Water Do we have any solar power gurus on the board?

I need some tech info from someone who's already done what I want to do to avoid "reinventing the wheel".

I have 400 watts of solar panels feeding a controller which powers a 24vdc in ground pump. The controller also charges two AGM batteries. I've been running a SurFlo 24v pump for my garden but it doesn't like it. The ground water is pump into a 1600 gal storage tank and the supply for the SurFlo pump comes off the bottom of the tank about 3 feet below the pump so a shallow well pump will easily handle it. It already has a pressure tank in the system, too.
It has been suggested to go to a 24v inverter to power a 115vac pump that will also provide water to the house.

Here's the question - what watt inverter do I need and how many more batteries do I need to add to the battery bank?

I was thinking along the lines of this -

Also, I know the amp hrs/watts have to calculated but would it be better to run the pump on 115vac or 240vac?

Thanks for any input! Directions to a solar site that deals with this stuff will be appreciated, too!
