Iskra AT5 service and spares
The Iskra AT5 was a pioneering 5kW wind turbine renowned for its robust performance and reliability

The Britwind R9000 was a robust and highly efficient 5kW wind turbine, designed to maximise energy generation in a variety of settings, including residential, agricultural, and commercial locations. Renowned for its reliability and performance, the R9000 consistently delivered significant energy savings and sustainable benefits. It has now been superseded by the H5, but is still supported by us.
Key Features:
High Energy Output: Engineered for excellent performance even at moderate wind speeds, the R9000 could start generating electricity at wind speeds as low as 2.5 m/s (5.6 mph), with no cut-out wind speed, ensuring consistent operation even during high wind conditions.
Patented Technology: Featured the innovative Reactive Pitchâ„¢ system, automatically adjusting blade angles to optimise energy capture and maintain safety by controlling blade speed during high winds.
Durable Construction: Built with robust materials, including glass fibre reinforced composite blades, equipped with UV and anti-erosion coatings, the R9000 was designed for longevity, requiring minimal maintenance across its 20-year lifespan.
Low Maintenance Design: Incorporated a direct-drive system without a gearbox and an automatic ElectroBrakeâ„¢ mechanism with no moving parts, significantly reducing maintenance needs and enhancing overall reliability.
Quiet Operation: Its advanced blade design and gearbox-free direct drive system ensured minimal noise, making it ideal for installation in residential and sensitive commercial environments.
Performance:
The R9000 could reliably produce between 9,000 and 21,000 kWh annually, depending on the local wind resource, making it a substantial contributor to meeting diverse energy demands.
Applications:
The Britwind R9000 was particularly suitable for:
Residential Properties: Providing homeowners with an effective means to reduce electricity bills and enhance sustainability.
Agricultural Sites: Helping farms become energy-independent, reduce operational costs, and reliably power essential farming equipment.
Commercial Premises: Allowing businesses to meet sustainability targets, improve energy independence, and significantly lower overall energy expenses.
Investing in the Britwind R9000 offered long-term financial savings, greater energy security, and meaningful contributions toward a sustainable environment.
