Vertical Wind Turbine ElvWiS II ALUMINIUM Hybrid (190 W)

Two-stage quality wind turbine with Savonius rotor (assembly kit)

Turbine components disassembled, generator fully assembled. Complete stainless steel assembly material is included.
With double-disc generator GEA-400-VA and universal mount.
Protection against theft by screwing the components.

Optional with 3-Phase rectifier or 12/24-Volt charge controller.
Optional upgrades for particularly demanding locations: Ceramic bearings and/or reinforcement angles on the mount.
(Easily, you can choose the options beside the article images above in the variant configurator.)

This turbine is a hybrid of the ALUMINUM and ADVENTURE series, which combines their proven advantages:
- Large, solid rotor made of lightweight and durable aluminum.
- Stable and torsion-resistant stainless steel hollow axle in the rotor.
- Practical plug-in mounting of the rotor in the generator and upper bearing support.
- Effective bolt connection between rotor and rotor axis.
- Easy adjustment in the upper bearing by floating mounting.
- Massive stainless steel ball bearings in generator and mount.
