Fronius IG Inverter State 104 Error Code Adelaide


If you have a Fronius IG solar inverter, any error messages on the inverter are called ‘State CodeFronius IG State 104 Adelaide s’.

When there is State 104 showing in the screen, this means there is an issue on the AC side, so the first thing to do is check that the power in your house is on.

Assuming the power to your house is all OK, next check the AC switches.  You will have one in your switchboard – it is probably labelled something like ‘solar supply main switch’.  Make sure this is in the ‘on’ position.

Also check under your inverter, if your inverter is not near your switchboard you should have another AC switch there, and it should be labelled ‘AC isolator’, or ‘Solar Supply Main Switch’.  Again, make sure this is on.

If either of those were off, wait a minute or two, to see if this fixes the problem.  If it does, great, if not, try a complete reboot of your system and again wait a minute or two.

HOW TO REBOOT YOUR FRONIUS INVERTER

1. Switch AC switch off

2. Switch DC isolator off (located under or next to your inverter)

3. Wait one minute

4. Switch DC isolator on

5. Switch AC isolator on

6. Wait one minute as the inverter goes through it’s start up procedure.

Here you can find more information on how to shut down and restart your solar inverter.
