This utility model discloses a three-phase string photovoltaic grid-connected device, belonging to the field of photovoltaic grid-connected inverters. The three-phase string photovoltaic grid-connected device of this utility model includes a housing, with a heat sink at the rear end of the housing. The heat sink has second mounting slots at both its upper and lower ends, and first fans are installed on both sides of the two second mounting slots.
