What happens if the wind turbine is generating more electricity than is being used at that time?
If your system is grid-connected, the electricity will be fed back to the mains. Grid-connected systems use an electrical rectifier and inverter combination to generate grid-synchronised electricity so they can be connected to the mains. There are no batteries. A stand-alone system has batteries which will be charged by any excess electricity that you generate that you are not using at the time. When these batteries are fully charged, excess energy is discharged via a dump load (generally a resistive heater) to prevent damage to the generating equipment or batteries.
