Smart shunt install question

My smart shunt is always showing 100% charge. I have all loads going to the load side of the shunt. This includes one negative from the bus bar ( since the charger/inverter negative goes to it), the SAE plug for external solar panel, and the solar controller. Only one wire going to the batter negative from battery side of the shunt. Any suggestions? This is lithium install inside my tab.

    Maybe the solar is keeping up with the loads.  Try applying a large load (inverter) or turn off the solar charger through the app (I believe you can do that).

    Unrelated, are the charger and inverter the same component?  Or is it a charger/converter (AC converts to DC)?

    If you disconnect the power the BMV will start at 100% after reconnecting. You have to make a full charge and the SOC should be correct then.

    The Victron App has a "Charger Enabled" switch in the "Battery Sections" menu.
