Manual JUTA MPPT Solar Regulator 12V 24V

Posted by admin in News

Feature:

The most important feature of this controller is intelligent tracking input voltage from solar panel, which could let solar panel always working at Maximum Power Point of V-A curve. Compared with normal solar regulator, this MPPT controller could increase 10%-30% electrical power using efficiency from solar panel.
                
Function:

This MPPT solar regulator is not only have above mentioned special function, at the same time including
completely Protecting and Controlling functions:

Overcharge protection
Overdischarge 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.
 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 regulator: 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 tempe-rature, different efficiency of solar regulator 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 vol-tage is18V above. 24V solar system should use 2pcs above mentioned solar panels. 48V solar system should use 4 pcs above mentioned solar panels.

 Conductor:

The cable between solar panel with MPPT solar regulator should be better calculated
 by 1Ampere per 1mm².
 solar regulator: JUTA brand MPPT-10 Model solar charge controller Rated input Ampere is 20A(30A). We have 12V, 24V and 48V three kinds of MPPT solar regulator (other specifications could be designed as customer special request).

 Fit for power of solar panels:
 12V :20—400Wp(600Wp)  24V:40—800Wp(1200Wp) 48V:80-1600Wp (2400Wp)
 

 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 higherinput 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 phenomenon 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 recover to 12.6V or (25.2v), the Load will be automatically working,at this time the indicator is off.Charge Indicator, green, bright indicate the battery need to charge, flickering means float charging, off means ch-arge has stop.

RESET Button: The rated output current of this MPPT solar regulator is 20A(30A), if there is short circuit or overload happened, the MPPT solar regulator will close output. ( Load indicator off, Low voltage indicator off.)
If you need the MPPT solar regulator 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.
Attention:

Please check the rated voltage of the solar panel, battery, load are all the same with 12V or 24V or 48V.
Please pay attention to connection, do not connect the “+” “-” poles of solar panels and load wrong.( Wrong connection will be burn your MPPT solar regulator)
Battery must be connected earlier than solar panels and load. When take off the system, Solar Panels must be take down first, then cut off battery.
The rated current of solar panel and load must be less than MPPT solar regulator’s rated current.
