Global energy demand and the rapid depletion of fossil fuels have significantly increased the need for renewable energy sources (RES) such as solar photovoltaic (PV) panels. These developments have led to the widespread use of microgrid networks with hybrid power systems (HPS). This study analyzed the technical, economic, and environmental implications of optimal inverter sizing in hybrid power systems with PV panels installed in microgrids. In particular, the system sizing and economic impacts of changing the optimal PV-inverter capacity (DC/AC) were evaluated using optimization analyses in the case of İstanbul. In addition, sensitivity analyses were carried out, considering the constraints on energy sales to the grid and the targets for increasing the share of renewable energy. The results showed that the inverter load was 1.52 in the optimal scenarios. This ratio increases to 1.99 when there are constraints on energy sales to the grid. In addition, it was observed that although the share of renewable energy approached 95%, the annual capacity utilization of the inverter was only around 31%. The findings underscore the necessity of determining the optimal inverter capacity to enhance economic efficiency and system performance.
