Working Mode

There are several common working mode of solar controller:
1. Button Mode (Manual switching load)
2. Light Controlled Mode (Load switch is controlled by solar panels 
photosensitive control and timing control)
3. Light control turn on delay off mode.
4. Circulation model (With Clock Fuction)
0-24 hours optical mode,switch,wireless remote control mode,etc load mode optional


All kinds of complete protection,stable and reliable(charging over voltage protection,charging flow protection,over-current protection,load load short circuit protection,under-voltageprotection)
