Gel batteries are so strong should they be put in a big battery bank with less load where they won't be drained to less than 50% of its capacity. My boss has 6 batteries on a 48v inverter that powers a borehole pump, 4 fridges, all lights, geyser , booster pump, washing machine. All these does function during the night but leaving 95% during the morning. I would go for them if I had appliances that consumes much.
