I'm doing an RV conversion that I want to wire in 12V for the house. The vehicle runs on 24V (2 x 12V starter batteries). I'm just at the planning stage (haven't bought anything yet or decided on panel or battery bank size etc).
I'd like to set up the solar batteries and starter batteries so that the RV engine will charge the solar batteries. My current RV does this via a VSR and controller, but it's 12V to 12V. Does anyone know if I can do this 24V to 12V?
I'm also not clear if such a system charges the starter battery from the solar panel (via the solar battery). I assume it does but I've not tested it.
