Chtoocy 25W Smart Solar Fan for Coop & Greenhouse – 3 Modes, 2500mAh Battery, IP65

Powerful off-grid ventilation with built-in battery

Designed for chicken coops, greenhouses, sheds, and other off-grid spaces, the Chtoocy 25W Smart Solar Fan combines airflow with energy independence. A built-in 2500mAh battery stores energy captured by the 25W solar panel, powering ongoing ventilation through daylight, night hours, and overcast periods. The result is a steadier breeze that helps prevent heat pockets and stale air, while quietly supporting your space’s routine upkeep.

Three smart modes with memory

Choose a speed that feels right for the moment, then let the system remember your preference. High and Low speeds address sudden heat spikes; a timer can cycle the fan on and off for efficient cooling; Auto-Sense activates when infrared detection notices activity, turning the fan on and off to save power. Your last settings persist after restarts, so you don’t have to babysit the controller.

• High and Low speed options for quick adjustment
• Timer modes with 1h on/1h off or 1h on/2h off
• Auto-Sense mode uses infrared detection to start airflow and conserve energy

DIY dual-fan ventilation for versatile setups

The system includes two 120 CFM solar-powered fans and 6 meters of total cable, enabling flexible placement. Use them together for strong cross-ventilation or separately as intake and exhaust to suit your space, from coops to garages.

• Two 120 CFM fans for robust airflow
• 6 meters of cable length for flexible mounting
• Compatible with intake, exhaust, or cross-vent configurations

Efficient solar power and longer operation

The upgraded 25W solar panel recharges the internal battery faster, helping maintain continuous airflow after sundown. Even in low-light conditions, the system is built to perform, providing predictable ventilation when you need it most.

All-weather durability and weatherproof design

Constructed from rugged ABS and metal, with an IP65 rating for water and dust resistance. This solar exhaust fan is built to endure outdoor environments in coops, sheds, greenhouses, and other non-climate-controlled spaces.

Installation tips and practical setup guidance

For best results, connect the controller to the solar panel first to start charging, then install the fans and wiring. Plan your fan size and position according to your space and airflow goals for optimal comfort and efficiency.
