Blank Screen on Fronius Solar Inverter – What can you do?
As a Fronius service partner we’ve seen a number of cases were the Fronius IG series inverter screen is just blank – no lights and nothing showing on the display. If the screen and lights on your inverter are all blank there are a number of possible causes as follows, it could be a problem with the:
- Solar Panels
- DC wiring on the roof
- DC wiring between the roof and the inverter
- DC isolator on the roof
- DC isolator at the inverter
- DC plugs underneath the inverter
- Solar Inverter

As you probably start to realise from looking at this list this is a fault that is most likely going to require the assistance of an accredited solar electrician such as Gold Coast Solar Power Solutions but before running to the phone or shooting us an email check the following:

- DC plugs into the bottom of the inverter are plugged in and free from damage

Sorry to hear of your Fronius inverter issue! My recommendation would be to replace the entire unit.
Hi Rodrigo, if the SYMO inverter is blank and it sounds like you’ve shorted L2 to neutral the inverter will be damaged and need repairing. I recommend you talk to a local Fronius service partner for further assistance.
Fronius Symos inverter screen went blank. What may be the cause? What damage to inverter if the L2 on inverter AC terminal was inadvertently connected to neutral and the neutral wire to L2? Is this the reason why the screen went bl ank?
