Lewisia 10W Solar Dual Fan Ventilation Kit — 4400mAh Battery, Timer & Temp Control (IPX5)

Lewisia's 10W Solar Dual Fan is a weatherproof, battery-backed ventilation kit with timer and temperature control designed to keep small outdoor structures cool and well-aired.

Whether you need steady airflow in a chicken coop, greenhouse, shed, pet house or small garage, this complete system pairs a 10W solar panel with two coordinated fans, an intelligent controller and a 4400mAh battery for continuous performance through daylight and short evenings. The compact IPX5-rated fans can be configured for intake, exhaust or a push-pull arrangement to tailor airflow to your layout. The built-in LCD controller displays temperature and run-time settings so you can automate ventilation based on heat or schedule.

How does the dual-fan layout improve air movement in cramped spaces?

The two fans can be installed as both exhausts, both intakes, or one intake and one exhaust to create a push-pull airflow pattern. This flexibility helps remove hot, moist air while drawing in cooler, fresher air, which reduces humidity and stagnation more effectively than a single fan.

• Push-pull configuration accelerates air exchange for faster cooling.
• Dual intake or dual exhaust options adapt to available mounting points.
• Balanced airflow reduces hotspots and moisture buildup.

What control options are available for scheduling and temperature response?

The integrated digital controller offers two working modes: timed operation and temperature-triggered ventilation. Use the timer to run fans during selected hours, or set a temperature threshold so the system activates automatically when heat rises.

• Clear LCD shows current temperature and remaining run-time.
• Timer mode for scheduled ventilation during peak heat periods.
• Temperature mode for automatic on/off based on measured heat.

How does the solar panel and battery combination keep the fans running at night?

The included 10W solar panel supplies power during daylight to run the fans and recharge the internal 4400mAh battery. When light levels drop or clouds block sunlight, the battery provides backup energy for up to approximately three hours on a full charge, ensuring continued ventilation into the evening.

• 10W panel for efficient daytime charging and operation.
• 4400mAh battery stores energy for nighttime or overcast periods.
• Automatic crossover from solar to battery keeps settings and operation seamless.

Is this system built to handle outdoor exposure and is it easy to install?

The fans are rated IPX5 for water resistance and the kit includes mounting brackets and hardware for straightforward installation on walls or vents. Components are ruggedly constructed to withstand rain and routine outdoor conditions, while the controller and clear LCD keep setup and adjustments simple.

• IPX5-rated fans resist rain and splash exposure.
• Mounting brackets included for quick wall or vent installation.
• Plug-and-play wiring and clear controller reduce installation time.

Who this product suits: Owners of small outdoor structures who want reliable, off-grid ventilation — especially hobby farmers, greenhouse growers, pet owners and anyone with a shed or garage lacking good airflow. If you need an energy-efficient way to lower heat and humidity, reduce odors, and maintain fresher air without constant mains power, the Lewisia 10W Solar Dual Fan kit offers configurable airflow, automated control and weather-resistant construction to meet those needs.
