Specificatii
Wellsee mppt controller MPPT30 20A (also known as
WELLSEE solar controller,charge controller,solar charge
controller,solar regulator,PV controller) can intelligently
regulate the working voltage of solar panels, letting
the solar panels always work at Maximum Power Point of
V-A curve. Compared with ordinary solar controller,
this MPPT controller can increase the efficiency of PV
modules by 10%-30%.
MPPT advantage:
Maximum Power Point Tracking (MPPT in short) system is a
system which allows PV panels to outputs more Power by adjusting
working condition of the electrical module. In Figure1 A
indicates that the ordinary
controller, which makes PV battery work on 12V ,only
outputs a power point of 53W (a general power point), B indicates
that MPPT controller makes PV
battery always work at the maximum power point, thus outputs the
power point of 75W (the maximum power point).

MPPT principle:
The maximum power point is mainly affected by the
ambient temperature and the intensity of sunshine. The intensity of
sunshine being constant, the maximum output power decreases with
the rise of the temperature. The temperature being constant, when
the sunshine intensifies, the open circuit voltage of PV battery
basically keeps unchanged. But the short circuit current increases
substantially, thus the maximum output power increases
substantially.
This WS-MPPT mppt
controller can intelligently regulate the working
voltage of solar panels, letting
the solar panels always work at
Maximum Power Point of V-A curve. Compared with
ordinary solar controller,
this MPPT controller can
increase the efficiency of PV modules by about 30%.
However, due to many different factors, such as the
difference in solar
panel making, the change the Sun illuminance,
change in temperature, the efficiency of
the controller etc., the
actually available increased rate is 10%-30%.
