solar controller, auto-identify 12V and 24V, 20A, three years' warranty

Product Name: solar controller (12V/24V auto-indentified, 20A)

Model: STK-20

Description:

Microchip's MCU is used for the solar controller. With its all action Controlled by software, the controller has a higher accuracy and higher stability.

This controller's can automatically identify voltages, which avoids system mismatching and makes it more convenient to modify the system if any changes in the future. Then, the lifetime of the whole system would be extended.

The solar controller is applied to solar street light, solar garden light, solar lawn lamp, solar lamp box, solar advertising board, solar traffic light and solar power box etc.

Features:

1. Automatically identify input voltage

2. Self-check

3. Reverse current protection

4. over charging protection

5. Restoration interval

6. Overloading protection

7. Battery reverse connection protection

8. Thunder protection and so on                       

9. LED indicator

10. PWM function to automatically adjust light

11. Two loads output: L1 and L2

12. Light control

13. Time control with timer.

Options of loads’ function:

1. Set loads to 24 hours' outputting.

2. Set loads to light control.

3. Set loads to light control plus time control. You can set whatever time you like. However, it should not be more than 12 hours. If so, light control will function first and the time control will be meaningless then.

4. Set loads to light control plus PWM function. When PWM works, the solar controller can adjust the output power to half in later night so as to save power. Sure, you can set how long the PWM will work.

5. Set loads to light control+time control (time adjustable) +time control (time adjustable).
6. Set loads to light control+time control (time adjustable) +PWM (time adjustable)+time control(time adjustable)

7. AC electricity compensation. This means the AC electricity will start to charge the battery automatically when the battery voltage goes lower than 11V and no sunlight to charge the battery at that time.

The special function of Sunergy’s solar controllers:

Sunergy’s research team have developed and upgraded most of the solar controllers to the remote control version. That means users can use a remote control that Sunergy provide to set the above 7 mentioned functions of any loads independently.
