P49
Stall-Regulated, High-Wind Turbine.
The P49 is engineered for sites where wind speeds are strong and simplicity matters most.
Utilizing passive stall regulation and a dual-speed generator configuration, the P49 delivers reliable performance without the complexity of active pitch systems. Fewer moving components mean lower capital cost, reduced maintenance, and predictable long-term operations — making it an ideal choice for high-wind environments where structural robustness and cost discipline are paramount.
Certified as per IEC 61400 edition 3 the P49 represents a deliberate engineering trade-off: maximize energy capture where wind is abundant, while minimizing mechanical complexity and lifecycle cost.
