Features:The battery voltage and the solar panel voltage and power must match theLED voltage and the power connected output must match the battery voltage.Features: Charge in the day, turn on the light automatically in the cold, turn off the light automatically at dawn. , and the battery voltage output voltage Output control circuit by detecting changes in solar panel voltage, eliminating the need for lighting elements and suitable for batteries.Scope of application: solar lawn lights, landscape, garden, walkway, DIY street, etc.Note: batteries are required to protect plates.Input voltage (Solar): 4.5 V-28 V DCVoltage:(Lithium Battery): 3.6 V-16.8 V (1 S-4 S);When the voltage is 22-28 V (<= 20 w ,<= 2A), access to lithium batteries: 4 SWhen the voltage is 18-22 V (<= 18 w ,<= 2A), access to lithium batteries: 3 Swhen the voltage is 10-14 V (<= 15 w ,<= 2A), access to lithium batteries. Yom: 2 Swhen the voltage is 5-7 V (<= 12 w ,<= 2A), access to lithium batteries: 1 S(LiFePO4 battery): 3.2 V-12.8 V (1 S-4 S)when strong. Voltage 18-22 V (<= 20 w ,<= 2A),4 Swhen voltage 12-14 V (<= 18 w ,<= 2A),3 Swhen voltage 9-12 V (< = 15 w ,<= 2A), 2 Swhen the input voltage is 4.5-7 V (<= 12 w ,<= 2A), 1 SLED power requirements:4 S is not more than 12 w3 S is not more than 9 w2S does not exceed 5w
1S does not exceed 3wNote:1. Board stable operation, output current: <= 600mA.2.Anti-reverse charging protection, over-charge protection and over-discharge protection. The battery must be protected.3.Control needs to pay attention to waterproof and insulation4.LED lamp can't use boost drive.5.Battery voltage regulator, the output voltage is not limited to the current, the voltage is limited. .6. LED lamp beads cannot be used directly and need to be driven by step-down drives or set current limiting resistors.7. LED lamp beads can not be used step up driver.8. If you need to turn off the night or transport, keep the switch interface SW reserved, and open it can be installed by cuttingthe wiring sequence:1. Battery (must have protection circuit)2. LED, (Lithium battery power and switch has been turned on the LED light at this time)3. Solar panel (At this time, the solar panel has LED and no LED light)
