Vertical axis wind turbine, models SJ1500, SJ2000, SJ3000. Compact permanent maglev generator for alternative energy applications where low startup wind and quiet operation are required. Key benefits Reliable offgrid power: three phase permanent magnet suspension motor delivers steady output for battery charging and DC loads at 12 V, 24 V, or 48 V. Starts at low wind speeds: captures usable wind energy in locations with light winds to extend energy availability. Compatible and compact: vertical axis design allows omnidirectional wind capture and flexible mounting between 2 and 12 meters . Stable electrical output: power tracking intelligent microprocessor control regulates current and voltage for more consistent charging. Durable construction with manageable handling weight: aluminum alloy diecast shell and double bearing seat for improved structural strength; unit weight less than 21 kg. Features and specifications Models: SJ1500, SJ2000, SJ3000 Type: Vertical axis wind turbine Generator: Three phase permanent magnet suspension motor Control system: Electromagnet and intelligent microprocessor tracking control Blade quantity and material: 2 blades, fiberglass Shaft material and type: iron shaft, vertical axis configuration Voltage options: 12 V, 24 V, or 48 V Mounting: supplied without mounting base; suitable for tower or pole mounts at 2 to 12 meters Protection grade: IP54 Operational limits: works at relative humidity up to 90 percent and at altitudes up to 4500 meters Wind ratings: low startup wind speed; designed for continuous wind speeds up to 40 meters per second Protection systems: overspeed protection via electromagnetic brake; overload protection via electromagnetic brake and unloading unit Size and handling: compact form factor, low vibration and low noise; lanternlike appearance for discreet installations Practical applications Home offgrid systems: charge battery banks for lighting, small appliances, and backup power in cabins or rural homes. Marine and boat power: supplemental generation for boats and offshore structures at 12 V or 24 V installations. Street lighting and surveillance: power LED street lamps, security cameras, and remote monitoring equipment as part of a hybrid solar and wind solution. Installation notes Mounting base not included; select a suitable pole or support structure for the specified mount height range. Ensure site winds and mounting meet the up to 40 m/s continuous wind rating and altitude and humidity limits. Routine inspection and maintenance of bearings and electrical connections will help preserve performance. This vertical axis wind turbine provides a compact, lownoise option for smallscale wind generation where simple, durable equipment and lowstartup performance are needed.
