Safety advice Safety advice:
1. Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
2. The battery cable should be as short as possible to minimize loss
3. The controller is only suitable for lead batteries:open, AGM, is not acid suited for nickel metal hydride,lithium ions or other batteries
4. The charge for regulating controller is only solar modules.Never suitable connect another charging source to the charge controller
5.The controller will be heating during operation.Please be careful to install the controller in a smooth,well-ventilated surface

Feacture :

1. Build-in industrial micro controller 

2. Large screen LCD display,charge and discharge parameters can be adjusted ,with power off memory function.

3.Screen with backlight (Note:backlight ,backlight in no operation after 5S or so automatically shut down)

4.Dual USB output ,the maximum current of 2.5A ,to support Apple's mobile phone charging 

5 Fully 3-State PWM charge management

6.Build-in short-circuit protection,open-circuit protection ,reverse protection ,over-load protection 

7.Reverse current protection ,low hear production 


1.The battery positive and negative pole according to the icon access controller ,the controller will automatically detect the battery voltage ,the load positive and negative pole according to the icon access controller ,pay attention not to answer ,the solar panel according to the icon access controller ,

Note:1. please strictly follow the above order to access ,otherwise it may damage the controller or other components ;the disassembly sequence is contrary to the wiring order 

2. 12V system with 17.5V solar panels ,24V system with 36V solar panels 

3.Load system Light,only that the load output has been turned on ,and there is no connection to the laod ,

4.12V load output of the largest 24V .120W maximum outupt 240W .the laod can nto exceed the output power ,if there is an inverter ,the inverter can be directly connected to the battery ,because the inverter iteself comes with under voltage protection 

As long as it is not set to [1-13H] or [0H] model ,(The optical delay model).Battery not under pressure condition (Battery symbol does not blink),Single short press the turn key can open/close load output
