Rancang Bangun Pembuatan Sistem Charger Menggunakan Buck Boost Konverter Pada Sistem PLTS

Abstract

Currently, the use of renewable energy is unavoidable and is encouraged to exploit it on a large scale with the aim of minimizing the use of fossil energy. Fossil energy that is getting depleted and non-renewable can only be used as backup energy when new renewable energy is being developed because renewable energy still has many weaknesses and shortcomings. Renewable technology in the form of PLTS. PLTS converts sunlight energy into electrical energy. Electrical energy is stored in the battery. The result of the conversion that has become DC electricity is then regulated by the Buck-Boost Converter. PLTS Energy Utilization is offered technology for setting up an Arduino microcontroller charger, namely knowing whether or not the charger system is active. When the battery is full, the current will be stopped. And if the battery charge is empty then the battery load cannot be used. To stabilize the voltage into the battery used Regulator LM317. To regulate the input voltage remains constant by regulating the voltage. If the input voltage is too low below 12V DC then the regulator will increase it and if the voltage is too high the regulator will lower it where the regulator output voltage will be compared to the reference voltage, namely the setpoint voltage if the voltage is stable. The voltage is set to reach 12-14V DC. Battery also emits electrical energy to the Arduino Uno 328. To read the current and voltage from the solar panel through the Arduino Uno, see the LCD.
