Combination Converter / Solar Controller?

Converters have a constant AC input rectified to DC for charging. The circuit that controls the charging is typically timer based. A solar charge controller has a dynamic DC supply and can be set for different amounts of charge voltage, along with different durations. Most good solar controllers also have a timer based "load" output. To make a converter do double duty also a solar charge controller would require all of the circuitry of a typical solar controller. There wouldn't be a lot of sharing for the different tasks.
I don't see any economy of function but there would be the elegance of just one housing.
