Introduction[edit]

Describe what battery capacity means in this context.

Tables[edit]

Table 1 shows the temperature multipliers for several different batteries at different temperatures.

Temperature multipliers are used when calculating the correct battery size of a solar photovoltaic system. The temperature multiplier for the battery is multiplied by the depth of discharge (DoD) and amp-hour (Ah) demand to obtain the needed battery storage of your system. These values were obtained from 3rd and 4th Edition of Thomas B. Reddy's Battery Handbooks, [1], and [2].
