This application provides a power supply method, device, system, medium, and product for a photovoltaic thermal energy storage system, relating to the field of photovoltaic power generation. The method obtains the state of charge (SOC) of the energy storage system and the output capacity of the shared bus capacitor inertia. When the energy storage capacity is sufficient and the bus inertia support capacity is normal, multiple power sources are used to power the system.
