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.
Claims9
A system for the surge protection of an inverter for a photovoltaic system, the system comprising:
- at least one surge protection device which is physically integrated in the inverter or located in the vicinity thereof, wherein the at least one surge protection device is connected to a direct current side of the inverter,
- wherein the inverter supplies a signal for adjusting or tracking an operating point to an operation in the range of a maximum power point (MPP), wherein a response voltage of the surge protection device is specified, adjusted or selected on the basis of this signal.
Arrangement for the surge protection of an inverter for a photovoltaic system, comprising:
- a group of surge protection devices electrically arranged and interconnected to be physically integrated in the inverter or located in the vicinity thereof, wherein the surge protection devices are connected to the direct current side of the inverter, wherein:
- the group of surge protection devices are configured to allow an adaptation of a response voltage resulting from a switching state of the surge protection devices to an MPP voltage.
