Hi @Riff-Raf, I also made the mistake to update my Axpert MKS II inverter firmware to the 72.70b patched version as my VRLA batteries were not fully charged due to the charging bug I figured that is fixed in the patched firmware. However I'm now in the same situation you were after the update with the same inverter behavior explained in your post as above. My stock firmware version was 71.50 before the update. How did you end up fixing this problem if you did manage to get it fixed? I can't see any further posts in this regard. I will probably get in contact with Mustek to get the stock firmware as that is where I bought the unit from about a month ago, but that might take some time, so if you got the firmware from them in the past and are willing to provide it, it might save some time to get the inverter up and running again.
