MPPT(Maximum Power Point Tracking) Solar Charge Controller
User’s manual
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
Battery
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: U
A
=13.2V
Charge Current:: I
A
=9.8A
Charge Power: P
A
=13.2*9.8=129.36w

MPPT Solar Charge Controller:
Solar Panel works at
point B state, the solar panel working voltage much
higher than battery voltage.
Charge Voltage: U
B
=18.4V,
Charge Current:: I
B
=9.3A
Charge Power: P
