Solar Fan Accessory
Backup Energy Design & Smart Switchover System to realize solar fan's 24h running
With a smart controller, when connected to optional Solar Battery or AC / DC Power Adapter, SIPL solar roof fan can automatically switchover to backup power ( storage battery or grid electricity ) to run nonstop in sunless periods efficiently. No need manual operation. Furthermore, when the sun arise again, backup power will exit automatically and won't be used to power the fan, so as to reserve storage battery power or save more electricity.
Solar Storage Battery
The solar battery collects & stores energy at day time to support solar fan work continuously after sunset.
AC/ DC Dual Power Adapter
Connected to a power adapter, the solar fan can get grid electricity involved as backup power, to keep running even in sunless periods.
