Features:
1. Use high-quality materials with guaranteed quality
2. Stable performance
3. Exquisite appearance
4. Charging during the day, automatically turning on the light at night, and automatically turning off the light at dawn. The output voltage is the output voltage when the battery has no voltage
5. This circuit controls the output by detecting changes in the voltage generated by the solar panel, without the need for photosensitive elements
Wiring method:
1. Lithium battery connected to B+B
2. S+S - connected to the solar panel
3. L+L-output
Wiring sequence:
1: To connect a lithium battery, the battery must have a corresponding protective plate
2: Connect the LED, the lithium battery is powered on, and the LED lights up
3: Connect to the solar panel. At this time, the solar panel emits light, the LED goes out, and the LED does not emit light.
If it is necessary to turn off the switch at night, or if the switch interface SW has been reserved for transportation and storage, the switch can be installed.
Matters needing attention:
1:The stable working output current of the control board cannot be greater than 600 ma, otherwise it may cause output protection
2:Charging and backflow prevention No overcharging and over discharge protection Lithium batteries must be used together with corresponding protection plates (mobile phone batteries have 3.7v protection, and over 18650 batteries do not. 3.7v protection plates cannot be used in series)
3:Pay attention to waterproof and thermal insulation
4:LED lamp cannot be driven by boost voltage
5:The battery voltage of the controller is the output voltage, without limiting current and voltage limitations. 2V3V LED beads cannot be used directly, and need to be driven by a step-down constant current or series current limiting resistor. The output current is the maximum operating current, not a constant current
6:The output power is the actual power, please confirm the actual power consumption of the load before use
7:Directly accessing a 3Vled may damage the controller or LED
8:The battery must be equipped with a protective plate, and the battery voltage must match the open circuit voltage of the solar panel
Reminder:
The 1.0.5A version of the fuse will automatically protect at 0.6-0.7A, and automatically recover when the current decreases
The 2.1A version of the fuse will automatically protect when the current is 2-3A, and will automatically recover after the current decreases (a small portion will be permanently burned)
The 3.2A version of the fuse will permanently burn out at 4-5A
