Store Categories Store Categories Other 3.7V 7.4V 11.1V Lithium Photovoltaic Solar Controller Switch Circuit Board Details 1. Using high-quality materials, the quality is guaranteed 2. Delicate and compact appearance 3. The circuit controls the output by detecting the voltage generated by the solar panel, without photosensitive elements 4. Charge during the day, automatically turn on the light when it is dark, and automatically turn off the light when it is bright 5. Scope of application: solar energy, street lamps, lawn lamps, landscape lamps, garden lamps, corridor lamps, lantern strings, etc. Wiring: 1: Connect the lithium battery The battery must have a corresponding voltage protection board 2: Access LED At this time, the LED is on (if it is not on, you can short T+T- to test) 3: Connect to the solar panel. At this time, the solar panel is illuminated with light, and the LED is turned off without light illumination. Precautions: 1: The stable working output current of the control board cannot be greater than 3A, otherwise it may cause output protection 2: Charging and anti-backflow without overcharge and overdischarge protection Lithium batteries must be used with corresponding protection boards (Mobile phone batteries all have 3.7v protection, and 18650 batteries do not have 3.7v protection plates and cannot be used in series) 3: Pay attention to waterproofing and insulation 4: LED lamps cannot use boost drive 5: The battery voltage of the controller is the output voltage, unlimited current and voltage limiting. 3.2v LED lamp beads outside the battery cannot be used directly. It needs to be driven by a step-down constant current or a series current limiting resistor. (Example: 1wLED lamp beads work requirements are 3v260ma, using 3.7v lithium battery, need to step-down drive or string more than 5 ohms power resistor to limit current) Notice! LEDs cannot be driven by boost If the light does not light when the solar panel is not connected to facilitate transportation or storage, you can remove the resistor r5 or manual switch Package list: Board *1 Shipping Policy Payment Method Returns Policy Shipping Policy Payment Method This is the description of Payment Method.
