Chtoocy 25W Smart Solar Fan for Chicken Coop & Shed — 2026 model, dual 120 CFM fans, 2500mAh battery, IP65

The Chtoocy 25W Smart Solar Fan is a weatherproof, battery-backed solar ventilation system designed to deliver continuous airflow for chicken coops, dog sheds, greenhouses and other small outbuildings.

Whether you need reliable cooling on hot afternoons, odor control in a coop, or stale-air removal from a shed without running grid power, this upgraded 2026 model combines a 25W solar panel, built-in 2500mAh battery inside a smart controller, and two compact 120 CFM fans to keep air moving day and night. The unit is built for outdoor use (IP65) and offers three programmable operation modes plus a memory function that preserves your settings after power interruptions.

How does the solar fan keep airflow after the sun goes down?

The integrated smart controller stores energy in its 2500mAh battery, allowing the fans to operate during evening hours and overcast conditions. The larger 25W panel charges faster than smaller panels, so the system reaches useful stored capacity in about 4–6 hours of sunlight.

• Built-in 2500mAh battery inside the controller for nighttime runtime.
• 25W solar panel charges ~30% faster than lower-watt panels.
• Works in low-light conditions and conserves power with automatic modes.

What control settings and smart features are available?

The controller offers three main modes: fixed High or Low speed, Timer cycling, and Auto-Sense with infrared detection. It also remembers the last selected setting after a restart, so you don’t have to reconfigure the system after a storm or brief power loss.

• High and Low fan speeds for direct manual control.
• Timer options: 1 hour on/1 hour off or 1 hour on/2 hours off for regular cycling.
• Auto-Sense uses infrared detection to run only when needed, extending stored power.
• Memory function retains your last mode and speed after resets.

How flexible is installation and where can I use these fans?

The kit includes two 120 CFM fans and 6 meters of cable so you can configure intake, exhaust, or cross-ventilation as the layout requires. Fans are compact and lightweight for easy DIY mounting in coop walls, greenhouse vents, shed gables, or garage openings.

• Two fans for paired intake/exhaust or independent installations.
• 6 meters of cable included to reach panels and controllers as needed.
• Rugged ABS and metal housing with IP65 rating for outdoor exposure.
• Suitable for chicken coops, dog sheds, greenhouses, attics, garages.

What durability and weather protection does the unit provide?

The fan bodies and controller use corrosion-resistant materials and an IP65 rating to shed rain and dust. This outdoor-rated construction helps the system endure seasonal changes without frequent maintenance.

• IP65 waterproof rating for resistance to rain and dust.
• ABS and metal construction for impact and corrosion resistance.
• Solar panel designed for outdoor mounting with secure brackets.

Who is this for: The Chtoocy 25W Smart Solar Fan is aimed at homesteaders, small-farm owners, and anyone who needs off-grid ventilation for animal housing, greenhouses, storage sheds, dog runs, or garages. It’s a good fit if you want a low-maintenance, energy-free airflow solution with smart controls and overnight capability without wiring to the mains.

Warm tip: For first use, connect the controller to the solar panel to charge the built-in battery before final fan installation. Plan fan size and placement to match airflow needs and avoid blocking intake/exhaust openings.
