Hi! I have a Fronius Sunpower inverter model SPR 11401f-1 UNI It threw an error STATE 449 I was wondering what is the cost and means of how to get this back up and running. Happy to ship it to you etc if that works. thank you! Will
Instead of replacing a full pinci board for $$$, most of the time you can check the relays. Especially the Song Chuan 30A mains relays get burned out after a few years. They cost just $3. Watch the "relay" led inbetween the two relays turn red during startup and immediately giving a state 439. In that case its just the relay. I;ve had this problem with 2 different fronius IG-PLUS 120s, and already needed to change 3 relays the last couple of months.
And they function as new again, mine burnt 2 relays, Ron's 1....,.at Fronius they charge € 500,00 per board :-( so whe "earned" serious cash, thanks mate

Does the relay just plug into the pinci board or is it soldered?
I have this same inverter but with the fault in the "low power" display, what will I have to replace?
