A water electrolytic system includes a water electrolyzer, a photovoltaic generator which is a power source for the water electrolyzer, and a DC/DC converter adapted to convert the maximum output from the photovoltaic generator into a current and a voltage corresponding to an IV characteristic of the water electrolyzer by converting current and voltage for a portion of such maximum output, and to input the converted current and voltage to the water electrolyzer. With the water electrolytic system, even when an optimal point of operation of the photovoltaic generator, i.e., the maximum output from the photovoltaic generator has been varied, the efficient operation of the water electrolytic system can be carried out utilizing such maximum output.
