The development of new energy industry in our country is rapid, the number of DC-DC converter manufacturers is increasing, and the output is rising, but there is still a gap between the core competitiveness of enterprises and foreign enterprises, and there is still a lot of room for improvement in product performance.

MPPT controller, fully known as Maximum Power Point Tracking Solar Controller, is applied in photovoltaic power generation system. It can detect the power generation voltage of the solar panel in real time, track the highest voltage and current value, and charge the battery with maximum power, so that the solar panel can output more electric energy and store it effectively in the battery, to improve the power generation of the photovoltaic system. MPPT controller is the core component of the photovoltaic inverter in the photovoltaic power generation system, and it is an upgraded product of the traditional solar charging and discharging controller.

Photovoltaic power generation utilizes solar energy, and the intensity of sunlight is constantly changing, which limits the actual utilization rate. To maximize the power output of the photovoltaic inverter and meet the demand for maximum output electricity, the direct current voltage needs to operate at the maximum power point. Since the intensity of sunlight is constantly changing, the maximum power point is also changing, so it is necessary to track it in real time. The MPPT controller can track the maximum power point of the solar panel in real time, play its maximum role, and directly improve the power generation of the photovoltaic system, so it has become the development direction of the solar controller.

According to the "Deep Market Research and Investment Strategy Recommendation Report on MPPT Controller Industry 2022-2026" released by the New思界Industry Research Center, in 2021, the global MPPT controller market size was about 1.07 billion yuan, and it is expected that from 2021 to 2026, the global MPPT controller market will continue to grow at an average compound growth rate of about 5.5%, and the market size will reach about 1.4 billion yuan by 2026. In many countries around the world, photovoltaic power generation is an important alternative to traditional thermal power generation, and many countries have issued policies to promote its installed capacity, which is still in a rapid development process. In order to improve the power generation of photovoltaic systems, the market prospects for MPPT controller are broad.

In photovoltaic systems, MPPT control is generally realized through DC-DC converters, which are voltage converters that transform the input voltage to effectively output a fixed voltage. The MPPT controller continuously tracks the maximum power point, and when it changes, the DC voltage is changed using a DC-DC converter. China's new energy industry is developing rapidly, with the number of DC-DC converter manufacturers increasing and production rising, but there is still a gap in the core competitiveness of enterprises compared to foreign enterprises, and there is still room for improvement in product performance.

In overseas markets, the main manufacturers of MPPT controllers are German Phocos AG, German Steca, Dutch Victron Energy, Swiss Studer Innotec, American Morningstar, American Blue Sky Energy, American Renogy, American OutBack Power, etc.; in our country's market, the main manufacturers of MPPT controllers are Hui Neng Jing Dian, Shuo Ri New Energy, Yuan Fang Power, Shenzhen Rui Ran, etc.

Industry analysts in the New思界 say that MPPT controllers are the upgrading direction of traditional solar controllers, which are applied in photovoltaic power generation systems. They can track the maximum power point of solar panels in real time to regulate the direct current voltage, so that the photovoltaic inverter output power reaches the maximum, and improve the power generation of photovoltaic systems. Against the backdrop of the continuous and rapid development of the global photovoltaic industry and the continuous upgrading of photovoltaic power generation equipment technology, the application ratio of more advanced components in photovoltaic systems is increasing, and the penetration rate of MPPT controllers is increasing, with broad future development prospects.
