I suggest the Intellipower PD4000. It is a combination of 120v distribution, 12v distribution, and 45 amp charger/converter. It is available for wet cell or AGM batteries. It also has terminals for a 12v main disconnect.
The big advantage of this unit is space conservation. Instead of separate boxes for 120v, 12v distribution, and 12v charger, it all comes in one small package. We haven't used it long enough to find any problems. I don't know how it might integrate with solar.
Rob at Van Specialties should be familiar with this unit since they provided and put it in my van.
