[RE-wrenches] Outback inverter firmware mismatch

[William Miller]

Friends:  

As part of my ongoing love/hate relationship with Outback, I have been occasionally receiving “Inverter firmware mismatch” warnings on some Radian systems. The firmware has not been changed. 

I was told it was bad data cables. I replaced all cables on one system only to receive more of the same warnings. Then, suddenly the error warnings quit. 

Now today another system is experiencing the same warnings. 

Does anyone know what this means and how to fix it?

Thanks in advance.
