Features: 1Voltage and Power: The solar controller module has an input voltage of 3.7V, an output voltage of 6V, a power of 20W and a maximum output current of 5A. 2Multifunction: Our solar controller module has light control, time control, automatic power lowering and morning light function. Can do daily light up. 3Default Program: The controller module lights up before dark, 80% brightness for 1 hour before, 60% brightness for 1 hour in the second stage, 40% brightness for 2 hours in the third stage, 25% brightness power for 3 hours in the fourth stage. 4Free Switch Control: The controller module can be freely switched off or on to control the light, and can be set by the light control to turn on the light at night and turn on the light time, and the light can be turned off and on again in the middle. 5Constant Power: The controller module can set the infrared probe, constant brightness power, sense someone automatically enhance the brightness power. 6Delayed Lighting: Controller module can delay the lighting, this program plus the probe (not included) can be done as an alarm system, you can set the flashing alarm indication program. Item Type: Solar Controller Module Material: PCB Input Voltage: 3.7V Output Voltage: 6V Power: 20W Function: Light control, time control, automatic power lowering, morning light function Maximum Output Current: 5A Work Description: Receive light from the solar panel to control the controller, in lower visibility by the battery pack to the controller power supply voltage required to boost the LED lights to light up the lighting, controller constant current work Solar Panel input voltage during the day for the lithium battery pack charging, LED off state, when the lithium battery pack full capacity (i.e. battery voltage full) automatically stop charging.
