Proven Wind Turbines

These powerful wind turbines, developed in Scotland, are built to withstand severe weather conditions and are a good size for stand alone domestic use, either for battery charging;

for heating; or grid connection.  

Their downwind design incorporates a unique three bladed self-regulating rotor coupled to a three phase permanent magnet alternator. This give high output in strong winds combined with good performance in low winds. Under high wind loading the turbine blades simply turn and flex with the wind - limiting output, whilst allowing continuing operation even during the fiercest storms.

Turbine and controller are protected in the event of accidental load disconnection.
The low rotor speed ensures extended durability of blades & bearings together with quiet operation. No gearbox.

Heavily built machines ensure long life. All components are hot-dipped galvanised steel, stainless steel or plastic. All bearings are triple sealed.

The 2.5kW & 6kW machines include a rotor safety disc brake operated from the tower base to allow the wind turbine to be stopped for maintenance.

Three types of system are possible for different applications using different voltage versions of the wind turbines.

 

Battery Charging Systems	For properties off the grid or where an independent power supply is required.
Heating  Systems	Where power is required for heating in windy weather.
Grid-Connect Systems	Allowing wind power to be used on normal properties to reduce electricity consumption.

Proven Specifications

Proven Brochure

Proven 0.6

• Rating: 600W in a 12m/s (26mph) wind

• Rotor Diameter: 2.3m

• Cut in Windspeed: 2.5m/s (5.6mph)

12, 24 or 48 V - battery charging   

These battery charging machines,  developed from the successful 2.5kW version and using the same blade technology are ideal for remote power supplies such as homes or telecommunications etc.  The controller prevents battery overcharging and diverts surplus power into a 600W space heater (included). Meters are available separately.  The ECM-601 version of the controller includes meters, an IP65 enclosure, adjustable low voltage relay and system status indicators.

For 150 V - grid connect

Used with Windy Boy WB-700 inverter.  Rectifier includes meters showing voltage and current.

Proven 2.5

• Rating: 2.5kW in a 12m/s (26mph) wind

• Voltage: 24, 48 or 120 Volts DC

• Rotor Diameter: 3.5m

• Cut in Windspeed: 2.5m/s (5.6mph)

2.5kW 6.5m mast Data Sheet

2.5kW 6.5m mast Foundation Pack

2.5kW 11m mast Data Sheet

2.5kW 11m mast Foundation Pack

The 24 & 48V machines use a battery for storage and can incorporate an inverter to supply 230Vac power.  The controller monitors battery voltage and diverts surplus power into heaters.

The 120V machine is used for heating only and the controller here matches the load (storage or immersion heaters etc.) to the wind conditions.

The standard 6.5m tower is a tubular tapered self-supporting  structure (needing no guy wires) with hinged base plate for easy erection onto a reinforced concrete base. An 11m tower is also available.

Proven 6

This wind turbine is ideal for power supplies to homes, farms or small businesses etc.

• Rating: 6.0kW in a 12m/s (26mph) wind

• Rotor Diameter: 5.6m

• Cut in Windspeed: 2.5m/s (5.6mph)

6kW Data Sheet

6kW 9m mast Foundation Pack

6kW 15m mast Foundation Pack

48V - battery charging

The 48V machine uses a storage batterr and can incorporate and inverter to supply 230 Vac power. The controller monitors battery voltage and diverts surplus power into heaters.  

120V or 240V - direct heating

These machines are used for direct heating only and the controller matches the load (storage or immersion heaters) to the wind conditions.

300V - grid connect

These are used with two Windy Boy inverters in connection with a normal mains supply.

Controller includes isolation switchgear and is suitable for either internal or external mounting.  Version with volt & ammeters for performance monitoring also available.

Accessories

Diversion Heating Loads

For use with battery charge controllers or in direct heating applications.

DC & AC elements to suit different controllers.

Immersion elements have standard fitting.

Winches

Tirfor winches are available for use when raising or lowering towers or hired when required.

T508 is needed for Proven 0.6 on 5.5m tower or Proven 2.5 on 6.5m tower;

T516 for Proven 2.5 on 11m;

T532 for Proven 6 on 9m & T532/30 for Proven 6 on 15m tower.

Proven Towers

Different tower heights are available to suit different site conditions. The standard towers are tubular, tapered self-supporting structures made from heavy duty galvanised steel.  They need no guy wires and take up the minimum of ground area.  Includes hinged base plate and gin pole for easy erection.

Requires a reinforced base.

1m x 1m x 1m for 5.5 & 6.5m towers;

2.5m x 2.5m x 1m for 9 & 11m towers;

3m x 3m x 1m for 15m tower.

Machined tower top adaptors are available for use with custom towers (un-galvanised upon request).
