I'd set for 14.4V at the Meanwell, unless you are running wire a long enough distance that will cause voltage losses. Measure V at the terminals on the Meanwell, and V at the end of the wires right before it hooks up to the battery banks, but not connected to the battery yet.
You'd like to get 14.4V at the battery connection right at the terminal, for AGM battery packs. Set accordingly at the Meanwell to achieve that.
The second post shows that some folks have not been reading much in the tech section for very long. Disregard the comment. My post along with Mex's confirms he lost that bet.
