Yeah, I would want to run the batteries at at least 24v (which is simple
enough if you're using two 12v batteries anyway).
Lots of different ways to do this... the simplest way would probably be
Traco TSP-BCM48 paired with whatever 48v DIN rail power supply (there are
several different options that would work from Traco or Meanwell), and
connect it to a SiteMonitor Base for monitoring.
