31. Step Process Example 1 Identify total daily use in Watt-hours (Wh) 6,000 Wh/day 2 Identify Days of Autonomy (backup days); multiply Wh/day by this factor 3 Days of Autonomy: 6,000 x 3 = 18,000 W 3 Identify Depth of Discharge (DoD) and convert to a decimal value. Divide result of Step 2 by this value 40% DoD: 18,000 / 0.4 = 45,000 W 4 Derate battery bank for ambient temperature effect. Select the multiplier corresponding to the lowest average temperature your batteries will be exposed to. Multiply result from Step 3 by this factor. Result is minimum Wh capacity of battery bank: Temp. in [degrees] F. Factor 80+ 1.00 70 1.04 60 1.11 50 1.19 40 1.30 30 1.40 20 1.59 60° F. = 1.11 45,000 x 1.11 = 49,950 W 5 Divide result from Step 4 by system voltage. Result is the minimum Amp-hour (Ah) capacity of your battery bank. 49,950 / 48 = 1,040 Ah
