1.5 Smart mode (Selectable)

Mode 1: According to the battery charge and discharge status ,Output Power(Current)
will automatically optimize automatically to extend the LED lamp working hours.
① When the battery capacity is low, the controller will follow the diagram of "1.1 Load
Current Output Curve", reduce power output current to extent the LED lamp working
hours.
② In winter, when weak sunlight makes the charging less, equipment will enter into
half-power mode automatically.

Mode 2: Rely on external infrared and sound sensors to control load power
This mode need to connect an external IR sensor or sound sensor to sense whether
someone pass.When nobody passes, Output Power will reduce to the lowest power
working to save energy.(this mode is reserved)

1.6 History Record
1, Record the working days
2, Record the over discharge times of recent 16 days
