Zusammenfassung:	The utility model discloses a system for reducing series-parallel mismatch loss of photovoltaic groups. The scheme comprises a partial power conversion unit, a detection unit and a control unit, and the detection unit transmits the acquired voltage data and current data of the photovoltaic string to the control unit, so that the control unit can conveniently realize MPPT control on part of the power conversion units. The positive electrodes of the input ends of the partial power conversion units are connected with the negative electrodes of the photovoltaic strings, the positive electrodes of the photovoltaic strings are connected with the positive electrodes of the output ends of the partial power conversion units, and the negative electrodes of the input ends of the partial power conversion units are connected with the negative electrodes of the output ends of the partial power conversion units. The output end positive electrodes of the partial power conversion units are connected with the input end positiv
