The Viking wind turbine is compatible with stand-alone systems where the turbine delivers the energy production to a unit without being connected to an electrical grid. A stand-alone energy solution offers the wind turbines situating in areas, without access to an established electrical grid or at places, where coupling to an electricity supply meter and any added subscription, is economically unsustainable. Instead of connecting to the electrical grid, the production from the turbine is stored in battery banks or the turbine runs parallel with a diesel generator. There the electricity will be converted, being spendable for various electrical devices.
