want to have this as a separate thread just for better visibility, so it does not get lost or mixed up with the other problem I had.
Problem is with firmware 459 and Multi Compact 12/1600/70. It keeps staying in absorption mode forever, regardless of battery state (full) and does not switch to float and in the end will toast my battery bank. Edit: and I just realised while switching the Charger Mode on via Remote Console, that it goes straight into absorption. No bulk at all.
VRM access possible to switch Multi On/Off/Charger Only, if someone wants to try. Setting file available as well. Hope someone from the developers can look into it.
