Detailed Product Description

MPPT Solar Charge Controller 10A 12V

MPPT(Maximum Power Point Tracking) Solar Charge Controller

JUTA MPPT-10 Model

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 charge controller, this MPPT controller could increase 10%-30%

electrical power using efficiency from solar panel.

Function: This MPPT controller 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.

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:

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:

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%.
