How to use a solar exhaust fan

Four universal usage methods for solar exhaust fans, roof fans, and heat dissipation fans：



1. Fan+adapter, the adapter has a voltage reduction function and can be used for 110V~220V household electricity

2. The fan and solar panel can only be used normally when there is sunlight during the day, and cannot be used on cloudy days, rainy days, or at night. The working voltage of the solar panel should match the fan, and you can refer to the product details and specifications for selection

3. Wind turbine+lithium battery+solar panel, please note that the voltage of the lithium battery should be consistent with the working voltage of the wind turbine, and the voltage of the solar panel should match the voltage of the lithium battery. If you need to self match the lithium battery and solar panel, please contact us for communication.

4. Wind turbine+lead-acid battery+controller+solar panel. The wind turbine, lead-acid battery, and solar panel are all connected through the controller. The voltage of the lead-acid battery should be consistent with the working voltage of the wind turbine, and the voltage of the solar panel should match the voltage of the lead-acid battery. The controller can automatically adapt to the battery voltage. If you need to match the lead-acid battery and solar panel by yourself, please contact us for communication.

Attention:

This product is a 12V DC exhaust fan, not a 220V AC. Please be aware.
