How to calculate battery capacity for ups. It stands to reason that the bigger the load that one wants to support the greater the capacity of the batteries should be. Load 1000w can be calculated using our previous guide here or it can be max ups capacity ups input 24v. Looking at the capacity we see that the required wattcell is too much for one bank.
Quantity of batteries per bank 48012 40 batteries. The ups battery bus voltage is 480 v. Ups battery size runtime calculations.
Required runtime 15 hours. In our example. As in point 1 above the longer the required runtime the greater the battery.
Number of cells per bank 40 x 6 240 cells. The typical table is for 12 v batteries six cells of 2 v each.
