MPPT controller, is not new to some people, its full name is: "Maximum power Point tracking" Solar controller, can be said to be the traditional solar charge and discharge controller upgrade products.
In order to give you a deeper understanding of this product, let's introduce the principle of MPPT Solar Controller
Before we understand how it works, let's first look at the role of the MPPT Solar Controller: Mppt is all known as maximum Power point Tracking, which is the maximum function tracking, which is a kind of electrical system that adjusts the working state of the electrical module so that the photovoltaic panel can output more electrical energy can effectively store the DC power emitted by the solar panel in the battery,
Can effectively solve the conventional power grid can not cover the remote areas and tourism areas of life and industrial electricity, without creating environmental pollution.
MPPT Solar Controller principle: The first step is to detect the DC voltage and output current of the main circuit, and then calculate the output power of the solar array, and finally realize the tracking of the maximum power point.
The following figure is a schematic diagram of the actual application of perturbation and observation methods to achieve maximum power point tracking. As shown, the connected perturbation resistors R and MOSFET, when the output voltage is basically stable, then change the average current through the resistor by changing the duty gap of the MOSFET, thus generating a disturbance of the current. At the same time, it will affect the output current and voltage of the photovoltaic cell, by measuring the change at this time, in order to determine the direction of disturbance in the next cycle.
If the disturbance direction is correct, the output power of the solar energy plate increases, the next period continues to disturb in the same direction, on the contrary, in the opposite direction disturbance, so repeatedly, so that the solar photovoltaic panel output up to the maximum power point.
