Monitoring Your Fronius Inverter

Fronius inverter Wi-Fi Reconnection Assistant

Is your Fronius inverter no longer producing data? Let’s get that back for you with the PSW Energy Fronius Inverter WiFi Reconnect guide. The great news is that this is often only ever a minor issue. Chances are the solar energy system is still producing power, you simply can’t see this information being logged anymore through the Fronius Solar.web portal.

The following Fronius inverter WiFi reconnect guide is applicable for all Fronius WiFi enabled SnapInverter models that include the Fronius Galvo, Primo, Symo and Hybrid models.

Likely causes

Ask yourself the following questions;

Was there a blackout or a power outage recently?
Has the modem been switched off for any reason recently?
Have you recently changed to the NBN?
Has the modem been changed or upgraded?
Has the solar system been switched off recently?
Has an electrician been working on the property?

If you answered yes to any of the above, there is a high chance your Fronius inverter disconnected from your WiFi network. Your inverter is now trying to communicate through an IP address no longer available from your modem.

It’s important you know the steps to reconnect any WiFi based device as IP addresses will continue to change over the system’s lifetime. Here is how to get your Fronius inverter WiFi reconnected.

Note : If your inverter has disconnected from your Wi-Fi network, this will not affect your solar energy system’s ability to produce energy. It will only prohibit communication to the Fronius Solar.web cloud server, allowing you to view your solar production information.

Required before initiating the sequence

Ask yourself the following questions;

Step 1: Activate Wi-Fi Access Point

Stand in front of your Fronius inverter. On the Fronius inverter display, a number displaying the current solar production should be visible, press the BACK button to enter the menu options carousel.

Locate the setup mode by pressing Button 2 , and scrolling to the right until you locate the SETUP menu option.

Reaching the SETUP menu option, press button 4 to ENTER.

Scroll down (button 2) to the Wi-Fi Access Point, and select ENTER (button 4).

A message will appear Activate Wi-Fi AP? Press ENTER (button 4) once again to activate the WiFi access point.

When the WiFi access point has finished loading, it will display the inverter connection details.

Step 2: Connect device Wi-Fi

Once the inverter has activated the Wi-Fi access point, go to your WiFi-enabled device and open up the Settings.

Locate the Wi-Fi settings and select the Fronius Inverter network (FRONIUS_240.#####).

Enter the password displayed on the inverter screen (12345678) and tap join.

Step 3: Access Setup Assistant

Once the inverter is connected to your WiFi-enabled device, open up your preferred web browser on the device (chrome, safari, explorer etc).

In the web browser, enter the IP address 192.168.250.181 in the search bar. Locate the settings menu on the right side of the page.

Locate the settings menu on the right side of the page. On the left-hand side of the page, select Network.

Step 4: Network setup

Once the Network setup page has loaded, two columns are displayed Connection mode (left) and WLAN Settings (right)

1. Under the Connection mode column (left) select the Solar.web via WLAN option.

2. Under the WLAN Settings column (right) select the network you would like to connect your Fronius inverter to from the list of available networks.

TIP : Have your network name and password handy.

3. Tap the Set… button located on the bottom left-hand corner below the Available networks box. A small box will pop up called WLAN connection. Enter your network password then select Save.

CHECK: When you have successfully saved your network password, select Configure WLAN IP button, and ensure the Get address is set to dynamic (not static), then select OK.

4. Select Connect. A series of connection attempts will cycle with your chosen network. Once connected, a Network status page will display the modem connected to the inverter but No internet connection. In the WiFi settings on the mobile device which you are using, disconnect with the Fronius inverter and resume using an alternative WiFi source.

Log into Fronius Solar.web, and your Fronius inverter should now be reconnected.

They did a fantastic job with the installation and showed us how to get the mobile app working and explained everything perfectly. They took all the packaging away so we didn’t need to dispose of anything and even vacuumed up after they finished and everything was installed very neatly. Considering the amount of work required on the roof, only two roof tiles broke but they replaced them with new ones and even left us a couple of spares. Overall we’re very happy with the job they did.

Brett and his team turned up on time, we had a quick discussion on how the installation process would play out and where I would like the inverters and cables leading to them. Following their departure there was no trace of them being here, everything was left clean and tidy. I would highly recommend them.

So professional we are very happy. We were stepped through the whole process and everything was done as we were advised. They even called our energy provider so we didn't have to follow up on anything ourselves. The installer who did the install cleaned up afterwards and took all the rubbish with him. So happy it was such an awesome experience to have professional people sort it all out for us. Would give them 10 stars if I could.
