Battery voltage and solar panel voltage and power must match
The LED operating voltage and power connected to the output must match the battery voltage.
Features: charging during the day, turning on the lights automatically in the evening, turning off the lights automatically at dawn, and the battery voltage is the output voltage. The circuit controls the output by detecting changes in the voltage of the solar panel, eliminating the need for photosensitive elements, and is suitable for a variety of batteries.
Scope of application: solar lawn lights, landscape lights, garden lights, corridor lights, DIY street lights, etc.
Note: Batteries must be used with protective plates.
Input voltage (solar): 4.5V-28V DC
Charge voltage:
(Lithium battery): 3.6V-16.8V (1S-4S);
When input voltage 22-28V(<=20w,<=2A), access lithium battery: 4S
When input voltage 18-22V(<=18w,<=2A), access lithium battery: 3S
When input voltage 10-14V(<=15w,<=2A), access lithium battery: 2S
When input voltage 5-7V(<=12w,<=2A), access lithium battery: 1S
(LiFePO4 battery): 3.2V-12.8V (1S-4S)
When input voltage 18-22V(<=20w,<=2A), 4S
When input voltage 12-14V(<=18w,<=2A), 3S
When input voltage 9-12V(<=15w,<=2A), 2S
When input voltage 4.5-7V(<=12w,<=2A), 1S
LED lights requirements:
4S can not exceed 12w
3S can not exceed 9w
2S can not exceed 5w
1S can not exceed 3w
Note：
1. The board stable working output current: <= 600mA
2. Anti-reverse charging prevents over-charge and over-discharge protection. Batteries need to be protected.
3. The control board needs to pay attention to waterproof and insulation.
4. The LED lamp can't use boost drive.
5. The controller battery voltage is the output voltage, unlimited current limit voltage.
6. The LED lamp beads can not be used directly and need to be driven by a step-down drive or a series current limiting resistor.
7. The LED lamp beads can not be used step up driver.
8. If you need to close at night or transport storage The switch interface SW has been reserved, and the opening can be installed by cutting.
Wiring sequence:
1. Battery (must with protection circuit),
2. LED, (Lithium battery has power and the switch has been turned on, LED lights up at this time)
3. Solar panels (At this time, the solar panel has a light LED off and no light LED on).
