PWM Solar Charge Controller for Wind Turbine Hybrid Systems — Wind & Solar MPPT Integration

• Dual solar + wind input in one controller — eliminates need for separate controllers, reducing system complexity and cost
• Automatic wind turbine braking — protects turbine from overspeed damage during storms or battery-full conditions
• Built-in dump load controller — safely dissipates excess wind energy as heat when batteries are fully charged
• 3-phase AC wind input compatible — works with most small permanent magnet wind turbines (100W-600W)
• Auto system voltage detection — plug-and-play with 12V or 24V battery banks
• Comprehensive wind-specific protection — reverse current blocking, lightning protection, and overspeed monitoring
• Cost-effective hybrid solution — ideal for locations with complementary wind and solar resources

• Remote Off-Grid Cabins — Year-round power combining winter wind and summer solar resources
• Marine & Sailing — Wind generator plus solar panels for continuous onboard battery charging
• Telecom Towers — Hybrid renewable power for remote communication sites with diverse weather patterns
• Weather Stations — Reliable power in locations where solar alone may be insufficient in winter
• Agricultural Monitoring — Remote sensors and equipment in windy plains and coastal farmlands
• Mountain & Hilltop Installations — High-wind locations where solar-only systems underperform in winter

Q: What wind turbines are compatible?

A: Most 3-phase AC permanent magnet wind turbines rated 100W-600W. The controller accepts the raw 3-phase AC output and converts/regulates it for battery charging.

Q: Do I need a separate dump load resistor?

A: Yes, an external dump load resistor (rated for your turbine's power) is required. The controller's PWM driver manages power dissipation through this resistor when batteries are full.

Q: Can I use this with just solar or just wind?

A: Yes, the controller works with solar only, wind only, or both simultaneously. Unused inputs simply remain idle.

Q: How does the brake function work?

A: The controller shorts the wind turbine's 3-phase output through a braking resistor, slowing or stopping the turbine. Manual brake via switch or automatic activation on overspeed/high battery voltage.
