Fronius Solar Inverter IG40/60 State 516 Adelaide

by | Sep 3, 2017

Do you have one of the old Fronius IG solar inverters, the larger ones IG40 and IG60?FroniusIG40 Adelaide

You may get the error code STATE 516 coming up on it.  If you do, this means “One power stack exceeds the permitted limit of error messages per day (>50x)”.  Great, I hear you say, what does that mean, and can you fix it for me?

What does State 516 mean?

Your Fronius IG40 or IG60 has 2 stacks inside the inverter.  When the sun is not shining very much only one stack is utilised.  As the solar inverter works harder, the second stack comes in to use.  This is why sometimes this error code won’t show every day, only on sunny days.

Your solar inverter could very well be working fine on one stack, but the other stack isn’t working, hence the STATE 516.  This code in itself only tells us there are errors, not what is wrong.

Can you fix Fronius IG40/IG60 Adelaidemy Fronius IG40/60?

The first thing we need to do is press some buttons on the inverter to find out what the underlying messages are.  This will then tell us what we need to do to fix it.  Don’t switch your inverter off – the error messages will be cleared from the memory!

If you are happy to press the buttons yourself to find out the code, this is what you need to do:

  1. Go to the SETUP menu on the Fronius inverter
  2. Press ENTER (4th Button from the Left)
  3. Scroll down the list of options until you find STATE PS
  4. Press ENTER
  5. If you have been having a STATE 516 message on your inverter most likely you will now see the message STDBY PSOO. This means that the first power stack (PS00) is on Standby mode – it’s not producing any power.
  6. Press ENTER
  7. The inverter should now show STATE LAST and scroll to the last shown STATE code on power stage 00 (PS00).
  8. If you want to know what is happening with the second power stack press the Esc key (3rd button from left)
  9. This should take you back to the previous screen, press the 2nd button from the left to select PS01, power stage 1.
  10. Repeat from step 5 for information on PS01

Make a note of the STATE code that is showing, and check here for a list of Fronius IG STATE codes, to see what the issue might be.

As local Adelaide Fronius repairs agents we can replace parts inside your inverter to get it working again, or if it’s more cost effective, offer you a refurbished IG40/60 with a one year warranty.

If you are still in warranty we do all this with no charge to yourselves.
