Zusammenfassung:	The utility model discloses a system for solving a photovoltaic power station PID effect. The system comprises photovoltaic cell assemblies, a DC convergence box, a DC power distribution cabinet and a grid-connected inverter. The photovoltaic cell assemblies are connected so that an assembly string is formed. Output of the positive and negative electrodes of the assembly string is respectively connected with input of the positive and negative electrodes of the DC convergence box. Output of the positive and negative electrodes of the DC convergence box is respectively connected with input of the positive and negative electrodes of the DC power distribution cabinet. Output of the positive and negative electrodes of the DC power distribution cabinet is connected with the grid-connected inverter. Input of the negative electrode of the DC convergence box is directly grounded, and input of the negative electrode of the DC power distribution cabinet is directly grounded.
