The Enphase IQ Gateway communicates system data from the microinverters to Enphase monitoring. If the Gateway is not connected to the internet, the solar system may still produce power, but monitoring data may not update in the Enphase App until the Gateway reconnects and uploads stored data.

Enphase’s current support guidance directs users to reconnect the IQ Gateway through the Enphase App by going to Menu > Settings > Connectivity > Configure Wi-Fi. The app may temporarily connect your phone to the Gateway using the Gateway’s local Access Point, or “AP mode,” during setup. This is the wireless network that the Enphase Gateway makes that you connect your phone to for configuring the actual internet wi-fi username and password so that the Gateway can report online.

Before You Start

Make sure you have:

• The Enphase App installed and updated.
• The login credentials for the system owner or installer account.
• The correct Wi-Fi network name and password.
• A phone or tablet with Bluetooth/Wi-Fi enabled.
• Physical access to the IQ Gateway or IQ Combiner.
• A strong internet Wi-Fi signal near the Gateway. (not the Gateway wi-fi network)

Do not open electrical equipment, remove dead-front covers, or modify wiring to complete this process. If the Gateway appears damaged, has no power (check Gateway breaker), or there are signs of overheating, water intrusion, burning smell, or arcing, stop and contact a qualified electrician or the equipment manufacturer.

Method 1: Connect Using the Enphase App

1. Stand near the IQ Gateway or IQ Combiner.
2. Open the Enphase App.

3. Go to:

   Menu > Settings > Connectivity > Configure Wi-Fi

4. Tap Configure Wi-Fi.

5. When prompted, allow the app to connect your phone to the Gateway.

   The app may ask you to tap Connect or Join. This temporarily connects your phone to the Gateway so the Wi-Fi settings can be updated.

6. Select your home Wi-Fi network from the list.
7. Enter the Wi-Fi password carefully.
8. Tap Join, Connect, or the equivalent confirmation shown in the app.
9. Wait a few minutes for the Gateway to reconnect.
10. Confirm that the Gateway shows as online in the Enphase App.

Method 2: Enable AP Mode Manually

Use this method if the app cannot automatically connect to the Gateway.

1. Locate the AP Mode button on the IQ Gateway or IQ Combiner.
   
   

2. Briefly press and release the AP Mode button.

   Enphase notes that AP mode allows a mobile device to connect directly to the Gateway for setup. The AP mode button should be pressed briefly rather than held.

3. On your phone, open Wi-Fi settings.

4. Look for a temporary Gateway network. It may appear as something similar to:

   Envoy_XXXXXX (the X's are part of the device serial number)

5. Connect your phone to that temporary Gateway network.
6. Return to the Enphase App.

7. Go to:

   Menu > Settings > Connectivity > Configure Wi-Fi

8. Select the home Wi-Fi network.
9. Enter the Wi-Fi password.
10. Save or join the network.
11. Allow the Gateway several minutes to reconnect and update its status.

How to Confirm the Gateway Is Connected

After setup, check the Enphase App for the Gateway status. It will take several minutes for the app to show the updated connection state.

You can also check the Gateway’s communication indicator. On many Enphase Gateway/Combiner units, the network communications LED is used to indicate whether the Gateway is communicating. LED behavior can vary by model, so refer to the IQ Gateway manual or Enphase support documentation for model-specific status meanings.

Troubleshooting

The Gateway Wi-Fi network does not appear on my phone

Try the following:

• Stand closer to the Gateway.
• Briefly press and release the AP Mode button again.
• Wait 30–60 seconds for the temporary network to appear.
• Turn your phone’s Wi-Fi off and back on.
• Make sure you are not holding the AP Mode button too long unless instructed by Enphase support or the app.

The app says the Gateway cannot connect to Wi-Fi

Check the following:

• Confirm the Wi-Fi password is correct.
• Make sure the home Wi-Fi network is working with another device.
• Move the router or access point closer, if possible.
• Avoid weak signal areas, metal enclosures, thick walls, or long distances between the router and Gateway.
• Confirm the network does not require a web browser login page, such as hotel, campus, or public Wi-Fi.

The Gateway connects but later goes offline again

Common causes include:

• Weak Wi-Fi signal at the Gateway.
• Router or internet service changes.
• Changed Wi-Fi name or password.
• Router security settings blocking the device.
• Power interruptions to the Gateway.
• Network equipment being rebooted or replaced.

For a more reliable connection, consider relocating the router/access point, adding a properly configured Wi-Fi extender or mesh node, or using an approved wired networking option where supported by the installation.

I changed my router, internet provider, or Wi-Fi password

Reconnect the Gateway using the same steps above. A changed network name or password will usually require the Gateway Wi-Fi settings to be updated.

Safety Notes for DIY Installers

Connecting the IQ Gateway to Wi-Fi is a low-voltage/network configuration task, but the Gateway may be located in or near electrical equipment. Do not remove covers, alter wiring, bypass breakers, or access energized components unless you are qualified and authorized to do so.

Contact a licensed electrician, qualified solar installer, or Enphase Support if:

• The Gateway has no power.
• Breakers are tripping.
• There is visible damage, heat discoloration, water intrusion, or a burning smell.
• The Gateway is inside an electrical panel or combiner section that requires opening energized equipment.
• The app reports equipment or grid-related errors that are not limited to internet connectivity.

Support Information to Collect Before Escalating

If the Gateway still will not connect, collect as much of the following information as you're able to before contacting support:

• Site name or system ID.
• IQ Gateway serial number.
• Gateway model, if visible.
• Enphase App version.
• Phone operating system: iOS or Android.
• Wi-Fi router make/model, if known.
• Whether the Wi-Fi name or password recently changed.
• Screenshots of any error messages.
• Photos of the Gateway LEDs.
• Approximate distance between router and Gateway.
• Whether other devices can connect to the same Wi-Fi network.
