1/5/10Pcs Solar Generator Charge Controller Auto Light Switch Lithium Battery Charging Board DIY Courtyard Street Light

Product selling points:1. Use high-quality materials with guaranteed quality2. Automatic control switch for photovoltaic solar charging and discharging, suitable for various battery voltages3. Easy to use and portable4. Charge during the day, turn on the lights automatically at night, and turn off the lights automatically at dawn5. Low power controllers are suitable for solar courtyard lights, lawn lights, string lights, small street lights, etcFeatures:Charging during the day, automatically turning on the lights in the evening, and automatically turning off the lights at dawn. The battery outputs voltage when there is no voltage, and the circuit controls the output by detecting changes in the voltage generated by the solar panel, without the need for photosensitive components; Suitable for multiple types of batteries.Wiring method:1. B+B - connected to lithium battery2. S+S-connected to solar panel3. L+L - connected to outputWiring sequence:1: The lithium battery must be connected with a corresponding protective board2: When the LED lithium battery is charged, the LED lights up3: When the solar panel is connected, the LED with light shining on the solar panel will turn off and the LED without light shining will turn onIf it needs to be turned off at night or transported for storage, the reserved switch interface SW can be disconnected to install the switch📢Notes:1: The stable working output current of the control board cannot exceed 600mA, otherwise it may cause output protection2: Charging anti backflow without overcharge and over discharge protection: Lithium batteries must be equipped with corresponding protection boards (mobile phone batteries all come with 3.7V protection, 18650+batteries do not come with it) Cannot be used in series with a 3.7V protective board3: Pay attention to waterproofing and insulation4: LED lighting fixtures cannot use boost drive5: The controller battery voltage is the output voltage, with unlimited current and voltage limit. The 2V3VLED LED beads cannot be directly used and need to be driven by voltage reduction and constant current or series current limiting resistors. The output current is the maximum working current and not a constant currentSpecial Reminder:1: Please confirm the actual power consumption of the load before using the output power as the actual power2: Directly connecting 3Ved may damage the controller or LED3: The battery must be equipped with a protective plate, and the battery voltage should match the open circuit voltage of the solar panelPacking list:Solar control switch circuit board * 1
