As part of my ongoing love/hate relationship with Outback, I have been occasionally receiving \u201cInverter firmware mismatch\u201d warnings on some Radian systems. The firmware has not been changed. <br>
<br>
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. <br>
<br>
Now today another system is experiencing the same warnings. <br>
<br>
Does anyone know what this means and how to fix it?<br>
<br>
Thanks in advance. <br>
<br>
