If you can't see any data displaying on your Fronius monitoring portal, the issue is likely that your Fronius Inverter has disconnected from your WiFi network.
Don't stress! This only means your system isn't sending data to the monitoring portal. It doesn't mean that your system isn't working.
Your Fronius Inverter can disconnect from your WiFi network if you have recently:
- Changed internet providers
- Changed your modem/router
- Changed your WiFi password
- Changed your WiFi extender
- Experienced an outage or blackout
Reconnecting your Fronius Inverter to WiFi can easily be done from the comfort of your own home without third-party help.
Display LED Status Indicators
The three different lights on the display of your Fronius Inverter can help you understand what's going on with your inverter. It is important to understand these indicators before doing anything with your inverter.
Description of LED indicator status:
LED Indicator | Description |
General Status LED (Red)Lights up: - If a status message is being displayed on the monitor - If the process of feeding energy into the grid is interrupted - During error handling (the inverter waits for an acknowledgement or for an error to be rectified) | |
Startup LED (Orange)Lights up: - If the inverter is in its automatic startup or self-test phase (as soon after sunrise as the solar modules are delivering sufficient power) - If the inverter has been switched to Standby mode in the Setup menu (= feeding energy into the grid switched off manually) - If the inverter software is being updated | |
Operating Status LED (Green)Lights up: - If the PV system is working correctly after the inverter's automatic startup phase - All the time while energy is being fed into the grid |
How to Connect to WiFi
1. Confirm WiFi Signal
On your smartphone, open settings and click on WiFi settings. You should see your home's WiFi network appear here - if you don't, there is something wrong with your WiFi network or modem and you will need to have this fixed before you can connect your Fronius Inverter to WiFi. Once you've confirmed you have access to your WiFi network, you can move on to the next step.
2. OPTIONAL: Restart your Fronius Inverter
If you haven't changed internet providers, your Fronius Inverter may reconnect to your WiFi network with a simple shut-off, switch-on procedure.
To restart your Fronius inverter, turn off the AC isolator switch (if this is located in your switchboard, it will be labelled 'Main Switch Inverter Supply'.
Then, you can turn off the DC isolator switch/es.
Wait a few minutes and your Fronius inverter's lights will switch off. This indicates that your inverter is turned off and is ready to restart.
To restart, simply repeat the above steps in reverse order. Turn on your DC isolator switches, then turn on your AC isolator switch. It may take a few minutes for the lights on your inverter to turn back on.
