Superwind SW 350-II Silent 48V wind turbine – 350W

superwind SW 350‑II Wind Turbine – 48V Model: Total Autonomy for Sailing Boats

The excellence of marine wind energy: Silent, Robust and High Performance

The superwind SW 350‑II 48V is much more than a marine wind turbine: it is a professional-grade autonomous power unit designed to offer absolute reliability in the most hostile environments. Manufactured in Germany, it incorporates patented innovations that make it a benchmark for cruising yachts and industrial applications.

1. A specific 48V production unit

Unlike "multi-voltage" products that make compromises, the superwind SW 350‑II 48V is a technical entity in its own right.

• Dedicated winding: The generator is specifically wound to optimise the charging of 48V DC battery banks, ensuring maximum efficiency even in light breezes.
• Real performance: This dedicated design avoids the efficiency losses associated with universal systems and ensures a perfect fit with your vessel's electrical architecture.

2. The Star Hub and patented blade adjustment: Absolute safety

The heart of superwind's technical superiority lies in its high-performance hub, the Star Hub. It houses the patented rotor blade adjustment system, a crucial innovation that sets superwind apart from all its competitors:

• Pitch Control Mechanism: Unlike low-end wind turbines that use magnetic braking (causing overheating) or simple de-winding, superwind adjusts the angle of attack of its blades mechanically. As soon as the wind speed exceeds safety limits, centrifugal force activates the mechanism inside the Star Hub to reduce wind resistance.
• Active storm protection: This system is 100% autonomous. In the event of a violent gust or storm, the rotor slows down on its own without any human intervention and without engaging the on-board electronics.
• Uninterrupted production: Where other wind turbines must be shut down or short-circuited to prevent destruction, the SW 350-II continues to rotate and produce energy safely, even in storm-force winds. It never stops when you need energy the most.
• Passive safety: No fragile electronic sensors are used; regulation is 100% mechanical and synchronised in the Star Hub.

3. "Silent Power" rotor blades and acoustic comfort

Noise is often the weak point of wind turbines. superwind has solved this problem with its "Silent Power" blades:

• Silent Power aerodynamic profile: The blades are made of a high-tech composite material, with precision profiling that minimises turbulence at the blade tips. The result: the characteristic whistling sound of traditional wind turbines disappears, leaving almost total silence, even at high speeds.
• Yaw damping: Conventionalwind turbines "clap" or vibrate when they change orientation in response to shifting winds. The superwind incorporates an internal pivot damping system. This damped wind tracking ensures that the unit aligns smoothly with the airflow, eliminating mechanical shocks and annoying pivoting noises when moored.

4. Integrated structural noise decoupling: Invisible comfort

The major problem with wind turbine installations on sailing boats is the transmission of vibrations through the mast, which turns the hull into a "sound box".

The superwind SW 350‑II is designed to be "transparent" on board the yacht:

• Frequency absorption: The SW 350-II incorporates a structural noise decoupling system. Silent blocks and high-performance insulating elements are inserted at the very heart of the connection between the nacelle and the support.
• Total vibration isolation: This decoupling prevents high-frequency micro-vibrations generated by the motor and rotation from reaching the mast. This ensures that no resonance is perceived inside the boat, allowing you to sleep peacefully while the wind turbine recharges your batteries.

5. The superwind ecosystem: The vital integration of accessories for a complete system

For an installation that complies with superwind GmbH's warranty standards, the wind turbine must be designed as a complete system. The use of original accessories is not optional: it is the key to reliable and sustainable energy management.

SCR Marine charge controller (48V)

The brain of the installation. Manages the charge via a shunt and diverts the excess to resistors to protect the stator.
