Maximum Power Point Tracking (MPPT) system is a working state of the electrical module that enables the electrical system that can output more electrical energy can effectively store the DC electricity emitted by solar panels in the solar modules. It can effectively solve the life and industrial power consumption of conventional grids that cannot be covered in and in tourist areas, and does not produce environmental pollution.
The MPPT charge controller can detect the power generation voltage of solar panels in real time and track the maximum voltage current value (VI), so that the system is charged to the battery with a maximum power output. It is used in the solar energy system and coordinates the work of solar panels, batteries, and loads. It is the brain of solar energy system.
The role of MPPT
Regarding the role of MPPT, it can be reflected in one sentence: the output power of solar module cells is related to the working voltage of the MPPT controller. Only under the most appropriate voltage, its output power will have the only maximum value.
Because solar batteries have the influence of external factors such as light and environment, their output power changes, and the light emitted by light strong. The inverter with MPPT maximum power tracking is to fully use solar batteries to run it to run it At the maximum power point. In other words, when the solar radiation is unchanged, the output power after MPPT will be higher than that without MPPT.
The working principle of MPPT
MPPT charge controller is generally completed by DC/DC change circuit. The solar module array is connected to the DC/DC circuit through the load. The pure sine wave driver signal is adjusted.
For a linear circuit, when the load resistance is equal to the internal resistance of the power supply, the power supply has a maximum power output. Although solar panel and DC/DC conversion circuits are strong and non -linear, in a very short period of time, it can be considered as a linear circuit. Therefore, as long as the equivalent resistance of the DC-DC conversion circuit makes it always equal to the internal resistance of solar panels, the maximum output of solar modules can be achieved, and the MPPT of solar modules can be achieved.
In general, the MPPT charge controller will track the maximum power point in solar panels in real time to exert the maximum effect of solar panels. The higher the voltage, more power can be output through the maximum power tracking, thereby improving the charging efficiency. In this sense, the MPPT solar energy charging and discharge controller will inevitably replace the traditional solar controller.
