A photovoltaic (PV) reverse polarity protection diode connector utilizes the unidirectional conductivity of a diode, connecting a reverse polarity protection diode in series with the positive terminal of each string. Its main functions are: to prevent backflow of current caused by reverse polarity connection of the PV module, which could burn out the PV module; to prevent current backflow (circulating current) caused by voltage differences between branches of the PV module array; and to act as a disconnect point when a fault occurs in its string, effectively isolating it from the system, protecting the faulty string while facilitating maintenance.
