The use of electric vehicles (EVs) is growing rapidly and widely, as they produce no gas emissions, reduce pollution, and do not rely on fossil fuels. Solar energy is a reliable and renewable energy source. Problems arise when charging stations cannot meet demand due to unfavourable weather conditions. This research offers a solution using multi-source energy management to ensure the availability of electrical energy sustainably and economically. The multi-source inverter converts from direct current (DC) to alternating current (AC), stabilising the voltage from solar panels, batteries, and the grid. The proposed energy management ensures an uninterrupted power supply, especially when energy absorption from the sun is reduced due to weather. The research contributes to providing and managing energy for electric vehicle charging, prioritising the exploitation of energy from solar panels and batteries. Sourcing electricity from the grid will be the last resort when the load reaches its peak. With the proposed strategy, the charging station can reduce the use of fossil energy, requiring only 1,795 watt hours (Wh) each week.
