BMV resetting each morning?

Hi all, I am new here. I recently had some upgraded solar work done and had an mppt charger added (not Victron). Since then my SOC seems to be 100% each morning and this seems hard to believe considering we are using power overnight. I can’t find anything in settings that resets SOC at a particular time, could something else be causing it?

Thanks

Since posting I have changed some settings. Increased charged voltage to 14v and decreased tail to 2.1% based on some YouTube videos I have seen.
SOC is showing 100% but I think that is because I accidentally pressed the manual synchronisation button?

Hi @teamflames,

looks like you have a Lithium setup. Don't know what the settings have been before, but they look ok now. In most cases 'Charged voltage' is set wrong and will cause early or late synchronising. You could raise 'tail current' up to 4%.
