Your best bet with batteries is to get something of better quality than you would find in walmart, (Rolls-Surrette is my preference) But if you rarely have power outages, the best deep cycle marine battery would do. The battery life is going to largely depend on the environmental and charging conditions. Insulate it from extreme heat and cold, and use a quality charger like iota. For monitoring I would suggest the BND http://www.remotemonitoringsystems.ca/ which will give you a number of inputs, outputs, and SNMP query. I have built a small circuit based on the allegro acs750 http://www.allegromicro.com/en/Products/Part_Numbers/0750/index.asp to report current draw where it is important to monitor in remote sites. If you are running 48v and 24v from the same battery bank you are liable to create a load imbalance that will decrease the life of the batteries. I prefer to run everything from DC, keeping the load down and the signal clean. I haven't ever found a solution in a box that suits my satisfaction for peace of mind, quality and features. Steve
