The working principle of MPPT is: by real-time monitoring of the voltage and current of the photovoltaic panel as well as external environmental conditions (such as temperature and light intensity), a specific algorithm is used to control the output voltage of the photovoltaic module to be in a fixed range, and make slight changes within this range. Vibration to track the maximum power point to maximize energy harvesting efficiency. Specifically, because the output power is equal to the product of current and voltage, when the voltage changes, the current will also change according to the lighting conditions, so MPPT continuously adjusts the operating voltage and current of the photovoltaic panel to make it work at the maximum power point. In addition, the MPPT controller can also track the maximum output power of photovoltaic panels in real time, automatically adjust the operating point, and ensure the stable operation of the photovoltaic system, thereby maximizing energy utilization efficiency.
Compared with traditional solar controllers, MPPT controllers have the following advantages:
Improve energy efficiency: The maximum output power of photovoltaic panels can be tracked in real time to ensure that photovoltaic panels are always in optimal working condition.
Increase system stability: Using advanced electronic adjustment technology, it has high stability and reliability, and can automatically adapt to different light and temperature changes.
Provides a variety of protection functions: such as overvoltage protection, overcurrent protection, short circuit protection, etc., which can effectively protect photovoltaic panels and batteries from damage and extend the service life of the system.
