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.
②In 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
