Abstract

The present invention relates to means for adapting a power rotation angle of an electrical inverter to match the unknown grid impedance at the point of connection. The invention further relates to an electrical inverter comprising such means. The present invention also relates to a method of adapting power rotation angle of an electrical inverter to match the unknown grid impedance at the point of connection.
