ADVANTAGES OF MPPT TECHNOLOGY VS PWM
EXPLANATION OF THE MPPT'S FUNCTIONING METHOD
Unlike a standard PWM regulator which lowers the panel's voltage to the battery's voltage, a MPPT regulator
(converter/regulator) uses all the panel's voltage and reconverts the excess of voltage into charging
intensity (cf. patterns below)
Voltage = 18,7 V
Intensity = 5,43
Power generated
100W
* MPPT efficiency 98%
ADVANTAGES OF THE UNITECK MPPT
UNIMPPT researches in real time (refreshes every 100 ms, one of the fastest MPPT solar charge controller
among on the market), the optimum power point of the panel, thus verifying if the voltage /intensity relation
has changed as to modify its conversion parameters in input and thus optimizing the output power.
