Wind Turbine Assembly

  1. Mounting the Blades: Attach the three blades to the hub using the provided hardware. Ensure the copper rings are correctly positioned to protect the blade material.
  2. Attaching the Tail Fin: Secure the tail fin to the generator body.
  3. Mounting to Pole: Secure the wind turbine generator body to a sturdy mounting pole using the flange connection. Ensure the pole is firmly anchored and provides adequate clearance.

Electrical Connection to Controller

The wind turbine generator produces 3-phase AC power. Connect these three wires to the corresponding input terminals on the MPPT/PWM Wind Charge Controller.

This video demonstrates the connection process for the MPPT/PWM Wind Charge Controller. It shows how to connect the wind generator's output wires to the controller and then connect the controller to a battery. Pay close attention to polarity when connecting to the battery.

  1. Connect Wind Generator to Controller: Connect the three output wires from the wind generator to the three blue input terminals on the MPPT/PWM Wind Charge Controller (labeled with wind turbine symbols).
  2. Connect Battery to Controller: Connect the positive (+) and negative (-) terminals of your 12V battery to the corresponding red (+) and black (-) terminals on the charge controller (labeled "Bat"). Ensure correct polarity.
  3. Connect Loads: Connect your DC loads or inverter to the battery terminals, ensuring appropriate fusing and circuit protection. Refer to the system wiring diagram for a complete overview.

6. Operating Instructions

Initial Startup

Once all connections are secure, the wind turbine will begin generating power when wind speeds exceed the 2m/s start-up speed. The charge controller will manage the charging of your battery.

Normal Operation

The wind turbine operates automatically, adjusting its direction to face the wind. The charge controller continuously monitors battery voltage and wind generator output to optimize charging and prevent overcharging.

Shut Down Procedures

In situations requiring shutdown (e.g., extreme weather, maintenance), activate the braking mechanism on the charge controller if available, or manually secure the blades to prevent rotation. Disconnect the battery from the controller as a primary safety measure.

7. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your wind turbine.

  • Annual Inspection: Visually inspect all components for wear, corrosion, or damage. Check blades for cracks or chips.
  • Bolt Tightness: Periodically check and tighten all mounting bolts and electrical connections.
  • Cleaning: Keep blades and the generator body clean from dirt, ice, or debris that could affect performance.
  • Electrical Connections: Inspect wiring for fraying or loose connections.

8. Troubleshooting
