Information

MPPT actually means maximum power point tracking, which can be said to be an upgrade of PWM. PWM is pulse modulation. The control method is to control the on-off of the switching device of the inverter circuit, so that the output terminal can obtain a series of pulses of equal amplitude, and these pulses are used to replace the sine wave or the required waveform. That is, multiple pulses are generated in the half cycle of the output waveform, so that the equivalent voltage of each pulse is a sine waveform, and the obtained output is smooth and has few low-order harmonics. By modulating the width of each pulse according to certain rules, the magnitude of the output voltage of the inverter circuit can be changed, and the output frequency can also be changed.

To put it more simply and bluntly, the conversion rate of MPPT to photovoltaic panels is relatively large, which is more than twice the conversion rate of general PWM. Therefore, the price of MPPT is naturally more expensive. We all know that to improve the conversion rate, there are only two ways, one is to increase the number of solar panels, and the other is to use our MPPT controller. We all know that solar panels are expensive. MPPT controllers improve the utilization rate of solar panels, so saving the number of solar panels also saves money, so it is naturally more expensive.
