SYDNEY 48V 1 kW vertical wind turbine (spiral) + external regulator

Designed for turbulent and changing winds (city, built-up areas), the SYDNEY vertical wind turbine captures wind from all directions thanks to its spiral blades, and starts at 1.5 m/s.

Key features

• Spiral vertical axis: better tolerance to disturbed winds and direction changes
• 48V system: ideal for battery charging (reduced losses over longer connections)
• Permanent magnet generator + electromagnetic brake: operational stability and safety
• Starts at 1.5 m/s (charging starts at 3 m/s)
• External regulator included (optional): voltage/speed control to secure the installation

The SYDNEY 48V 1 kW is a spiral-type vertical axis wind turbine. Its curved blade optimizes capture and allows production even when the wind is irregular (corridor effect between buildings, gusts, direction changes). It is therefore particularly suitable for urban and peri-urban environments where winds are often disturbed.

Note: like any wind turbine, production becomes truly significant when the wind is consistently present on site (location/height/clearance play a huge role).

Compatibility & installation advice

• For installation on 48V batteries: you need a 48V wind turbine + wind controller, then the energy can be used via an inverter/hybrid like for solar.
• Beyond approximately 20 m between the wind turbine and equipment, 48V is generally preferred to limit voltage drop (cable sizing to be calculated).
• Mounting: the Wind Counter does not recommend gable/roof installation (turbulence/vibrations). Prefer an independent mast.
• Safety: grounding earth, shutdown/isolation and protections (circuit breaker, surge protector depending on site) — installation by a qualified person recommended.
• The Wind Counter sells equipment and advice: no installation/commissioning.
