I have rather simple system, I think, for my van. Trying to charge a house battery from solar and vehicle battery. For now I am just trying to get the Solar to work independently ( leave the DC/DC charge out of equation for now). I have looked at the Victron Van concept, which is much more over complicated in comparison to my setup. So I am having troubles understanding the schematic I need.
The MPPT keeps charging the battery well past 13.2V. (I recently changed this down from 13.9V, but it didnt help) It will continue on up towards and past 14V, then battery will read "Busy" , fully charged and stop taking charge. Then it sends a Over Voltage Alarm, referring to "Allow-to-charge contact"
What stops the MPPT or DC/DC from charging when the battery gets fully charged? Do I need an additional Battery Protect? I am not sure if I am missing equipment or have the wrong settings.
All Victron equipment:
12.8V 100Ah LiFePo4
Smart Solar MPPT 75/15
Orion Tr Smart 12/12-30
Smart Battery Protect 12/24-100 (1)
BMV 712 Smart
VE Bus BMS
Lynx Distributor 1000 ( which I dont think I even need)
2 - 100W Renogy
