Automatic Solar Panel 3.7V 7.4V 11.1V 30W Max Night Light LED Control Switch Garden Street Module

Product selling point:

: Use quality materials, quality is guaranteed.

: Delicate and compact appearance

: The circuit controls the output by detecting the voltage generated by the solar panel, without lighting elements.

: Charge during the day, automatically turn on the light when dark, automatically turn off the light when bright

: Scope of application: Solar Power, Street Lamps, Lawn Lamps, Landscape Lamps, Garden Lamps, Pathway Lamps, Lamp Strings, etc.

wire:

: Connect the lithium battery.

The battery must have the corresponding voltage protection.

: Access LED

AT this Time, LED lights (if not on, you can short T+T-Test)

: Connected to the SOLAR PANEL. At this time, the solar panel is illuminated with light, LED on and off without light brightness.

Caution:

: Stable work, the output current of the control board can not be greater than 3A, otherwise it may cause output protection.

: charging and anti-backflow, no overcharge and overdischarge protection, lithium batteries must be used with the corresponding protection board.

(The cell phone is 3.7V, and the 18650 battery is not 3.7V. plate and cannot use series)

: Pay attention to waterproof and insulation.

: LED lamps cannot use Boost DRIVE.

: Battery voltage, controller output voltage, no voltage limit and no voltage limit.

: 3.2V LED lamp beads outside can not use the battery directly, it needs to be driven by a step-down or set current limiting resistor.

(Example: 1WLED lamp bead needs is 3v260ma Using a 3.7V lithium battery, must step-down or string greater than 5 ohms current limiting resistor)

Notice! LEDs cannot be powered by Boost.

If the power does not work when the solar panel is not connected to facilitate transportation or storage, you can remove the resistor. R5 or manual switch
