The present invention relates to an IoT based control system of a photovoltaic power generator for each module string of multiple circuits which provides an IoT based monitoring system with respect to each control point. More specifically, an IoT based control system of a photovoltaic power generator for each module string of multiple circuits can improve a rate of photovoltaic power generation by matching voltage with respect to a maximum power point of a circuit module for each string by maximizing usability of a module which can generate, when a problem of degrading the rate of photovoltaic power generation of each circuit such as a weather change of cloud, snow, and rain, etc., and a partial shade by subject shade, aging of the module, contamination by bird excretion, fallen leaves, dust, abnormal of the module etc. generates. The IoT based control system comprises: a string; a voltage measuring part; a current measuring part; an average value calculating part; a deviation value calculating ...
