Have you looked at the lifepo4 batterys? Im thinking of useing 4 100ah 3.2v cells instead of a lead acid when i setup mine. A 100ah should weigh about 24lbs and can be discharged 80% as opposed to leads 50-60% and the life battery has no voltage sag and the current draw is linear so 100ah life battery would be the same as a 200ah lead acid due to current draw and whatnot and priced at $540 for 12v 100ah
