Moving from 2 parallel lead acids to one lifepo4 battery and need to add bus bars to reduce battery terminal connections. So, one battery has one line that is the solar connection, straight forward single direction power flow. However the other battery connection can have power flow to battery (coming from the converter/charger) or can have power flow out from the battery. This is because there are small circuit breakers that jump power to the dc fridge, tongue jack and emergency break. If shore power is on, power flows to the first breaker and then flows to others the others to power those items and to charge the battery. When shore power is disconnected power flows from the battery to those breakers to power this list. If I connect the solar and that one birectional power cable to a bus bar and just one cable to the battery will it work. Seems like solar would be going to the battery and if not connected to shore power, the battery would want to send power out over that same single cable. Thus dc 101?
 
You’re going to want a switch like this:

I installed one 2 years ago and it works like a charm!
