Intelligent Solar Charge Controller User’s Manual
Please read this instruction carefully before using it.

Installation Explanation：
Get ready the related tools & cables. We s est you choose the appropriate cables to ensure the current density ﹤4A/mm2 and this is good for reducing cable voltage drop. Recommendation：30A using 10mm2 cable。50A using 16 mm2 cable.
①  Check whether installation place accords with the relative safety rules. Please avoid installing and using the controller under the following conditions: wet, dusty places or places with flammable and 
explosive gases. 
② Install the controller at the vertical plane. Please     
refer to chapter 5 for more detailed info about the  
spacing between the installing holes. In order to  
make the controller have good thermal dissipation, 
please spare 10cm above & below the controller.
③ As shown as the right figure, connect the loads, battery and solar panels with the controller in order. Pay attention to connect the loads, battery and solar panels right.
③ Plug the external thermal sensor into the interface of the thermal-sensor on the left
of the controller.

  ⑤ If you need to use the remote monitoring function, please plug one side of the attached communication cable into the communication port which is on the right of the controller, and connect the other side with computer.

Disassemble: To avoid the accident, please dismantle the solar panels, battery, loads from the controller in order.
Attention: Connecting the battery reversed will not damage the controller, but will cause safety risk on your loads.
