Photonic Universe is proud to offer this truly advanced wind charge controller, which uses a highly efficient wind power conversion technology. This product is the result of many years of research and development by an expert team of specialised wind power engineers.

This is a buck controller designed for 120V wind turbines. The high voltage input from the turbine is efficiently converted to charge a 48V battery system at maximum current. It can accept input of up to 3000W of wind power (MPPT).

The controller uses MPPT charging technology to unlock the full potential of your wind power system, ensuring optimal performance. The wind charging circuit is equipped with cutting-edge power tracking features, achieving the maximum available power from the wind turbine. It also comes with a turbine braking function and external dump load to protect the wind turbine and the battery during high winds.

Key Features

  • High Efficiency MPPT Charging: Using advanced Maximum Power Point Tracking (MPPT) technology, the controller optimises wind turbine performance by tracking the ideal power voltage point, maximising power output. It also allows the user to enter their own tracking points of the wind power curve if required.
  • Comprehensive Safety: The controller offers multiple protection functions, including safeguards against reverse current backflow, overvoltage, and high wind speeds. It also features automatic braking to prevent overcharging and turbine damage.
  • User-Friendly Interface: The controller's digital LCD display provides essential information like battery voltage, charging current, connection status of the wind turbine and battery charging status. It also alerts you to any system faults or abnormal values, such as low battery voltage.
  • Advanced Software Configuration: The charge controller can be configured using dedicated free software (Windows only), which connects through an RS232 port. The software allows the user to set many parameters such as charging and disconnect voltages, wind turbine overcurrent, wind turbine start voltage, wind braking settings, as well as to access monitoring and historical data.
  • External dump load: As an additional safety precaution, this controller also comes with an external dump load for further system protection. The controller will automatically detect when the battery bank is full and divert any excess energy directly to the dump load unit, connected to the dump load terminals of the controller. This prevents damage to system components including the batteries and wind turbine, which is particularly useful for applications with strong wind speeds where the battery is often rapidly charged.
  • Manual Brake Switch: The controller comes with a manual brake switch, allowing the user to manually apply the braking function for intense conditions and maintenance purposes.



This charge controller is compatible with our 3000W 120V wind turbine (WTD3000-120).
