Maximum Power Point Tracking(MPPT）
Especially in case of a clouded sky, when light intensity is changing continuously, an
ultra fast MPPT controller will improve energy harvest by up to
compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers
Advanced Maximum Power Point Detection
in case of partial shading conditions
If partial shading occurs, two or more maximum power points may be present on
the power-voltage curve. Conventional MPPT's tend to lock toalocal MPP, which may
not be the optimum MPP. The innovative fangpusun algorithm will always maximize
energy harvest by locking to the optimum MPP
Outstanding conversion efficiency
No cooling fan maximum efficiency exceeds 98%
Flexible charge algorithm
Fully programmable charge algorithm(see the software page on our website), and eight
preprogrammed algorithms, selectable with a rotagy switch(see manual for details)
Extensive electronic protection
■Over-temperature protection and power derating when temperature is high.
■PV short circuit and PV reverse polarity protection.
■PV reverse current protection.
Internal temperature sensor
Compensates absorption and float charge voltage for temperature
Graphical LCD display Simple menu-driven operation
Programming by buttons
■Compliant with European Standards(CE)
■Made in China
Maximum Power Point Tracking
Output current o of a solar panel as function of output voltage（V）
The maximum power point(MPP)is the point
Pmax along the curve where the product x V reaches its peak
Output power P=l as function of output voltage.
When using a PWM(not MPPT) controller the output voltage of the solar panel will be
nearly equal to the voltage of the battery, and will belower than Vmp.

1a) If more PV power is connected,the controller will limit input power to the stated maximum.
1b) PV voltage must exceed Vbat +5V for the controller to start. Thereafter minimum PV voltage is Vbat +1V.
