Abstract
The invention relates to a method and an arrangement for the surge protection of inverters for photovoltaic systems, comprising at least one surge protection device which is physically integrated in the inverter or can be found in the vicinity of the inverter. The at least one surge protection device is connected to the DC side of the inverter. According to the invention, the inverter supplies a signal for setting or tracking the operating point at an operating level in the maximum power point (MPP) range, the response voltage of the surge protection device being predetermined, set, or selected on the basis of said signal.
