Abstract :Wind and solar energy hold an important position in renewable energy sources. In wind energy conversion, the output power can change depending on the speed and intensity of the wind while in solar energy conversion it can change depending on the solar radiation and temperature. The energy conversion that combines these two energy types is called hybrid system. The energy produced by the wind and PV, hybrid power systems shows variance depending on the speed and intensity of wind and irradiation and temperature of PV panels in some cases the wind power and the PV power may not be at the expected level for the on grid micro inverter. This study aims to increase energy sustainability on grid based the hybrid power systems. The hybrid power system’s output voltage is constantly measured with a voltage sensor. The input voltage range of the micro-inverter has been tried to be kept at a value that can give energy to the grid. In order to achieve this, the energy continuity is increased by providing battery support at voltages close to the minimum power value that will enable micro-inverter conduction.
