Abstract

To reduce using of unrenewable energy for electricity generation, required alternative energy instead. In addition to making a reduction in the use of labor so that they can save operational costs incurred. In order to explore forms of alternative and clean energy sources, solar energy get big attention. In fact the sun's energy is the energy source that availability is not limited. To get the electricity that comes from the sun, we need a solar panel so that light energy from the sun can be turned into electrical energy. A 50WP solar panel produced electrical energy ± around 17Volt and cash flows of ± 1.6 Ampere. So to get the appropriate voltage for the 12 Volt battery required a series of buck converter. The maximal current charging using battery charger circuit is 0.32 Ampere so the charging time about 37.5 hours. The vurrent input in inverter reach 4 Ampere and the current output is 3,8 Ampere with 50W water pump load.
