PWM YSN-10A 12V / 24V Solar Panel Cell PV Charge Controller
 
PWM Solar Charge Controller 10A 20A 30A Back Light LCD Display Solar Regulator 12V 24V Auto with 5V Dual USB Output for Lighting
This is our Newest PWM Solar Controller 10A 20A 30A , It is only suitable for 12V and 24V Lead Acid Batteries :OPEN,AGM,GEL
it has Big Back Light LCD Display ,Dual USB Output and Load Light Control , you can use max 23V Solar Panel to charge your 12V battery ,or max 46V solar panel to charge your 24v battery ,it can be used for your home PV system !

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 ,even more high-garde(Note:some models have no 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 4-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 
 
 CONNECTION:
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
