    I-V400w - I-V500w - SOLAR I-Vw - SOLAR I-Ve 11.2. NOTES ON MPPT (MAXIMUM POWER POINT TRACKER) Solar irradiation on a surface such as the surface of a photovoltaic system has extremely variable characteristics, since it depends on the position of the sun with respect to the surface and on atmospheric conditions (typically, on the presence of clouds).

    I-V400w - I-V500w - SOLAR I-Vw - SOLAR I-Ve The reason why MPPTs are used is simple: a photovoltaic system without MPPTs may operate anyway; however, with the same solar irradiation, it provides less energy. There are inverters with 1, 2 or also 3 inbuilt MPPTs available on the market. Typically, the inverters with more than one MPPT are used in systems where: the different photovoltaic systems it consists of “forcibly”...
