JUTA MPPT 10A 12V Solar Panel Battery Charge Controller only for Solar PV system


Function: This MPPT controller is not only have above mentioned special function, at the same time including completely Protecting and Controlling functions:
Overcharge protection
Over-discharge protection
Battery Reverse Current Protection
Overloading Protection
Short Circuit Protection
Reverse Polarity Connection Protection

Schematic Diagram: Picture 2 shows typical 12V battery solar charge system V-A curve.
Normal Solar Charge Controller: Solar Panel works at point A state, the solar panel working voltage is a little higher than battery voltage.
Charge Voltage: UA=13.2V
Charge Current:: IA=9.8A
Charge Power: PA=13.2*9.8=129.36w
Area in drawing: ①+③ 
MPPT Solar Charge Controller: Solar Panel works at point B state, the solar panel working voltage much higher than battery voltage.
Charge Voltage: UB=18.4V, 
Charge Current::  IB=9.3A  
Charge Power: PB=18.4*9.3=171.12w  
Area in drawing: ①+②

Comparison: The power B is more than power A..
△P/ PA =(PB— PA)/ PA=32..3%
As a result of different manufacture of solar panels, different solar illumination intensity, different temperature, different efficiency of solar charge controller and so on. The effective power increase rate is 10-30%.

Form a complete set: 
Solar Panel: 12V solar system should use 40pcs cells laminated solar panel. The maximum power point voltage is18V above. 24V solar 
system should use 2pcs above mentioned solar panels. 48V solar system should use 4pcs above mentioned solar panels.
Conductor: The cable between solar panel with MPPT solar charge controller should be better calculated by 1Ampere per 1mm².
Solar Charge Controller: MPPT-10 Model solar charge controller Rated input Ampere is 10A. We have 12V, 24V and 48V three kinds of MPPT solar charge controllers (other specifications could be designed as customer special request). Fit for power of solar panels: 20—200Wp(12V), 40—400Wp(24V), 80-800Wp (48V).

Connection: ( As Picture 3 according to below process)

Connected the “+”, “-” poles of the battery to the controller ( 3, 4 from left) firmly and correctly. At this time the LOAD green LED is bright. If the LOAD green LED is not bright, it is indicate there is battery reverse polarity connection. Only LOAD green LED is bright, we could continue next step operation.
Connected the “+”, “-” poles of the solar panel to the controller (1,2 from the left) firmly and correctly.
Connected the “+”, “-” poles of the LOAD to the controller (5,6 from the left) firmly and correctly.
Simply Measure Methord: For 12V system, measure the input voltage from solar panel with multimeter (terminal 1, 2 of controller), it is normal if the voltage of solar panel more than battery voltage 0.5-6V. Generally, the higher input voltage, the better charge efficiency. For 24v and 48V system, the input 
voltage will be much more higher than battery voltage
(Note: It is normal the controller can not find Maximum Power Point within 10 minutes from system start.)
Indicator: (Picture 1)

Load indicator, green, bright indicate there is output, Load could work, “off” indicate there is not output, Load can not work.
Low Voltage Indicator, red, bright indicate the voltage of the battery is low. Load could not normal working. This is normal phenomenon. When the battery voltage recovers to 12.6V or (25.2v), the Load will be automatically working, at this time the indicator is off.
Charge Indicator, red, bright indicate the battery need to charge, flickering means float charging, off means charge has stop.
RESET Button: The rated output current of this MPPT solar charge controller is 10A, if there is short circuit or overload happened, the MPPT controller will close output. ( Load indicator off, Low voltage indicator off.)
If you need the MPPT controller recover work, please check the reasons and clear out the fault firstly. Then put a small stick such as toothpick, ball-pen tip inside the RESET hole, and press RESET button will be OK.
