1. Using high-quality materials, the quality is guaranteed
2. Photovoltaic solar charge and discharge automatic control switch, suitable for a variety of battery voltages
3. Simple and portable to use
4. Charge during the day, automatically turn on the light when it is dark, and automatically turn off the light when it is bright
5. The low-power controller is suitable for solar garden lights, lawn lights, colorful string lights, small street lights, etc.

Features:

Charging in the daytime, automatically turning on the lights at night, and automatically turning off the lights at dawn, the output voltage is the output voltage when the battery has no voltage. The circuit controls the output by detecting the change of the voltage generated by the solar panel, without the need for photosensitive elements; it is suitable for a variety of batteries.

Wiring method:

• 1.B+B- connected lithium battery
• 2. S+ S- connect to solar panel
• 3. L+L- output

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.

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 cannot be used directly, it needs to be driven by a step-down constant current or a series current limiting resistor, and the output current is the maximum working current, not constant current

Special Note:

1. The output power is the actual power, please confirm the actual power consumption of the load before use
2. Direct access to 3Vled may damage the controller or LED
3. The battery must be equipped with a protective plate, and the battery voltage must match the open circuit voltage of the solar panel

The output of the Solar Charger is intended to charge a single polymer lithium ion cell. The load should be connected in parallel with the battery. By default, the Solar charge comes set to a maximum charge current of 500mA with a maximum recommended input of 6V (minimum 4.4V). It’s recommended that batteries not be charged at greater than their capacity rating.

Features:
Solar panel input: 4.4-6V
Max charge current: 500Ma
Interface: 2-pin JST connectors(or PH2.0)
Short circuit protection
Continuous Charge Current Up to 500mA
Battery status indication ( Red : Charging , Blue: Charged )
Micro-USB Connector
