1. Using the Epoxy resin sealed technology, increased the function like: fall-proof, earthquake-proof, waterproof, corrosion-proof, moisture-proof, and so on. Waterproof grade: IP68.

2．System voltage : 12V/24V automatic switch

3．Comprehensive reverse connection protection

4．Intelligently overload, short circuit and over voltage protection. (After over current protection, it will restart for every 2 mins, until releasing the failure)

5．Multi-working model choosing, multi-parameter adjusting, make the products more intelligently, more useful. 

6．It has temperature sensor outside, can make the temperature compensation more precise.

7．More advanced charging and discharging control algorithm, effectively increase the use of solar panels’ rate and battery life.

8．Design of high power density, all-aluminum case. Smaller sizes and better performance

9．Controller with infrared wireless receiving and sending function, matching the remote control can be achieved on the wireless programming to the controller.

10．SL remote control can only be used to change the controller model, set the light time at night and control the loads’ switch, these the simple functionality

If we use IRF remote control with LCD screen to complete more function setting for the controller

Controller recognizes dawn and dark by checking the open circuit voltage of solar panels.

12V system default is 2.5V as identified point (24V is 5V as identify point). Continue more than 15s and higher than 2.5V that is considered to be the daylight, continue more than 15s lower than 2.5V that is considered to be night time.   

Security:

1．  SL1024 the solar panel maximum input voltage is 55V, battery is 35V, please do not excess than this value. In 24V system, if battery voltage is higher than 31V, then the load will be closed. In 12V system, battery voltage higher than 15.5V, load will be closed.

2．  In 24V system, if solar panel or battery polarity connect reversed,  it might damage controller

3．  If battery connects correct, but load connects reversed, controllers will not be damaged, but loads may be damaged.

4．  Please be careful if you operate two or more than two errors at the same time, controller may be damaged.

Technical parameter:  (Pls consult with manufacture if you need the remote control)
