Description

SL-02B series solar controller upgrade increases the functionality of voltage and current display, has more Compatibility with a variety of storage batteries such as lead-acid battery ,VRLA battery , gelled electrolyte (GEL)Battery, 3.2V*4 iron-phosphate-based lithium battery 3.2V*8 iron- phosphate-based lithium battery ,3.7V*3 lithium battery,3.7V*6 lithium battery, and 3.7V*4 lithium battery.

User can set the model of battery.For your further satisfaction, additional 4 groups of Voltage adjustment parameters are available in the controller, which allows user to conduct personalized adjustment of the parameters for the selected battery.

For example, we can set the battery parameters which help prolong the service life, also old battery’s parameters can be adjusted to the favorable for longer discharge time, parameters can be changed into favorable according to various environments.

The adjustment function is up to the strict discharging requirements of some battery manufacturer, these characters enable user to operate freely compared with the previous version without this function.

The controller has the parameters for adjusting the threshold voltage of solar panel, by using the parameters, users can control the time of lighting on in the evening or lighting off at dawn, or for street lamp engineering, it can decrease the time difference result from the asynchronous on or off for multi- optical control switches.


Product Features:

  • Newly Upgraded: voltage and current display,Using 4 digital LEDs display and settings,intuitive and easy to use.
  • Newly Upgraded: The voltage of solar panel can be shown and checked, light-operated the threshold voltage is set flexibility which can recognize day and night reliably according to the voltage of solar panel. 
  • Newly Upgraded: The charge-discharge parameters of wide range can be adjusted flexibly, which is suitable for various kinds of battery, such as lithium battery. The old and new battery can all be applied to.
  • Newly Upgraded: Floating charge voltage can also be set, which can be especially applied to charge and discharge at the same time, controlling the voltage of battery flexibly
  • Newly Upgraded: Automatic temperature compensation and adjustable compensating parameter, for example, the lithium battery can choose the closing temperature compensation.
  • Newly Upgraded: The USB5V voltage-stabilized source output, for other 5V load like mobile phone charging that compatible USB. 
  • Rely on solar panels to start the controller works, To serious under-voltage or zero voltage battery charging, So that the battery back to normal.
  • Various protections include over-charge, over-discharge and over-load, as well as unique electron short circuit protection and connection-reverse protection. All the protections are harmless to any parts and fuse. fuse only as the end protection of a controller itself to protect the amount of internal short circuit damage.
  • Parameter is set to power-down save function, the system model and control parameters, and other important data are stored inside the chip, after power is not lost, to make the adjustment more convenient, more reliable system.
  • Automatic identification of system voltage classes
  • Intelligent PWM charge mode
  • Configurable load operating mode
  • Back discharge protection of battery
  • Low-voltage protection of battery
  • Transposition protection of battery
  • Overload and short-circuit protection

  •  ** Precaution**:

    • Please read user manual after you receive the item. 
    • Double check polarity(+/-) after connect each cable to terminal. Use multimeter to double check polarity & voltage.
    • Do not reverse polarity & sort circuit. Damage caused by improper installation / Burning will void the warranty!
    • Make sure the solar panel output is within solar controller specification.
    • Make sure connect battery 1st before solar panel & load so that controller can determine solar system voltage. Battery should in normal voltage range.
    • Do not connect AC power Inverter to solar contoller load output, connect directly to Battery.
    • Although this controller has multiple protective measures, but this is not panacea!
