400W 12V wind turbine with 5 blades

This 400W 12V wind turbine provides a reliable source of electricity for all types of off-grid applications. This turbine is designed for use in a wide range of locations with varying degrees of wind speed. For example, in high wind areas such as open fields, coastal areas, and high ground, as well as in low wind areas when raised on a suitable pole. It is suitable for both stationary applications (remote, off-grid, backup) as well as for mobile use (e.g. boats).

This wind turbine is also the perfect addition to any solar charging kit to supplement energy production (particularly useful for charging at night time or in countries with reduced winter sunlight).

Key features

This 400W 5-blade wind turbine is expertly designed to provide stable and reliable power with high efficiency in low wind conditions. Important characteristics include

- Robust design: The casing of this turbine is made of strong cast aluminium alloy to ensure long-lasting use in harsh conditions whilst maintaining a rapid response to incoming wind.

- 5 blade construction: Maximises output in poor wind conditions and reduces the minimum required wind speed for start-up to only 2.5 m/s.

- Aerodynamic optimisation: The blades are optimally shaped for maximum efficiency and protection from strong winds.

- Automatic wind detection: The tail vane automatically seeks out the best wind direction and re-orients the turbine accordingly.

- Patented permanent magnet AC generator: Features a special stator for effortless operation with minimal blade resistance.

- Adjustable tube connector: Suitable for a wide range of mounting poles, including those typically used for scaffolding.

- Easy installation: Assembly of the turbine is extremely straightforward and requires minimal effort.

A dditional considerations

The maximum output of this wind turbine is not strictly limited to a specific power rating. Although this wind turbine is rated to produce 400W at a wind speed of 10 metres per second, when exposed to strong winds it has the potential to exceed its nominal rating.

This wind turbine produces three-phase AC output and therefore requires a triple wire connection to a suitable charge controller .

A suitable pole for mounting is required (not included). Pole recommendations can be found in the Installation tab.

Installation and assembly of this wind turbine is extremely simple. For further information, please refer to the detailed user manual supplied with this product. Please note: The picture above and component list in the user manual are not entirely accurate and shows a different connector type to the tube connector which is supplied.

Please note that this wind turbine requires connection to a suitable charge controller in order to charge a battery.

This wind turbine requires a mounting pole, which is not included. The base of the wind turbine features an adjustable tube connector (diameter 60mm) which can be expanded to accommodate a wider pole or secured around a narrower pole using bolts and additional holes. We recommend using a metal pole for mounting (e.g. a scaffolding pole) rather than poles made of timber or plastic, which may pose a safety hazard.
