Magnum M77. Built once. 25 years of power.
Meet the power monster — MAGNUM: the world's leading horizontal wind turbine generator for homes, vessels, and off-grid sites. Trusted at the Arctic Discovery Research Centres, on California's finest homes, and aboard Maersk and MSC fleet ships.
Power & Performance
- Peak output: 10 kW in strong winds (22+ m/s)
- Rated output: 3.5 kW at 15 m/s sustained wind
- Generates from: 6 m/s wind speed
- Daily energy yield: 3–25 kWh per day depending on site
- Annual yield: 2,500–9,000 kWh depending on average wind
Inside the Magnum — Industrial-Grade Engineering
The motor inside Magnum is genuinely 15 kW continuous-rated — 50% more capacity than typical 10 kW competitors. This headroom protects the generator from gusts and dramatically extends service life.
- 24-pole permanent magnet generator with NdFeB N42 super magnets (60×25×5 mm, nickel-coated, bread-shape)
- Skewed magnet mounting — reduces cogging torque by ~80%, smoother torque curve and longer bearing life
- 4 kg of pure copper winding, 90 turns per stator slot
- Class 200°C high-temperature enameled wire (IEC 60317-13 GR 2) — the same insulation grade used in industrial servomotors and EV drivetrains, certified CE / UL
- ±0.05 mm precision tolerances across all machined components
- 2.35 m rotor diameter with aerodynamically optimized aluminum blades
- Self-furling design protects against storm winds above 25 m/s
- Generator dimensions: stator 16 cm × 12 cm (2.4 L volume); 24 magnets at 60×25×5 mm = 180 cm³ total; rotor 2.35 m diameter, 4.34 m² swept area
How power is calculated
Available wind power follows the formula P = ½ × ρ × A × V³ × Cp × η, where wind speed (V) is cubed — small increases in wind speed produce dramatic increases in output. Magnum's power coefficient (Cp) reaches 0.42 under ideal conditions thanks to its blade aerodynamics and skewed magnet design. Combined with 92% electrical efficiency, Magnum extracts ~39% of available wind energy as electricity — among the highest figures for small horizontal turbines.
Designed and manufactured in Europe

Product Features
Meets the daily electricity needs of most households with 10 KW power.
TESUP Magnum generates 10 KW of power standalone, capable of meeting daily household electric needs.
Durable and Resistant to Weather Conditions
The corrosion-resistant carbon fiber body is capable of operating at extremely cold temperatures, down to -50°C.
Rotation at Low Wind Speed
Rotation starts at a wind speed as low as 3 m/s, and from there, it continues spinning smoothly and effortlessly thanks to its large wind-catching surface area.
Easy and Quick Installation
The product can be installed in just around 40 minutes. Watch how to do it by clicking the link.
Double the Power
It can also be combined with TESUP solar panels for optimal energy production.
Sell to the Grid
The electricity generated by Magnum can also be sold to the grid by using an inverter.
2 Year Warranty
The product comes with a 2-year TESUP Care Product Warranty, providing peace of mind and ensuring that your investment is protected.
How to Use
Please keep in mind that the wind turbine needs to be installed following the user manual which can be found in “The Book by TESUP”and under ideal weather conditions to reach its maximum power generation potential.
This product is compatible with connection to the electrical board at various output power settings. However, it may only be connected to a power socket after the necessary adjustments in accordance with country-specific regulations have been made.
