2000W 48V MPPT Wind Charge Controller With Dump Load

£799.00VAT Included

This charge controller is designed to charge a 48V battery bank using energy generated from wind turbines. It can accept input of up to 2000W of wind power (MPPT).

The controller uses MPPT boost 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 and voltage-boosting features, achieving the maximum available power from the wind turbine even in low-wind conditions. It also comes with a turbine braking function and external dump load to protect the battery and the turbine during high winds.



Key Features

  • Low Wind Boost Charging: During periods of low wind speed the voltage output of your turbine may be below the charging threshold of your battery. This innovative boost type controller can raise the voltage of the turbine to ensure it can keep charging a 48V battery from wind turbine voltage as low as 8V.
  • 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/discharging 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 charger 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 48V wind turbines with 3-phase AC output.

Not recommended with batteries that have BMS integrations that can shut off the output (unless another source is present), this device needs power supply from the batteries at all times for dump load control.
