Couple of questions about DC-Dc charging
I've been thinking about adding a DC-DC charger now that I've added 400 amp hours of AGM batteries. There are lots of useful posts but I haven't run into a couple of things I'm curious about. One ...

DC to DC buck/boost converters are extremely sensitive and responsive to errors in incoming voltage.
As an example, I had to feed a 36 volt out 12 volt in booster with 12 AWG conductor for a 10 feet in length feeder that powers a single chip 30 watt light emitting diode. The explanation is complex, but suffice it to say that's the way it is.
My 2012, 500-watt shop array had to have the Meanwell power supply mounted adjacent to the emitter because the demand of the exit wire did not allow for a nine gauge 35 foot 36 volt feeder.
