For best performance, use heavy cabling and short cable runs. Designing to allow no more than 5% voltage drop (so the controller works properly) cable should be as follows: 4mm2 - max length 7.7m 6mm2 - max length 11.5m Great for off grid sustainable power generation. . Price does not include controller. Wind turbines must use a wind turbine controller to convert the 3 phase 12V AC to DC, and to apply a load (braking) when the battery is full. Simple PWM controller $79 Simple MPPT controller $129 MPPT advanced hybrid controller with LCD with 300W solar, PC interface $420 Nominal voltage 12V Start-up wind speed 2.0m/s Rated wind speed 13m/s Survival wind speed 50m/s Wind wheel diameter 1.30m Blades quantity 5 Blade material Nylon fiber Generator Permanent magnet synchronous generator AC 3 phase output Controller system Electromagnetic Regulating way Automatic adjustment as per wind direction Working temperature -40°C~80°C Turbine uses a flange mount. A blank flange is supplied to weld to your tower tube for easy mounting. We also sell a tower to go with this turbine. We can also supply 24V 3 and 5 blade turbines, and 48V 800W 3 blade turbines. Pickups are from Johnsonville. We use Aramex for delivery of small items, please check that they do not regard your address as rural.
