This product is a multi-functional LCD display solar controller with clock display function and 7 operation modes. 7 operation modes adjustable function, charging mode, light control mode, light control + time delay control mode, general control mode, manual control mode, timing control mode and test mode, where the test mode is only for factory test use.

Features:
Large LCD display, support battery working status display, solar panel working status display, mode control display, load output status and each parameter display, normal and fault status display.
7 operation modes are charging mode, light control mode, light control + time delay control mode, general control mode, manual control mode, timing control mode and test mode, the test mode is only for factory test use.
Four kinds of voltages automatic identification, it will automatic identify DC12V/24V, DC36V, DC48V by itself.
Automatic focusing MPPT tracking charging, high charging efficiency, nonstop detection during charging, bidirectional focusing tracking.
Equipped with time setting function and parameter values setting function.
Charging control function is not limited to any mode restrictions, as long as the charging conditions are met, it will be charged immediately.
The discharge control function varies according to the different control modes, in the absence of faults, as described below:
Charging mode: No discharge under any condition.
Light control mode: When the controller detects night, the discharge is opened with a delay of 10 minutes; when daytime is detected, the discharge is stopped with a delay of 10 minutes.
Light control + time delay control mode: when the controller detects night, the time delay of 10 minutes to starts the discharge, and starts counting down - time, when the timer is 0, the discharge stops. The maximum delay time is 23:59.
General control mode: If no fault, it will keep the discharge state.
Manual control mode: Use "▼" to turn on the discharge or stop the discharge.
Timing control mode: turn on the discharge at regular intervals and turn off the discharge at regular intervals.
T est: the same as light control + time delay control mode, only with less 10 minutes delay time.
The controller in the low-voltage protection, if you still need to discharge, you can long press the "▼" button for 5 seconds, you can still output, but only manually stop the discharge, note that this function may harm the battery, please use caution.
