Can I get a single power controller that would regulate charging of the larger deepcycle second battery from all of three inputs, solar panels, the alternator, and plug in? I imagine yes, but I am unfamiliar with the hardware.

Off my past solar research, there are off-grid systems that are designed to automatically charge a battery bank via the solar panels, but if they are not outputting power, then it uses the grid power to charge. For your 3rd power input, I would think you could use the same solar side to charge the battery.
I can't seem to find what I'm talking about, but maybe someone else knows what I'm talking about. It was some sort of inverter / charger controller.
