For example, a battery cabinet contains 16 pcs of 12V battery, and all of them connect in series, the nominal voltage of this battery cabinet is 192Vdc. It would match the UPS which should connect 16 pcs of battery, battery voltage 192Vdc or charging voltage 218.4.
One cabinet should be able to hold at least one complete string of cells. Best practice is that strings should not be split between two cabinets in order to ensure reliability of the entire string. Figure 1 - Battery cabinet with top terminal cells A battery disconnect switch should be located as closely as possible to the end of a string.
Battery Capacity in Ah = (900Wh x 2 Days x 3 Hours) / (50% x 12 Volts) Required Size of Battery Capacity Bank = 999 Ah (Almost 1000Ah) This is the minimum battery bank capacity size you need to run a 900Wh load daily for 3 hours.

Spaces about stationary standby batteries shall comply with 110.26 and 110.34. Working space shall be measured from the edge of the battery cabinet, racks, or trays. For battery racks, there shall be a minimum clearance of 25 mm (1 in.) between a cell container and any wall or structure on the side not requiring access for maintenance.
Generally speaking, the larger the battery (both physically and ampere-hour rated), the more likely a rack configuration will be considered. There are no hard and fast rules, but typically once a battery unit (single-cell or multi-cell) gets above 100 AH, it favors rack-mount. Below that, cabinet mounting should be considered. Number
Additional cooling is rarely required for a battery cabinet, but the cabinet must have (1) unobstructed paths within the cabinet for hot air to rise, and (2) adequate openings for hot air and hydrogen gas to escape into the room.

the battery has capacity 160Ah and lifecycles are counted on 0.3C - for such many lifecycles (how many times you can charge and discharge it before it wears to bad) you can get 160A*0.3 = 48A for 160Ah/48A = 3:20 hours (aprox), at 3.2V it is 153W, so you need 8200 / 153 = 54 such bateries for optimal use (and 3 hours cycle).
