The photoelectric system includes a maximum energy point tracking device, which is used to generate a voltage reference point to generate a voltage according to the voltage reference and the operation method of the photoelectric system.

摘要

A photovoltaic system includes solar cells and an inverter configured to convert direct current generated by the solar cells to alternating current. The photovoltaic system includes a maximum power point (MPP) tracking module configured to perform MPP tracking for the photovoltaic system. The MPP tracking module is configured to detect shading of the solar cells and to modify its MPP tracking to prevent tracking of local MPPs. The MPP tracking module may be incorporated in the inverter.
