Grid-Connected Hybrid Wind and Solar Power Systems
Home wind turbine power systems come in two main types: grid-tied and off-grid, each using different inverters.
A grid-tied system connects to the grid via a step-up transformer, allowing all wind-generated energy to be exported to the grid.
An off-grid system, used in homes not connected to the grid, stores all wind-generated energy in a battery. The off-grid inverter converts the battery's DC current into AC current for household appliances. However, these systems have a limited battery storage capacity, which may interrupt appliance operation when the energy is depleted.
Additionally, a third configuration is possible by replacing the off-grid inverter with a hybrid inverter, which can also connect to solar panels and the grid. This setup can import energy from the grid if the demand exceeds the battery's stored energy, offering a more reliable energy supply.
