Because the controller will protect battery undervoltage condition, prevent battery has long been depth discharge to cause damage. At this time we only need solar lamp automatic charging will increase the voltage of battery.

3, according to the controller light determine solar lights in normal discharge, and the battery voltage is normal, then consider whether the LED lamps and lanterns is not bright.
