Wind and Solar Hybrid Controller Color: 24V/20000W Overview This controller is designed for wind and solar complementary street lighting and small off grid systems. It optimizes power from both wind and solar sources, providing stable charging, flexible output control, and built in protection. The unit can also be configured for household use with simple settings. Key benefits Reliable dual power support: combines battery storage with solar input to keep lights and DC loads running when either source fluctuates. Efficient charging at low wind speeds: fan charging uses boost MPPT technology for continuous, efficient energy capture from wind turbines. Stable solar charging: PWM solar charging with series MOS tube design ensures controlled charging and improved conversion stability. Flexible control options: multiple working modes let you match operation to site needs, including light sensing, timing, and normally open operation. Robust build and thermal design: aviation grade aluminum housing with anodized finish for impact resistance plus aluminum profile cooling and self cooling for reliable heat dissipation. Easy operation: LCD display and automatic parameter setup after selecting battery type, with manual adjustment available. Functions and features Dual power supply: battery and solar panel supported. Fan charging: MPPT boost charging for wind turbines, capable of efficient charging at low RPM. Solar charging: PWM control using series MOS tubes. Load control modes: pure light control, normally open, light control plus time control (four time periods plus morning light); each DC output mode can be set independently. Stepless shedding and external shedding resistor supported for load management. Display: LCD for status, settings, and monitoring. Protections: solar reverse charging prevention, overcharge protection, undervoltage protection, overvoltage protection, battery reverse connection protection, open circuit protection, and overcurrent handling. Smart operation: automatic parameter configuration when battery type is selected; adjustable settings to suit specific batteries or loads. Construction: one time molded tensile aviation aluminum with anodized surface, designed to resist impact and drops. Heat dissipation: aluminum profile heat sink and natural self cooling. Operating range: 20 to +55 C, 35 to 85% RH, no condensation.
