1 Solar panel--2 Seperate batteries

I have two battery banks, one controller, and one solar module. I chose to control the charge current from the solar with a battery master disconnect switch that has options of single bank or both banks charging. The negative phase is tied together with a buss bar in a separate box. I also have the inverter and converter switched in the same manner, that is probably overkill for most but I wanted the options to be available. Most of the time, all of the 12v system is connected in parallel.
