not many folks may have direct exerience with this, since usually solar is hooked up to a separate battery bank (the "house" batteries in an RV, for instance).
i _think_ what you want to do will work just fine -- but you should definitely talk to the maker of the solar controller to make sure that's the case. in the case of house batteries, there are often multiple chargers connected to the battery bank at once: for instance a solar controller and a shore power charger. what i don't know is if a solar controller and the van's vehicle charging system can work together.
please post what you find out!
