Membuat Genset Switch Otomatis Pengganti Aki dan Inverter

Membuat Genset Switch Otomatis Pengganti Aki dan Inverter


        Pada kesempatan kali ini saya akan membahas mengenai bagaimana cara membuat sebuah alat yang memadukan antara sumber dari aki dan sumber dari genset, prinsip kerja alat ini yaitu terdapat solat panel atau PV (photovoltaic) yang akan mengisi battery aki, tegangan DC aki kemudian dikonversikan ke AC menggunakan inverter untuk menghidupkan lampu AC dan lainnya, jika aki sudah habis maka akan switch otomatis ke genset, jadi genset akan menyala dengan sendirinya tanpa bantuan petugas jaga, sehingga akan lebih cepat dan efisien. yang perlu diperhatikan yaitu mekanisme dalam menghidupkan genset, karena akan ada step CHOOKE dan RUN saat Knob Stater On. Untuk lebih jelasnya berikut adalah skema dan programnya.

b. Sensor Arus ACS712





c. Sensor Tegangan AC ZMPT101b






d. Mekanisme Genset









e. Program Arduino IDE
