The invention relates to a method for recognizing the operational state of a load ( 10 ) connected to the output ( 6,7 ) of an island inverter ( 1 ). A load recognition signal (S<SUB>L</SUB>) is applied at specific moments in time to the output ( 6, 7 ) of the island inverter ( 1 ), during which specific electric parameters are measured on the island inverter ( 1 ), enabling the operational state of the load ( 10 ) to be determined, wherein the island inverter ( 1 ), when the load ( 10 ) is activated, is switched from a possible standby mode into a permanent operation mode and, when the load is deactivated ( 10 ), the island inverter is switched from a possible permanent operation mode to a standby mode. The invention also relates to an island inverter ( 1 ). In order to ensure reliable recognition of all possible collected loads ( 10 ), a load recognition signal (S<SUB>L</SUB>) with parameters (T, d, A, H, f) that are modified at least according to the type of load ( 10 ) is applied to the output ( 6,7 ) of the island inverter ( 1 ). |
