3.2V-3.7V-12V General-purpose solar panel power generation controller charging circuit switch circuit board module

Product introduction:
1. Use high -quality materials, quality is guaranteed
2. Photovoltaic solar charging and discharge automatic control switch, suitable for multiple battery voltage
3. Simple and portable use
4. Charging during the day, automatically turn on the lights, turn off the light automatically
5. Small power controller is suitable for solar courtyard lights, lawn lights, color string lights, small street lights, etc.

Functional characteristics:
During the day, the light is automatically turned off and automatically turned off the light. The battery has no voltage and output voltage. The circuit is controlled by detecting the changes in the power generation voltage of solar panels to control the output without requiring light -sensitive components; it is suitable for multiple batteries.

Wiring method:
1.B+B-Lithium connection lithium tales
2.S+ S-Piece of solar panels
3. L+L-connected output

Wiring order:
1: Entering a lithium battery battery must bring the corresponding protective board
2: Enter the LED lithium battery with electricity at this time LED lights up
3: Reminded the solar board at this time the solar board has light irradiation LED and the lightless irradiation LED lights up
If you need to turn off at night or transport the storage of the switch interface SW, you can install the switch

Note:
1: The stable working output current of the control board cannot be greater than 600mA. Otherwise, it may cause output protection
2: Charging and anti -renewal without charging the protective lithium battery must be used with the corresponding protective board (mobile phone batteries have 3.7V protection, more than 18650 do not bring. Can not use 3.7V protective boards in series)
3: Pay attention to waterproof and insulation
4: LED lamps cannot be used for boost driver
5: The battery voltage of the controller is the output voltage, the unlimited flow limit voltage, the 2V3VLED lamp bead cannot be used directly, the use of voltage constant current drivers or serial restaurant is used, and the output current is the maximum working current of the non -constant current flow.

Special reminder:
1: The output power is to determine the actual power consumption of the load before the actual power is used
2: Directly accessing 3VLED may damage the controller or LED
3: The battery must bring a protective board battery voltage with the solar board opening voltage matching
