Fronius inverter WiFi reconnection assistant
Is your Fronius inverter no longer producing data? Let’s get that back for you with the Island 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.
Important: this post is pending an update. If you cannot reconnect your Fronius Inverter and are a Island Energy customer, please contact Island Energy
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 WiFi 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
Physical access to your Fronius inverter.
A WiFi-enabled device such as a smartphone or tablet.
Patience, the average reconnection time is 10mins.

Accessing the user interface of the inverter via WLAN
Touch the sensor at the front of the inverter once briefly to activate the WLAN access point. The right LED flashes blue when the access point is open.
Connect your laptop / tablet / smartphone to the WLAN network “fronius_3xxxxxxx” that is now available. The network security key can be found on the rating plate on the side of the inverter. In the case of inverters with a rating plate that does not have a password printed on it, the network security key “12345678” applies.
Enter the following IP address in the address line of your browser (e.g. Google Chrome): "192.168.250.181".
Setting up the Internet connection of the inverter (e.g. after replacing the router)
Proceed as follows to configure the network, for example after replacing a router, and to establish an Internet connection to the inverter:
On the user interface of the inverter, go to “Communication” à “Network”.
Select the desired connection mode “Ethernet” or “WIFI”. For "Ethernet", select the setting "Automatic" or "Static". In most cases, the setting "Automatic" is sufficient. For example in corporate networks, the setting "Static" may be mandatory. To set this up, please contact the network administrator of the system.
For “WIFI”, select your home network under “Available Networks” and enter your home network’s WIFI password. Select the setting “Automatic” or “Static”. In most cases, the setting “Automatic” is sufficient. For example in corporate networks, the setting “Static” setting may be mandatory. To set this up, please contact the network administrator of the system.
Click "Connect" to apply the settings.
