摘要： In an overvoltage protection apparatus before an inverter configured to feed electric energy from a DC voltage source into an AC power grid, the overvoltage protection apparatus includes a DC voltage input stage. The DC voltage input stage includes at least two current-carrying lines and an EMC filter including interference suppressing capacitors and interference suppressing inductors, and surge arrestors configured to divert overvoltages with respect to ground are connected to the current-carrying lines after the EMC filter, from a point of view of the DC voltage source.
