From a technical point of view, the MPPT solar controller is bound to replace the traditional solar controller. However, at present I do not recommend the use of MPPT controllers for all PV systems. Because in terms of R&D and production costs, MPPT controllers are slightly higher than traditional solar controllers.

In low-power photovoltaic systems, it is more cost-effective to increase the power of photovoltaic panels than to use MPPT controllers. Based on this consideration, the application advantages of MPPT controllers cannot be reflected. If the photovoltaic off-grid system with more than 100W solar panels, we suggest that the MPPT controller can be used to improve the charging efficiency of solar energy, especially if the space area of the RV is limited, the NPPT controller should be used, so that in the limited space, Get more energy. If it is a photovoltaic off-grid power generation system of several kilowatts or more, the general engineering project will specify the controller of MPPT technology, and the advantages of MPPT are reflected.
