Read our step by step guide to shut down and restart your Fronius inverter safely.
Before you start
1. Turn off the AC supply
Find the Solar Inverter Main Switch or AC isolator (usually located near the switchboard).
Switch it OFF.
2. Turn off the DC isolator(s)
The DC isolators are found next to or below the inverter and are typically labelled PV Array DC Isolator.
Switch them OFF.
3. Wait 5 minutes
Allow the inverter’s lights and display to fully power down.
4. Turn the DC isolator(s) ON
Switch the DC isolators back ON.
5. Turn the AC supply ON
Turn the Solar Inverter Main Switch or AC isolator back ON.
6. Allow the inverter to restart
The display should show normal startup screens, and the green power LED will illuminate once it begins generating.
If your model includes WiFi indicators, check for a solid blue WiFi light to confirm connection.
7. Check Solar.web monitoring
Open Solar.web and confirm that your system data is updating correctly.
