Convert output voltage and current more efficiently

For designers and users of solar inverter systems, MPPT has many advantages. The first is that MPPT can more efficiently convert the output voltage and current of the solar power generation system, making the system performance more stable and reliable. In contrast, the modulation technique of PWM may cause energy loss and system instability.

Different environments can play the best efficiency

MPPT can make the system play the best efficiency in different environments. Because MPPT can adjust the system output power according to different environmental factors such as different light intensity and solar panel temperatures, it can be more suitable for use under various environmental conditions. The difference between MPPT and PWM lies in the circuit topology and working principle. The reason why MPPT can improve the power generation efficiency of the solar inverter system is mainly that it can adjust the output power of the solar inverter system in real time according to the change of the output voltage and current of the solar panel, and keep the device at the maximum power point. In contrast, PWM changes the system by continuously changing the duty cycle or switching frequency of the converter and adjusting the current, voltage, or power waveform of the system.

Provide better display and reporting capabilities

MPPT can provide better display and reporting functions. Some designs of MPPT can include monitoring instruments, through which various parameters such as current, voltage, power, and temperature of the solar inverter power generation system can be monitored in real time, and these data can also be uploaded to the cloud for analysis and statistics. For solar inverters System management, maintenance, and optimization are very important. In short, compared with PWM, MPPT has the advantages of higher system efficiency, higher adaptability, and better display and reporting functions, so it is more widely used and promoted in the design and use of solar inverter systems.
