To optimize battery charging, the author will create an optimization tool that uses a buck converter. The buck converter converts the initially high voltage to low, to make the tracking point more optimal. In this study using a 24V system voltage with a battery capacity of 200Ah, and a solar panel with a capacity of 400Wp, from the results of tests carried out the peak power produced by the system was 238,1 watts with a current of 9,38. in these results the addition of a buck converter resulted in an additional power of 8%, with a total energy of 1142 Wh resulting in an increase in efficiency of 10.9%} }
