If you think about it, why would the reading change without a "significant event", like charging or discharging?
Because the Victron Smart Shunt is displaying real time voltage 24/7. This VE.Direct is the same technolgy that if I spend a $1,000 to add the Cerbo GX it would show what the Smart Shunt has on the tablet inside the RV. The VE.Direct is just sending via bluetooth.
Also, when the VE.Direct is working correctly, it is displaying the real time values in 1/100dreths
So is the "Voltage" display in the pic you posted the house battery voltage? If so, why didn't that value change when you started the engine? I'm not familiar with Victron specific apps...
This is good question on why house voltage did not go from 13.51vdc to 14.4vdc? I took a picture of what the DC2DC is saying and shows 14.4vdc being sent to the House battery when the engine was running. FWIW the Smart Shunt itself is only reporting 13.51vdc and the physical house battery is also showing 13.6 vdc
So the DC2DC is saying 14.4vdc output but only 13.6vdc is actually on the battery. I need to measure the actual output coming out if the DC2DC. My guess it is related to actual profile for Lithium or maybe the BMS is preventing from taking a charge?
I will turn a few things on tonight to drain the battery down from the 100% SOC
