Rancang Bangun Alat Cas Batere 10a Buck Booster Dc Ke Dc Konverter Tenaga Sinar Matahari Berbasis Atmega328

Abstract

The use of solar power as a renewable energy is increasingly being used, solar power produces environmentally friendly energy by converting sunlight into electrical energy using solar panels. The electric power generated by solar panels depends on the intensity of sunlight and the working temperature of the solar panels. Weather conditions and the position of the sun are always changing, making the output power of solar panels fluctuate and do not always remain at maximum power conditions. Therefore we need technology that can regulate the function of charging the battery and releasing current from the battery to the load. Therefore,An experiment of buck booster solar cell charger controller has been done and the prototype had been built. The fluctuation of the sun's shine energy can be anticipated by a buckbooster chip XL6009 in order to produce a constantvoltage output of 15.1 volt. The change in feeding current to the battery just prolonged the time of charging, but in average the battery is fully charged in 5 hours. A current booster is needed in parallel to the buck booster in order to use the solar charger controller to charge a bigger batteries,anyway, the arduino uno is used to check and to stop charging, whenever the charging voltage reached the specified voltage, in this experiment 14.8 volt is reached to stop charging.
