Wiring sequence:
1: Connect the lithium battery, the battery must have the corresponding protection board
2: Connect to the LED, the lithium battery has power and the LED lights up
3: Connect to the solar panel. At this time, the solar panel is illuminated with light, and the LED is off, and the LED is on without light.
The switch can be installed if it needs to be turned off at night or the switch interface SW has been reserved for transportation and storage.
Charge voltage:
Lithium battery: 3.6V-16.8V (1-4 String )
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 (1-4 String )
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
Precautions:
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-backflow without overcharge and overdischarge protection Lithium batteries must be used with corresponding protection boards (mobile phone batteries all have 3.7v protection, and more than 18650 do not have them. 3.7v protection boards cannot be used in series)
3: Pay attention to waterproofing and insulation
4: LED lamps cannot use boost drive
5: The battery voltage of the controller is the output voltage, unlimited current and voltage limiting, 2V3V LED lamp beads
Package Include:
4 *Automatic Solar Panel Battery Charger Board
