Sonsight Wind’s Small Turbine Progresses Towards Certification
Sonsight Wind (Loganville, GA) has applied for certification from the SWCC for its 3.5 kW wind turbine (the SS3) and will begin certification testing in January 2026 to ACP101-1 standards, marking a key milestone in its commercialization pathway.
The SS3 is built around the patented Sonsight generator design which utilizes a segmented stator to allow more power at the lower RPM’s required by the oversize rotor. The 4.4m diameter rotor allows for more energy generation at moderate wind speed sites. Additionally, the higher torques facilitated by the design allow generator induced stall for primary overspeed control.
Facilitated by its relatively low mass and thrust, the SS3 bolts directly to a Skystream tower on which it has been tested throughout its development. The picture shows the SS3 at the test site in Beech Mountain, NC. The high turbulence at the mountain ridge location does affect performance, but it also provides opportunity for the documented power performance to provide a baseline for typical real-world deployment.
“Certification is a critical gate for market access,” noted Sonsight Wind CEO Devon Rocky McIntosh. “For us, it has been a long road getting here and it’s gratifying to be progressing through this process. We’ve designed the SS3 with versatility, reliability, and ease of deployment in mind—especially for distributed applications where simplicity and resilience matter most.”
Sonsight anticipates completing certification and UL listing by June 2026 with pilot installations and early commercial rollouts to follow. The company is actively preparing for this next phase.
