[RE-wrenches] SMA Epprom D Technical Bulletin

[Tom McCalmont]

Here’s a link to a procedure that will correct it:

If you can find a copy of it, there is also a firmware fix you can upload that will correct it so it does not recur again.

Good luck!

I remember SMA coming out with a technical bulletin to address this via a reset process and I can remember performing the reset several times, but I don’t remember the exact process/which pins to jump.  When I do a google search for the bulletin, I can’t find it.
