1750CFM Solar Powered Gable Mount Attic Fan AC Power Backup

Description

【2 Ways Power Supply: Solar(Priority)+ Electric(Secondary)】A smart power controller is included to allow automatic switching of the powe supply between solar panel and AC/DC power adapter. Solar power works when solar energy is equal and greater than 14V; solar + electric work together when solar energy is greater than 0 but less than14V; electric power works when solar energy is 0V. This Solar Fan even works on rainy days
Quite and waterproof brushless DC motor, 14 inches nylon-fiber-aluminum blades (7 blades not 3 ), galvanization steel housing and mounting frame
【Adjustable Solar Panel】: Horizontally & Vertically (15/30/45 degree. So you can make sure the sun is directly opposite the solar panel. Besides, the panel could be Remote Mounted

2 Ways Power Supply: Solar(Priority)+ Electric(Secondary)
A smart power controller is included to allow automatic switching of the powe supply between solar panel and AC/DC power adapter.
Solar power works when solar energy is equal and greater than 14V;
solar + electric work together when solar energy is greater than 0 but less than14V;
electric power works when solar energy is 0V.
7 Fan Blades
1. On Amazon marketplace, most solar exhaust fans only have 3 blades. But, our GBGS solar exhaust fans have 7 blades. So, our noise is as low as 40db while working.
2. Mounting frame design: several solar exhaust fans can be assembled together.(Note: Please buy extra screws)
3. Front side metal mesh: can stop insects from coming in.
Adjustable Solar Panel
Horizontally & Vertically (15/30/45 degree. So you can make sure the sun is directly opposite the solar panel.
