Good shout @VickyFisher - the Orion-Tr Smart is a solid choice for that. One thing worth considering is whether you've got the engine detection set up properly.
@ForestDaz has hit on something crucial there. The variable voltage alternator issue on the TGE 2026 is what I'd actually start diagnosing first before anything else.
Great thread this. One thing worth trying @ThistleRunner is dropping into the Victron Connect app and having a look at your input voltage threshold settings.

@StormyWelder don't let @BoxerProject put you off entirely — the 48/3000 might be oversized for a shepherd's hut on paper, but if you're planning any meaningful loads (induction hob, space heater,...
