MPPT - Trailer solar controller

Release Time: 2022-03-22
It is common to install solar panels for saloon cars to generate electricity. The whole solar power system of saloon cars is composed of photovoltaic modules, solar controller, battery and load.
Working principle of MPPT (Maximum power point tracking)
The output characteristic of photovoltaic array is nonlinear, and its output is affected by sunshine intensity, ambient temperature and load.
Under certain sunshine intensity and ambient temperature, the photovoltaic array can work at different output voltages, but only at a certain output voltage value, the output power of the photovoltaic array can reach the maximum, then the operating point of the photovoltaic array reaches the highest point of the output power voltage curve, which is called the maximum power point.
Therefore, in photovoltaic power generation system, an important way to improve the overall efficiency of the system is to adjust the operating point of photovoltaic array in real time, so that it always works near the maximum power point, this process is called maximum power point tracking.
Sojourn rv inch of land, solar panel laid area is limited. In addition, the rv solar panels are basically tiled installation, itself will have a large degree of power loss.
Therefore, the plan to install solar panels, in order to let the rv solar system to give full play to the maximum efficiency and value, the choice of a good solar controller is the key factor.
