Abstract

Battery is an energetic collector of solar cell system. Battery which is used in the system must have many qualities in the followings. The battery must be "Deep Cycle Battery" type. In addition, the battery is Cleary indicated the percentage of DOD. The indication of DOD is used for calculation other valve used in solar cell system. Currently, the percentage of DOD of battery is fixed by battery manufacture. If users would like to calculate is introduced % DOD, the users have to check the battery at least 12 months. This article is introduced battery deep of discharge meter by using theory of lead acid battery under deep cycle type and including the theory of DC. Current and internal resistance of battery. The data used for analyzing are collected according to the theories. The data will be calculated by monitor unit and controller systems.
