Price range: 170.00৳  through 200.00৳ 

ā˜€ļø Solar-powered switch that auto-lights at dusk and turns off at dawn
šŸ”Œ No light sensor required — voltage change triggers LED activation
šŸ“¦ Connects to lithium battery (with protection), solar panel & LEDs
šŸ› ļø Output via L+/Lāˆ’ port with optional SW switch interface
āš ļø 600mA max output current — stay within safe limits to avoid trip
šŸ’§ Requires waterproofing & heat insulation for outdoor use
⚔ Fuse variants: 0.5A auto-recover, 2.1A partial burn, 3.2A permanent burn
ā— Not constant current — use resistors or step-down LED drivers
šŸ““ Avoid boost circuits — 3V LEDs require proper limiting
šŸ“¦ Includes: 1 Ɨ Solar Auto LED Controller Board

Description
Feature:
1.Use high quality materials with guaranteed quality
2.Stable performance
3.Elegant appearance
4.Charging during the day, automatically turn on the light at night, and automatically turn 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 produced by the solar panel without the need for photosensitive elements.
Wiring method:
1. Lithium battery connected to B+B
2.S+S – connected to solar panel
3.L+L output
Wiring order:
1: To connect the lithium battery, the battery must have a corresponding protective plate
2: Connect the LED, the lithium battery is on, and the LED is on
3: Connect to the solar panel. At this time, the solar panel emits light, the LED is off, and the LED does not emit light.
If it is necessary to turn off the switch at night or the switch interface SW is reserved for transportation and storage, the switch can be installed.
Points to consider:
1: The stable operation output current of the control board cannot exceed 600 mA, otherwise it may cause output protection.
2: Charging and backflow prevention No overcharge and overdischarge protection Lithium batteries must be used with corresponding protection plates (mobile phone batteries have 3.7v protection, and more than 18650 batteries do not have 3.7v protection plates cannot be used in series)
3: Pay attention to waterproofing and thermal insulation
4: LED lamp cannot be powered by boost voltage
5: The controller’s battery voltage is the output voltage without limiting the current and voltage limitations. 2V3V LED beads cannot be used directly and need to be driven by a step-down constant current or a series current limiting resistor. The output current is the maximum working current, not a constant current.
6: Output power is the actual power, please confirm the actual power consumption of the load before use
7: Directly accessing the 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.
Not:
The 0.5A version of the fuse will automatically provide protection at 0.6-0.7A and will automatically recover when the current decreases.
The 2.1A version of the fuse will automatically provide protection when the current is 2-3A, and will automatically recover after the current is reduced (a small part will be permanently burned)
The 3.2A version of the fuse will burn permanently at 4-5A
