Off-grid system:Wind generator + batteries + inverter = 230 V. Batteries can be expensive but independency provided in exchange.
Grid-tied system: Energy produced by wind generators can also be delivered into the grid. This solution requires no battery bank but an intelligent controlled, more expensive inverter should be integrated that amplifies the energy from the turbine and directs it into the grid. (“It boosts the grid”.) In this system the traditional electricity meters are replaced by a so-called “back and forth” balance meters that measures the quantity of consumed and regenerated kWh the difference of which makes out the sum of utility bills. Dependency is the only disadvantage of the system.
