Maximum Power Point Tracking Technology

Due to the nonlinear characteristics of solar array, there is a maximum energy output point(Max Power Point) on its curve. Traditional controllers,with switch charging technology and PWM charging technology, can’t charge the battery at the maximum power point, so can’t harvest the maximum energy available from PV array, but the solar charge controller with Maximum Power Point Tracking(MPPT) Technology can lock on the point to harvest the maximum energy and deliver it the the battery.

The MPPT algorithm of our company continuously compares and adjusts the operating points to attempt to locate the maximum power point of the array. The tracking process is fully automatic and does not user adjustment.

As Figure 1-2, the curve is also the characteristic curve of the array, the MPPT technology will boost the battery charge current through tracking the MPPT.

Assuming 100% conversion efficiency of the solar system, in that way, the following formula is established:

Normally, the V(mpp) is always higher than V(bat), Due to the principle of conservation of energy, the I(bat) is always higher than I(PV). The greater the discrepancy between V(mpp)&V(bat), the greater the discrepancy between I(pv)&I(bat), The greater the discrepancy between array and battery, the bigger reduction of the conversion efficiency of the system, thus the controller’s conversion efficiency is particularly important in the PV system.

Figure 1-2 is the maximum power point curve, the shaded area is charging range of traditional solar charge controller(PWM Charging Mode), it can obviously diagnose that the MPPT mode can improve the usage of the solar energy resource. According to our test, the MPPT controller can raise 20%-30% efficiency compare to the PWM controller.(Value may be fluctuate due to the influence of the ambient circumstance and energy loss)

In actual application, as shading from cloud, tree and snow, the panel maybe appear Multi-MPPT, but in actually there is only one real Maximum Power Point. As the below Figure 1-3 shows:

If the program works improperly after appearing Multi-MPPT, the system will not work on the real max power point, which may wast most solar energy resources and seriously affect the normal operation of the system. The typical MPPT algorithm, designed by our company, can track the real MPP quickly and accurately, improve the utilization rate of the array and avoid the waste of resources.

PV Array Requirements

Serial connection (string) of PV modules

As the core component of PV system, controller could be suitable for various types of PV modules and maximize converting solar energy into electrical energy.

According to the open circuit voltage(Voc) and the maximum power point voltage (Vmpp) of the MPPT controller, the series number of different types PV modules can be calculated. The below table is for reference only.

NOTE: the above parameter values are calculated under standard test conditions(STC(Standard Test Condition) Irradiance 1000W/m2, Module Temperature 25C, Air Mass 1.5)
