Which side of my DC-DC should I put my shore power?

[TheRealPapaK]

I have 370A of alternator and a 400W solar array that is being balanced by a Renogy DC-DC MPPT charge controller. The controller has a 50A max. I have a 100A AC to DC converter for shore power that has Li charge profiles [Bulk (14.7V) Absorption (13.8V) and Float (13.2V)]. I can also change the voltages to what ever I want. I was thinking the easiest would be for me to hook up the positive to the Alternator side of the DC-DC charger since if I was plugged in for Shore power I won't be driving anyway but that would limit me to the 50A of the charger. I am new to solar but I *think* I would be ok hooking up the converter to the "House Batt" side so that the batteries could get a faster charge if I ever needed to plug into shore power. Any thoughts?

DCDC is only needed to condition the output if charge sources that do not match the precise needs of the target bank.

So a good mains charger does not need one.

A crappy garage style one, sure.

Same with solar controllers.
