Yes, I am using a solar controller to charge my 12V engine battery from the 48V.  I think the reason I did that was the output for 1 unit could be higher than available, and it was also programmable from within the victron app.  

I really like being able to program the output as well as being able to see history of power usage.  It came in handy when I had a slide seal blow out, I could tell how much extra power was being used by the 12v air compressor so I could determine if I had to worry about the amount of time it was blown before I replaced it.  It turned out to be less than 2 days!
