just to throw my shoe into the ring ...
103 @ 25% max. discharge /1.9 ah = more like 12 hours of continuous power. do you really need to run the pump 24/7? As many have pointed out (okay so I'm a lurker) the actual draw may be less than the rating indicates.
Also, when the sun shines not only will your batteries be charging but the draw will be covered by the panels. How much PV are putting into them?
@indyplumber/guercio: the windmaps for Ontario indicate a "poor" for windpower. Unless he's on a great lake or some'at.
not being an engineer means I'm big on "try it and see if it works..." so good luck!
this summer I went from small 12 volt "trailer" deep cycle, to two 235 amp/hr 6 volts in series--1 250 watt panel in; to two 395 amp/hr 6 volts in series--2 250 watt panels in; to aha, this works!
