To reconnect Wi-Fi to a Goodwe inverter, you'll typically need to follow these steps:

Step 1: Reset Wi-Fi on the Inverter

Locate the Wi-Fi reset button on the Goodwe inverter. This is usually a small button near the Wi-Fi module or on the side of the inverter.

Press and hold the reset button for about 5-10 seconds until you see the Wi-Fi LED (usually blue or green) start flashing rapidly, indicating that the Wi-Fi has been reset and is in pairing mode.

Step 2: Connect to the Inverter’s Wi-Fi

Open the Wi-Fi settings on your smartphone, tablet, or laptop.

Look for a network name (SSID) that starts with "Goodwe" or similar, and connect to it. You might not need a password for this step, but some models may require one, which you can find in the user manual or on the inverter.

Once connected, your device may say that there’s no internet access — this is normal for this step.

Step 3: Configure the Inverter to Connect to Your Wi-Fi

Open a browser on your connected device and enter 10.10.100.254 into the address bar. This should take you to the Goodwe inverter’s Wi-Fi configuration page.

You will likely be prompted for login credentials:

Username: admin

Password: admin (These are default credentials; refer to your inverter’s manual if these do not work.)

On the configuration page, find the option to scan for Wi-Fi networks or manually enter the details.

Select your home Wi-Fi network from the list or enter the SSID and password.

Save the settings.

Step 4: Confirm Wi-Fi Connection

The inverter will attempt to connect to your home Wi-Fi.

Wait for the Wi-Fi indicator light to stop flashing and stay solid, indicating a successful connection.

Reconnect your phone or laptop to your home Wi-Fi, and check the Goodwe monitoring app (e.g., SEMS Portal) to confirm that the inverter is online.

Once connected, your inverter should start transmitting data to the monitoring platform as usual. If you still encounter issues, resetting both the inverter and the router can sometimes help.

To configure WiFi on a GoodWe inverter via the SEMS app, follow these steps:

1. Download and Install the SEMS App

Ensure you have the SEMS Portal app installed on your smartphone. It’s available on both iOS and Android platforms.

2. Create a SEMS Account

If you don’t have an account, open the SEMS app and create one using your email address or phone number.

After registration, log in to the SEMS app.

3. Connect to the Inverter’s WiFi

On the inverter, you’ll find a WiFi module (typically near the display).

Press and hold the WiFi button (or as per your inverter model) for around 5-10 seconds until you see a WiFi signal icon or light blink.

Go to your phone’s WiFi settings and search for available networks. Look for the network named something like "Solar-WiFi" or "GW_..." and connect to it.

Some models might use different names for their default WiFi. Check the inverter manual if needed.

4. Configure the WiFi Network in the SEMS App

Once connected to the inverter’s WiFi, open the SEMS app.

Tap the "Add Device" or "WiFi Configuration" option.

Input your inverter’s serial number (you can usually find this on a label on the inverter or in the app).

The app will scan and detect the connected inverter.

5. Connect the Inverter to Your Home WiFi

You will be prompted to select your home WiFi network from the available list.

Enter your home WiFi password.

Wait for the inverter to connect to your home WiFi. The app should show a message confirming a successful connection.

6. Complete the Setup

Once the connection is established, your inverter should appear on the SEMS app’s dashboard.

You can now monitor your system’s performance remotely via the SEMS portal.

If there are issues during configuration, ensure:

The home WiFi signal is strong enough where the inverter is located.

Your WiFi network supports the 2.4 GHz band, as some inverters are not compatible with 5 GHz networks.

To reconnect WiFi for a Fimer inverter, follow these general steps:

Locate the WiFi Reset Button:

On the inverter, find the WiFi module or look for the “WiFi Reset” button. The location of this button can vary by model, so refer to the user manual if necessary.

Reset WiFi Connection:

Press and hold the WiFi reset button for about 5–10 seconds. The inverter’s WiFi module should reset and go into a configuration mode (usually indicated by a flashing light).

Connect to the Inverter’s WiFi Network:

On a smartphone or computer, go to your WiFi settings and look for a network name (SSID) that is related to Fimer or Aurora, like “FIMER-WiFi” or “Aurora-xxxx” or ‘ABBxxxx”.

Connect to this network. You may be asked for a password (the Product Key or PK), which is usually printed on the inverter or available in the manual.

Access Configuration Portal:

Once connected, open a web browser and enter the IP address for the inverter’s WiFi setup page ( 192.168.117.1).

This should load the inverter’s configuration portal.

Use your Aurora vision Log in details to log in

Select Your Home WiFi Network:

In the configuration portal (Auroravision, or Energy Viewer APP etc), find the option in menu for network settings, and select the option for WLAN settings.

Select your home WiFi network and enter the password.

Reconnect and Verify:

After saving these settings, the inverter should reboot or confirm that it's connected. Go back to your device’s WiFi settings and reconnect to your home network.

Confirm Connection:

Log in to the Fimer monitoring app or web portal (if you’re using one) to confirm that the inverter is reporting data online.

Steps to reconfigure Wifi

Connect your phone, tablet, or laptop to the Wi-Fi network broadcasted by the data logger.

You should be able to find the device SSID as letters followed by numbers which will match the Datalogger serial number (small black stick coming out from underneath the Inverter).

Open a browser. In the URL bar, enter the IP address 10.10.100.254. In most cases, a window will open asking for a username and password.

Please enter Username: "admin" and Password: "123456789." (some may require password ‘admin’)

When the page opens, click on "Wizard."

Please search for your home network here and then click next.

Enter the Wifi router’s password and click next.

It may take a few seconds for the logger to finally be configured with your home network

Once complete click Ok.

If the connection to the data logger cannot be established, the following should be checked:

- The 2.4 GHz network should be used, not the 5 GHz network.

If the logger cannot be found by serial number, press the reset button for 10 seconds.

If never added before to a plant on Solis Cloud

Add your datalogger serial number manually onto your plant on the Monitoring Platform - www.soliscloud.com or by scanning the QR code on the logger via the App.
