Samrey Wren 300 watt battery chargeing package

Samrey Wren Micro wind turbine features:
Low TSR rotor blades with excellent low wind speed performance, and exceptionally low acoustic emissions. Rotor blades are injection moulded for excellent consistency.
Rated at just 8m/s for superb low wind speed performance. A samrey Wren Micro wind turbine will generate more kWhs at low wind speeds!
Proprietary low inertia axial flux generator using Neodymium Iron Boron magnets. Our unique ironless generator design has no ‘cogging’, which allows effortless start up in low winds and reduces ‘generator hum’. The 3-phase output from the generator is rectified onboard for a DC output.
CNC machined components throughout.
Constructed from powder coated / anodized aluminium and stainless steel.
Aesthetically pleasing and low visibility profile.
Mercury free yaw slip-rings prevent the output cables from becoming twisted as the turbine tracks the wind
Oversized tail fin for excellent response to turbulent wind conditions
Designed to run through severe weather conditions
Unique bearing configuration resulting in low friction, low bearing noise. All bearings a lubricated and sealed for life
Anti-vibration fixings used throughout.
All-up weight of just 5.5kg
Optional nose cone

The samrey Wren Micro wind turbine is small direct drive micro-turbine designed for use in many difficult and demanding applications. Its aesthetic low profile design, coupled with its unparalleled low wind regime performance and low rotor acoustics make this turbine the ideal choice – whatever your application – From electric fencing to CO2 abatement or off-grid homes.

The samrey Wren Micro wind turbine features a fully integrated 3-phase Permanent Magnet Generator (PMG) that takes advantage of Neodymium Iron Boron magnet technology. This configuration gives the PMG excellent low RPM characteristics with a very low cut-in speed allowing the turbine to spend more time generating power.

The uniquely designed and manufactured turbine blades work in harmony with the PMG to allow the turbine to operate at low wind speeds, low RPM and with low acoustic emissions.

Of equal importance, is the Wren’s ability to run at high output during ‘big’ winds for prolonged periods of time with out need for mechanical or electrical ‘cut-outs’. This means that a Wren Micro-turbine will generate more kWhs in an average wind regime -compared to competitor products that are ‘rated’ at an unrealistic 12m/s (27mph).

The samrey Wren Micro-wind urbine has two modes of operation. The unit may be used charge deep cycle battery banks at 12 or 24 Volts DC, which can later be converted to mains AC with use of an inverter or directly run low voltage lighting. Alternatively the samrey Wren Microwind turbine is available with a battery-less grid tie inverter that will allow the turbine to be linked directly to an AC ring main without needing any battery storage. The power generated will offset power that you would normally pull off the grid. The Wren Micro-turbine can also work hand-in-hand with photovoltaic panels to ensure that power is being generated in all weather conditions.

The samrey Wren Micro wind turbine will operate most efficiently when it is mounted high above obstructions in free flowing laminar airflow. Wren may also be roof mounted – But as with any roof mounted wind turbine, performance may suffer due to the inherent turbulence present at rooftop level.

In optimum conditions, with an average wind speed of just 5 m/s (11mph), a single Wren Micro-turbine could generate as much as 40kWh per month of free and clean renewable energy. That represents a CO2 abatement of 18kgs per month.

If just 1000 samrey Wren Micro wind  turbines were in service, a potential 216,000 kgs of CO2 emissions would be prevented from reaching our atmosphere in a single year. Our larger products, Mistral & Merlin, have exponentially greater power capacity and will be able to make a significant or total contribution to your power requirements.

As worldwide energy prices continue to increase, the financial incentive to install a micro-generation system will become very significant!
