I am currently building a camper and I am considering the charging options. I have the solar and inverter/charger worked out but am having a little difficulty working a solution for charging the camper battery from the car whilst driving.
The car already has a dual battery system with a CTEK charger charging a 120 amp AGM battery from the alternator and a solar panel on the roof of the car. I have a BMV-712 on this setup for monitoring. It works well so I am not looking to change this side of the system.
The camper set up will be lithium (so different battery types). I think I can just run an Anderson plug to the vehicle hitch from the second battery (after the CTEK charger) and connect the Orion charger to this circuit (in charger mode). I am considering the Victron Orion-Tr Smart 12/12-18A for this install. Can anyone offer their opinion on this setup given that the Orion would not directly connect to the vehicle alternator in this scenario.
