Cybrasc 25W Solar Exhaust Fan for Chicken Coop — Dual-Fan Kit, Thermostat & 2500mAh Battery

Cybrasc 25W Solar Exhaust Fan is a solar-powered dual-fan ventilation system with a 25W panel and 2500mAh battery designed to keep coops, outbuildings, and small shelters cooler and drier day and night.

This compact kit combines a high-efficiency 25W solar panel, an intelligent controller with temperature sensing and three operating modes, plus two durable fans that can be configured for intake, exhaust, or cross-ventilation. Built for off-grid use, the system charges in about four hours of sunlight and supports 4–6 hours of battery-powered operation, ensuring reliable airflow after sunset or during cloudy periods.

How does this fan keep a chicken coop comfortable?

The Cybrasc system moves air continuously or on demand to reduce heat, humidity and ammonia buildup without grid power. Dual fans speed airflow through the space while the thermometer-driven controller starts or stops the fans based on your preset temperature, which helps protect birds from overheating and damp conditions.

• Dual-fan layout supports intake, exhaust, or cross-ventilation for faster air exchange.
• 25W solar panel delivers rapid charging even in low light.
• 2500mAh battery sustains 4–6 hours of operation after charging.
• Thermostat mode automatically engages fans when temperature reaches set point.

What control and power options are available?

The included controller offers three modes—Timer, Thermostat, and Continuous—so you can schedule operation by clock, by temperature, or run the fan nonstop. The system seamlessly switches between solar input and battery power, keeping ventilation consistent through clouds and after dark.

• Timer Mode: program start/stop times for routine ventilation cycles.
• Thermostat Mode: set high and low temperatures to trigger the fan automatically.
• Continuous Mode: fans run 24/7 when constant airflow is needed.
• Solar/battery auto-switching preserves battery life and maintains ventilation.

How do I install and position the fan and panel?

Installation is straightforward: mount the solar panel where it receives direct sun, secure the controller in a sheltered, rain‑proof spot, then attach the fans to the wall or enclosure. The dual fans can be mounted side-by-side or separated to suit your coop layout and airflow requirements.

• Solar panel includes a mounting bracket for roof or post attachment.
• Controller should be placed in a dry location for longer lifespan.
• Fans are ABS + metal for weather resistance and long-term use.
• Wire and mounting points allow flexible fan placement for optimal circulation.

What maintenance and setup tips ensure best performance?

Before first use, fully charge the controller from the solar panel until the indicator turns green, then connect the fans. Place the temperature sensor inside the coop for accurate readings, keep the solar panel clean, and check mounts and wiring seasonally for wear.

• Charge controller fully before initial connection to the fan.
• Install temperature sensor inside the occupied space, not outside.
• Wipe solar panel periodically to maximize output.
• Inspect mounts and wiring annually for safety and reliability.

Who this is for: the Cybrasc 25W Solar Exhaust Fan is aimed at small‑scale poultry keepers, backyard farmers, and owners of off-grid structures—greenhouses, sheds, dog houses, RVs and barns—who want reliable, low-cost ventilation without running electrical lines. It suits anyone needing configurable airflow with simple installation and automated temperature- or time-based control, especially where power access is limited or sustainability is a priority.
