish between different product versions, we no longer recommend purchasing a TL-WN722N to make the Envoy wifi capable. If you have a TL-WN722N that has previously worked with your Envoy, it will continue to work as it has the required v1 chipset.

Wi-Fi Setup & Troubleshooting Steps

  1. Unplug both your router/modem and Envoy. Wait 30 seconds. Plug the modem/router back in, but keep the Envoy unplugged. (Please trust us on this step. When we say unplug, we mean literally unplugging.)
  2. If it is not plugged in, plug the TP-Link USB adapter on one of the USB ports on the Envoy.
  3. Connect the Envoy directly to your router via an ethernet cable. It is okay if you temporary move your Envoy to do this.
  4. Plug the Envoy in and wait for it to boot.
  5. Your Envoy will display an IP address on its screen (such as or The actual IP address will vary so look on the screen itself. On a Windows or Mac computer, using the Firefox web browser, enter the IP address displayed. For example, if the screen says, enter in Then, press the enter key.
  6. You will visit a webpage. On the top of the webpage, click on the “Administration” link towards the top.
  7. The username and password are both admin.
  8. On the gray box to the left, click on the link labeled “Wi-Fi Configuration”.
  9. From the list, select your wifi network (please note that the Envoy only supports 2.4 GHz wifi, not 5 GHz). Enter your wifi information in and click “Test Connection”.
  10. The Envoy will now test to make sure the wifi information entered is valid. This may take up to 5 minutes so please be patient on this step.
  11. If you entered your wifi information correctly, you will see green text saying Connection Successful. You might have to scroll down to find this message. Underneath, there is a button to “Join Network”. Click on that button.
  12. Once joined, please disconnect the ethernet cable. Un-plug and re-plug the Envoy.
  13. The screen should display an IP address starting with a W (i.e.: W192.168.1.29 or W10.0.0.43). To the right of this screen, you should also see +Web. Your Envoy is now connected to the internet.
  14. Return the Envoy to its original location and plug it in.
  15. In most cases, it takes on average 72 hours for all backlogged data to upload. During this time, you may see errors such as “microinverters not reporting”. This is normal.

Envoy-S or IQ Envoy

  1. Unplug your modem/router for 30 seconds. Plug it back in. (Please trust us on this step. When we say unplug, we mean literally unplugging.)
  2. Briefly press and release the button between the Phone and Lightening icons (as pictured below). Do not hold the button down.
  3. The second LED next to the “Phone” icon will light to solid green (as pictured below). If the LED light does not turn on, please see the “Troubleshooting Tip” right after the picture below.Troubleshooting Tip: If the LED next to the “Phone” icon does not turn on, please shut off your Envoy. This can be done either by unplugging the Envoy or flipping the breaker. You will know the Envoy is off when all LED lights turn off. Once off, wait 30 seconds. Then, turn on the Envoy. Wait 5 minutes for the Envoy to boot. Then, try Step 2 again.
  4. Select a wifi-enabled Mac or Windows computer you would like to use to configure the wifi on the Envoy. Disconnect any ethernet cables it may be connected to. Be sure to keep your wifi-enabled device line of site within 6 feet during this setup.
  5. Go to the wifi settings on your device. Search for wifi network “Envoy_XXXXXX” where XXXXXX is the last 6 digits of your Envoy serial number.
  6. Write down these 6 digits as they will be needed later. Then, connect to the wifi network.
  7. Open your web browser. For best results, we recommend you use the Firefox web browser. Type in Or, if you have this guide already open on the computer you are using to set up your Envoy’s wifi, click here. (We highly recommend using Firefox. If you are having issues in subsequent steps, please try again using Firefox.)
  8. A webpage will open. Scroll down to “Wi-Fi” and click on the link.
  9. A prompt to sign in will appear. The username is envoy and the password is the last 6 digits of your Envoy serial number, which you wrote down back in step 6.
  10. Click on “View Networks”. (If you are seeing “Attempting to Reconnect”, click on “More Info” and then click “Forget this Network”. Then, click “View Networks”.)
  11. Select your wifi network, enter your wifi password, then click “Connect”. It may take up to 3 minutes to connect to your wifi network.
  12. You will receive a “Successfully Connected” prompt. Click “OK” to confirm.
  13. On the Envoy, check the LED next to the “Cloud” icon. It should be solid green. This means your Envoy is successfully connected to Enphase servers and it will again upload solar production data.
  14. You may re-connect your computer’s wifi back to your regular network and move your wifi-enabled device back to its original location.
  15. In most cases, it takes on average 72 hours for all backlogged data to upload. During this time, you may see errors such as “microinverters not reporting”. This is normal.

Down Monitoring ≠ Down Solar System

  • If your internet connection is lost, this does not affect your system’s production. Your system will continue to produce power normally.
  • Your solar system will continue to collect production data and upload it once the internet connection is re-established.
  • Enphase systems can backfill on average 6 months of data.
