The AiR30 is designed for charging small battery banks in off-grid scenarios such as for small cabins, RVs, camping sites, garden lighting, educational demonstrations and hobby fun. This new generation of the Air-X wind turbine from Southwest Windpower also serves ideally in small hybrid systems with solar. Not to be used in marine environments (see our Air Breeze instead), it comes with a 5 year warranty. Made in the USA.
