FAQ：

ALow voltage protection and disposal？  

If the screen shows as the right figure, it means the battery voltage is lower than the protection voltage. The controller enters into the low voltage protection state and the load loop disconnects. Use the solar panels or charger to charge for the battery .When battery voltage recovers to the protection voltage, the controller will recover to supply power for load and enter into the working state.

 

 Overloading protection and disposal？

   If the screen shows as the right figure, and the light flickers, it mean the current of the load loop is 1.2 times of the rated current within 3 seconds, and the controller is at overload state. After removing some loads, the controller will supply power to the loads automatically within seconds, or you can press button to recover the power supply compulsively.  

 

    Short -circuit protection and disposal?

If the screen shows as the right figure, and the light flickers, it means there happens short-circuit in the load loop, and the controller is at short-circuit  protection state. Please check whether the loads are damaged and whether the connecting cables are short-circuit. After eliminating the break down, press the button to recover the power supply for the loads.

 

 Breakdown and disposal of solar panels？

Sign flickering means the controller do not detect the existence of solar panels. Please check whether  the connection with solar panels are in good condition, and check whether the cables connecting the solar panels and controller are in open-circuit condition.

 

Load impulsion breakdown？

 If the  flickers when you turn on the load, it means the starting impulsion current is more than twice of the rated working current. Please restart the controller for times.
