Wellsee mppt controller WS-MPPT*0 *0A (also known as
WELLSEE solar controller,charge controller,solar charge
controller,solar regulator,solar mppt,mppt solar,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 *0%**0%. WELLSEE mppt
controller *0A***0A includes *2V series, *4V series and *8V
series.
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 *2V
,only outputs a power point of *3W (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 *5W (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 solar charge 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 *0%.
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 *0%**0%.
