Wind and Solar Hybrid Controller Color: 12v/20000w Overview A controller designed for wind and solar complementary street lighting and off grid household use. It optimizes available wind and solar resources to provide stable charging and intelligent load control. Robust construction and multiple operating modes make it suitable for remote lighting, small community projects, and home backup systems. Key benefits Efficient hybrid charging: Fan boost MPPT charging for wind turbines ensures continuous charging at low wind speeds; PWM charging for solar panels provides reliable photovoltaic input. Flexible power options: Works with battery or photovoltaic panel as the main power source and supports 12V, 24V, or 48V systems. Reliable protection: Built in protections for reverse solar charge, overcharge, undervoltage, overvoltage, battery reverse connection, and open circuit conditions. Durable construction: Machined from aviation grade aluminum with an anodized finish for impact resistance and long service life. Easy operation: LCD display and configurable modes make setup and daily operation straightforward. Functions and features Dual power supply function: battery plus solar energy support. Wind charging: boost MPPT technology for the fan charging circuit, enabling efficient charging at low wind speeds. Solar charging: PWM technology using series MOS tubes for stable panel charging. Stepless shedding function: adjustable load shedding including an external discharge resistor. Multiple working modes: pure light control mode, normally open mode, light control plus time control mode with four programmable periods plus morning light. DC load output: three selectable output modes; each mode can be configured independently. Heat dissipation: aluminum profile heat dissipation and self cooling. Display: LCD for clear status and easy configuration. Automatic parameter setup: select battery type and the controller will set parameters automatically, with manual adjustment available for specific needs. Protections: solar reverse charge protection, overcharge and undervoltage protection, overvoltage protection, battery reverse connection protection, open circuit protection, and PWM overcurrent control.
