Here is a question for the learned solar system folks.. I have a Tracer 40 am MPPT charge controller and a Xantrex 20a smart charger. Currently, the Xantrex is across the batteries. I do have maste...

Do not ever try to pass the charging from a charger or converter through a solar controller!!! (The controller works by shorting the solar panel, which is fine, but your charger or converter won't like being shorted! )
Getting to a true full is just a matter of time and amps to the battery at a high enough voltage to create "gassing" ( mid-14s)
Solar can do it but often runs out of daytime too soon. The charger can do it on shore power but on generator now it runs out of time too. the last 10% of the recharge takes hours and hours.
If you get the math right for your situation, you can run the charger first to get the batts up quicker than the solar can early in the day and then let the solar finish the recharge taking all the rest of the daytime. Problem is you also are camping, so that means getting the batts full before say 6pm when you start using the 12v to make supper and then watch a movie say.
