Abstract: Energy saving in homes can be reached thanks to optimized energy management. This paper deals with the case of a solar house, installed on the site of UDES in Bou-Ismaïl (Algeria) located in the south shore of the Mediterranean, which is used as a test bench for the developed energy supervision system. The house is powered by an on grid PV system with backup. The proposed supervision system looks for the optimal flow energy management taking into account the availability of the PV energy, the state of charge of the batteries and the energy demand of the loads while promoting the self-consumption and reducing the exchange of energy with the grid. The simulations of the monitoring system operation were carried out over a period of one year in order to match the energy demand with the local PV production using real daily consumption of the loads. It has been found that the storage improves significantly the local photovoltaic energy consumption by about 28% in winter, 95% in spring, 45% in summer and 42% in fall for the studied PV system (3.2kWp, 12kWh). This study has shown that there is a strong overall potential for improving self-consumption through the optimal management and storage of energy in the climatic conditions of northern Algeria.
