Product: 4000W hybrid wind and solar charge controller Available voltage configurations: 24V and 48V Compatible battery systems: 12V, 24V, 48V (lead acid and lithium) Overview A smart, stable controller designed for mixed wind and solar systems. Automatic parameter setup after selecting battery type, plus user settings, give reliable charging and clear control. The unit combines boost MPPT for wind charging and PWM solar charging through MOSFETs to optimize energy capture and protect battery life. Key benefits Stable, intelligent charging: Automatic batterytype recognition sets ideal charging parameters, while manual adjustments are available to match specific system needs. Charging voltage control remains steady under changing conditions. Efficient wind charging at low speeds: Boost MPPT technology for the wind input maintains efficient charge even when wind is weak, increasing usable energy from small turbines. Flexible solar input: Solar panels are managed with PWM control through series MOSFETs, providing safe, steady solar charging and simple integration with the wind input. Controlled discharge and dump load support: Stepless discharge control and support for an external unloading resistor protect the turbine and battery during production or fault conditions. Full system visibility: Large LCD displays wind, solar, load, voltage, current and other key parameters for easy monitoring and adjustment. Robust protection suite: Builtin protections include solar reverseconnection protection, overcharge and undervoltage protection, overload protection, battery reverseconnection and opencircuit protection, and lightning protection to reduce risk and improve conversion efficiency. Performance and compatibility Power rating: 4000W, suitable for mediumcapacity offgrid and hybrid systems. Voltage compatibility: Works with 12V, 24V and 48V battery systems; offered in 24V and 48V configurations. Battery types: Configurable for lead acid and lithium chemistries, with presets and user settings to match battery specifications. Control and display: Large LCD gives clear numeric and status readouts for wind and solar inputs, battery voltage, charging current, and load output for straightforward diagnostics and tuning. Practical applications Small offgrid home or cabin: Combine a small wind turbine and roof photovoltaic array to keep batteries charged reliably through variable weather and preserve battery life. Remote telecom or monitoring station: Maintain continuous power to communications and sensors where grid access is not available and equipment uptime is critical. Agricultural or rural installations: Power pumps, lighting, and control systems using hybrid wind and solar generation with automatic control and protective functions.
