Common Questions What is included with the Photonic Universe 400W 12V Wind Turbine? The package typically includes the wind turbine body, five nylon fibre blades, a nose cone, an external MPPT wind charge controller, and basic mounting hardware for attaching to a pole. A user manual is also supplied. What kind of pole is required for mounting? A sturdy mounting pole is required, typically with a diameter of 48mm to 60mm. The pole itself is not included with the turbine and must be sourced separately to suit your specific installation needs and local wind conditions. Can this turbine charge 24V batteries? No, this specific WTJ400-12 model is designed and rated for 12V DC systems only. Attempting to connect it to a 24V battery bank may result in improper charging or damage to the system. A dedicated 24V wind turbine model would be required for 24V battery systems. How does the included MPPT charge controller function? The MPPT (Maximum Power Point Tracking) charge controller optimises the power output from the wind turbine, converting the variable AC output into a stable DC current for efficient charging of your 12V battery bank. It also provides essential safety features like over-charge protection for the batteries. Installation Notes Ensure the mounting pole is securely installed and capable of withstanding local wind loads. Connect the turbine's output to the included MPPT charge controller according to the manual's instructions. Connect the charge controller to your 12V battery bank, observing correct polarity. All wiring should be of appropriate gauge for the current and length of run to minimise voltage drop. For safety and optimal performance, professional installation is recommended. Before You Buy Verify that your existing system or intended application is compatible with a 12V DC power source. Assess your local wind conditions to ensure the turbine will operate effectively in your chosen location. Plan for a suitable, sturdy mounting pole and a clear, unobstructed area for the turbine's rotation. Confirm you have a compatible 12V battery bank for energy storage. Review the product manual for detailed installation and safety guidelines. Please verify all specifications and system compatibility before purchase.
