🎥 Customer Demo: Wind Turbine Braking Function in Action!

We recently demonstrated our wind turbine braking function to a customer — and the results speak for themselves. In the demo, the turbine went from brake release to restart, to a complete stop, and back to rotating again. The entire process was controlled with just one click on a phone or computer.

Even if you're away on a business trip or vacation, you never have to worry about extreme weather damaging your turbine. You can check its operating status anytime on your phone and brake instantly if needed — no distance limits.

⚙️ Key Features of Our Wind Tracker Controller:
⏱️ Instant Braking – One-click control via APP or PC
📊 Real-Time Monitoring – Generator speed & wind speed on screen
🛡️ Auto Brake & Speed Reduce – Over-speed & over-voltage protection
📈 Power Curve Control – Optimizes output based on speed vs power
🔧 Customizable – Supports various sensor control functions
🔌 Wide Compatibility – Works with Growatt, Deye, Solis, Invt, and more

Whether you're at home or abroad, our controller gives you peace of mind.

🙏 Thank you to our customer for the trust and support!
