Double digital LED display, numbers equal to timer setting
Temperature compensation (with external temperature sensor)
Indicator LED:
1. Charger LED is used to indicate the charging status of battery, LED turn off means charging stopped.
2. Battery Status indicator: RED ON when battery under voltage, please charging, GREEN ON when the battery full.
3. There is output and load can work if the Load LED is lighting. There isn’t output and the load can work is the Load LED off.
Notice:
1. Please carefully check and confirm the voltage before wiring the components of the solar panel voltage is 18V, battery 12V, 12V rated voltage of the load.
2. The rated current of solar panels and load must be less than the rated current of controller.
