WS-MPPT15 SOLAR PANEL CHARGE CONTROLLER
This WS-MPPT15 SOLAR PANEL CHARGE CONTROLLER( also known as WELLSEE
intelligent solar charge controller, solar charge controller, 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% .
WELLSEE WS-MPPT solar controllers 10A--60A include 12V series, 24V
series and 48V 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 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 solar 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% .

Bluelight and Wellsee New Energy Industry Co., Ltd
Solar photovoltaic industry has been known as the sunshine industry
because of its environment-friendly characteristics and broad
prospects.
WELLSEE New Energy Industry Co., LTD is the large-scale
professional independent research and development manufacturing
enterprises. WELLSEE company has won the trust of domestic and
abroad customers by its advanced technology, perfect design, top
quality and excellent service, and its photovoltaic products have
exported all over the world.
WELLSEE products domestic sales and exports sales alarmingly rise
every year. With years of rich experiences and keen market insight,
WELLSEE management decided to expand the scale of production which
covered the whole solar system, including five projects : solar
panels, solar controllers, solar inverters, solar lights, and solar
batteries.
Currently, WELLSEE company has appropriated a large land to build
PV production base --WELLSEE ( China) Photoelectric CO., LTD , the
base located in national high-tech development zone, Wuhan City,
covering 68 mu( 45, 333.33 square meters) , with the aim to build a
modern garden-PV Series Development and production base.
WELLSEE PV production base has Well-developed transportation
condition, adjacent to the international airport and railway. The
10, 000 ton-class deepwater wharfs is under construction just 2
kilometers away from the PV base, and the new Yangtze River Bridge
here has approved and under investigation now. Besides, Wuhan
largest logistics hub will be built up here soon. The land has
great investment value and unlimited appreciation potential!
The major construction projects of WELLSEE PV production base
include: Office buildings, staff dormitory , executives residential
building, staff canteen, research buildings, manufacturing
workshop. The Infrastructure construction expense is more than 50
million yuan, and production equipment and working capital are more
than 80 million yuan. After the company established, it can solve
the local employment problem, hire more than 500 people. Besides,
the company profits and taxes will exceed 100 million.
