    摘要: Provided in the present application are a string-type inversion-boost all-in-one machine and a power station system. The string-type inversion-boost all-in-one machine comprises: a low-voltage switch, a boost device, and a plurality of string inversion units, wherein each string inversion unit, the low-voltage switch and the boost device are all arranged on a platform of the string-type inversion-boost all-in-one machine; an alternating-current side of each string inversion unit is electrically connected to the boost device by means of a low-voltage alternating-current bus and a low-voltage switch cabinet in sequence; and a direct-current wiring area of each string inversion unit is arranged on the outer side of the string-type inversion-boost all-in-one machine. Therefore, an inverter and the boost device are integrated together, and the onsite wiring of the string-type inversion-boost all-in-one machine is convenient and simple.
