Abstract
Sunlight makes it possible to adjust scale of electric power easily as a electric energy without air pollution. Solar cell to convert the sunlight to the electric energy has DC output which is influenced on temperature and irradiation time. Conversion of DC output from the solar cell to AC is necessary due to the fact that most loads to be used currently are compatible with AC generally. In the present work, Two-phase chopper system with two seperate groups to obtain two identical DC is used to preserve the energy from the solar cell in two battery. They are controlled to be operated around maximum output of the solar cell under the condition of constant voltage. Photovoltaic system with DC
