Universal 3.2 to 12V Solar Controller Charging Street Light Switch Module

Universal 3.2 to 12V Solar Controller Charging Street Light Switch Module

Features:

• Universal 3.2/3.7/4/11.1/12V Solar Controller Charging Street Light Switch Module

• Photovoltaic solar charging and discharging automatic control switch, suitable for a variety of battery voltage

• Simple and portable to use

• Charge during the day, turn on the light automatically when it is dark, turn off the light automatically when it is light

• A small power controller is suitable for solar garden lights, lawn lights, colourful string lights, small street lights, and so on

• Wiring method: B+ and B-connect lithium battery; S+ and S-connect solar panel; L+ and L-connect output

Package includes:

• 1 x Module

Notes:

• The stable working output current of the control board cannot be greater than 600mA, otherwise, it may cause output protection

• 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)

• Pay attention to waterproofing and insulation

• LED lamps cannot use boost drive

• The battery voltage of the controller is the output voltage, unlimited current and voltage limiting, 2V/3V 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
