If it were me, and assuming I truly needed that storage capacity (hint - are you sure you need so much?), then I would go with a forklift battery. I understand a company called GB Industrial Battery can provide a 1200 amp hour 24 volt battery for $3400 delivered in the 48 states. They will also pickup a discarded battery free of charge (being compensated with the recycle scrap value of the discarded battery, of course - which is good as you know they're going to recycle what they can since their compensation depends on it). In theory, you could have a battery delivered every 10-15 years (the expected life for such a battery in the off grid application) and have the old one carted off for recycling. I would get the dimensions of the battery you want delivered, then build a heavy duty platform with casters that will allow you cart the thing where you need it (battery would be 1500 pounds and with a 20" by 30" base, and height of 22"). Check with the company to see if they can place the battery on the cart without difficulty.
