Wren and Mistral Wind Turbines
See the bottom of this page for Prices
The Wren Micro-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 Wren Micro-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.
WREN MICRO TURBINE Truly low wind-speed operation. The Wren is
rated at only 8m/s instead of the
typical 12m/s. This means more kilowatt-hours from average wind
regimes.
-Low TSR rotor blades giving excellent
performance and very low noise emissions.
- Proprietary 3-phase alternator design that
operates at low RPM. The WrenMicro-turbine will
'cut-in' at under 350 RPM, whereas competitor
products are still free-wheeling until they reach 500 RPM.
- Low cost but
heavy-duty construction.
- Roof-mountable where appropriate (roof
mounting isn't always the best option)
- Ideal for PV augmentation.
The Wren Micro-turbine has two modes of operation.
1.
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.
2. Alternatively the Wren Micro-turbine will soon be available with
a battery-less Micro 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 of 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.
APPLICATIONS
OFF-GRID LIGHTING, WATER PUMPING,
ELECTRIC FENCES, YACHTS & BOATS, ROAD SIGNS , BATTERY CHARGING
POWER FOR DEVELOPING COUNTRIES. * CAN BE USED WITH SOLAR PV
PANELS FOR RELIABLE POWER PRODUCTION.
Charge Controllers - a diversion
charge controller is required to prevent the batteries being
overcharged and damaged. A diversion charge controllers operates by
switching on a dump load once the batteries reach high volatges. The
dump load then consumes the power from the turbine.

Wren Extreme
Wren Extreme is a Wren Micro-turbine variant with key component
changes to make the unit perfect for use in marine and industrial
applications. Key component upgrades include a new yaw pivot and
bearing arrangement to allow the turbine to cope with the large
forces involved with a pitching a rolling vessel on the open
ocean. Other upgrades include ingress protected slip-rings and
anodised bearing housings for protection against saltwater
corrosion. A new stator configuration with advanced cooling
further allows the turbine to run through 'big winds' without
worry of burn-outs or failure.

Wren Guyed Tower Kit
The Wren Guyed Tower Kit is a cost effective, user friendly
mounting solution for your Wren Micro-turbine. The tower kit can
be installed in as little as 1 hour by a single person and is
capable of providing tower heights of up to 7.5 metres. The kit
components are manufactured from heavy duty steel which is then
powder coated for corrosion protection. Helical earth anchors
allow easy fixing of the guy wire rigging which is all provided in
the kit. A length of scaffolding pole of 48.3mm steel circular
hollow section is needed to provide the main tower section. The
Wren Guyed Tower kit can be erected or lowered in seconds giving
easy access to the turbine.

Wren Building Mount Kit
This mounting solution can be used to mount the
Wren Micro-turbine to an existing structure or building. The mount
kit is manufactured from heavy-duty steel, industrial vibration
isolation materials, all of which are zinc plated and powder
coated for excellent resistance to weathering. The mount kit is
designed for a number of fixing options, and can withstand high
wind loadings on the Wren Micro-turbine. A main tower length of up
to 3 metres can be used by employing standard 48.3mm diameter
circular hollow section (not supplied)
Unsuitable for use with friable mortar, sand lime
mortar, aerated concrete blocks.
