Open box and unused. Still in box see photos. box may have some wear/tear Pikasola Wind Turbine 200W max 220W 12V 5 Blade Wind Vertical Axis Generator 3 Phase AC Permanent Magnet Generator Wind Turbine Kit with Controller for Hybrid Wind Solar System 5-leaf double-axis vertical blade design, which looks like a Red lantern. Safety factor is high due to blades be fixed inside by a flange, then not risk of blade falling off. Wind blades adopt reinforced fiber nylon which more durable and strong ability of Anti-wind. Especially with optimized aerodynamic shape and structural design, has a High wind energy utilization. Wind turbine can start by breeze and adapt to 360 wind, no yaw system is needed. The vertical wind turbine is quieter than horizontal axis turbine. Double bearings make it more stable and not easy to shake when wind generator is running. Silent rotation, suitable for home, boat, marine, monitoring use, solar and wind hybrid street lighting system. Permanent magnet three-phase alternating current can reduce the resistance torque of wind generator effectively. Also make the wind wheel and the generator matching better and then running more reliability
