One method used for this purpose is limiting the export power: The inverter dynamically adjusts the PV power production in order to ensure that export power to the grid does not exceed a preconfigured limit.

Accordingly, a unified current limiting scheme is developed, which calculates the limited active and reactive power levels by considering the interplay between the unbalanced currents, the
