Product overview This wind and solar hybrid MPPT controller is designed for offgrid systems to automatically manage charging and discharging of batteries. It supports wind turbine boost charging and solar panel PWM charging, offers selectable operating modes, and provides clear parameter display for monitoring and adjustment. Typical applications include communication base stations, household offgrid systems, street lighting, and monitoring systems. Key benefits Maximizes energy capture from wind and solar sources using MPPT boost for the wind turbine and PWM control for solar, improving charging efficiency especially at low wind speeds. Improves system reliability by supporting dual power inputs (battery plus solar), enabling continued power generation from either source when available. Reduces load on the battery with intelligent discharge control and external discharge support, extending battery life and stabilizing system output. Simple onsite setup and monitoring via a clear LCD that shows voltage, battery state, currents, power, charge mode, temperature, and other adjustable parameters. Robust construction and protective conformal coating on the circuit board to resist dust, moisture, and static, for stable longterm operation.

PWM solar charging: low controller power consumption and stable solar charging using series MOSFET PWM. PWM stepless discharge: supports external discharge devices and intelligent solar separation charge. Dual power supply function: accepts battery plus solar input for flexible power management. Adjustable load output modes: choose the working mode that fits the load and lighting schedule. performance control chip for stable regulation and protection functions. Circuit board coated with three layers of protective coating to reduce dust, moisture, and staticrelated faults. Compact aluminum alloy housing for durability and heat dissipation. Practical use scenarios Communication base station backup: Manage battery charging from a wind turbine and solar panels, maintain stable power to critical equipment, and protect against overcurrent on the load. Rural household offgrid system: Combine small wind and solar arrays to extend daily energy availability, monitor battery state and adjust charge/discharge parameters through the LCD. Street lighting and monitoring systems: Use lightcontrol and programmable timecontrol modes to run lighting schedules, provide automatic discharge control for LED drivers, and ensure continuous operation during variable weather. Packing list 1 x Wind and Solar Hybrid Controller 1 x External Discharge Resistor Safety and installation notes Warning: Do not plug or unplug the power adapter with wet hands. When connecting, follow the specified connection methods and precautions for wind, solar, battery, and load terminals to avoid damage. Configure voltage and operating modes to match your battery system (12V, 24V, or 48V) before normal operation. This controller offers a practical solution for small offgrid systems that need automated, efficient charging and flexible load control from combined wind and solar sources.
