Such supplies exist for some levels of power. Very popular in the MiniITX community where power levels are < 300W.[1]. There is also a wealth of material on developing DC to DC converters and a number of modules for the same.
For a non-engineer putting something together I would look at DC-DC converter modules (see https://www.digikey.com/products/en/power-supplies-board-mou...) that provided the necessary power rails, at the power level that was required.
Such a solution would not be compact and integrated like one that was designed from scratch to be used in this way, but would certainly work.
I used one of the MiniITX supplies to power a system that is mounted in a box on a tree with a solar panel charging a deep cycle battery. It is the download/storage point for a number of wildlife cameras nearby.
