Small Wind Turbine EWTH 500W-A

Features:
- Excellent energy production in low wind conditions; typically 60% more energy at wind velocities of 5m/s
- Aluminum alloy blades and shell design in decent appearance and light weight feature
- Lower RPM rotational speed avoid the risk of over speed malfunction and bring lower noise emission
- Simple to install, easy to use and minimal maintenance
- Finned housing for efficient heat dissipation
- Dual ra e protection systems as reliable passive self‐furling and electromagnetic brake
