  • Day & Night Time Nonstop Running Solar Centrifugal Exhaust Fan

    The solar fan auto-runs directly powered by solar panel in sunny hours, and keeps running by auto-switchover to battery in sunless time.


    12.8V*9.6Ah lithium battery, charged by 30W solar panel

    Smart controller

    Lithium battery is expensive so the fan will not waste any battery power when not necessary, which is decided by the smart controller inside the fan. This controller will keep sensing output of the fan's solar panel. When output is low to certain level, it will switch in the battery power. And when output rises to certain voltage, it will cut the battery power to avoid any unnecessary cost.
