Off Grid Telecommunications Plant Battery Project

I have the opportunity to get about 18 of the EnerSys 2GU-13 Batteries used for Central Office Telecommunications Backup. The Batteries are Flooded Lead Calcium Flat Plate, Styrene Acrylonitrile Copolymer case, 4V with (4) Cast Lead Post terminals [Capacity @ 8hr Rate (Ah): 1220 (c8), .]12.4"L x 15.1"W x 27.3"H (max ht), 436 Lbs.
Battery Features
Question : Could this be a alternative battery backup source that's a bit more advance than Lithium? Would you recommend this for full off grid configuration due to the 1230 ah? Do anyone want some of these batteries if I have extras left over once the Solar configuration is complete? My ideal is to get 12 of these total. Setup 4 banks of 3 in parallel to equal 12 volts then series these two bankes to make 24 Volts the series those two to make a 48 Volt Giving me 14640 ah. for the off setup.
Battery Features
High Rate Performance - Copper inserted posts assure efficient high rate
performance with minimum connector re-torquing requirements
• Life - The battery has an expected design life of 20 years at 77˚F under float service
• Loads - The battery is designed to handle complex load profiles requiring high load
currents as well as long duration discharges
• Construction - Cover made from Flame Retardant PVC (UL94-V0/L.O.I.32%) as standard
• Application - The battery is ideally suited for power plant, power switching
and standy power applications
• 100% initial capacity

Having 12 in series will provide 48V nominal at their rated capacity, not quite sure what your theroy is regarding parrallel series is, but what I can say is you'll need sufficient charging capacity to recharge depending on discharge levels.This is a common mistake, having a battery capacity greater than the charging ability, it would be useful if you could provide information on how you intend to charge such a large capacity bank.
