摘要： A system for distributing locally generated energy from at least one renewable DC source to a plurality of local load units of the system, including, for each load unit: an input terminal configured to connect to a grid, and an output terminal configured to connect to at least one load. Further for each load the system includes an inverter including an inverter input and an inverter output, wherein the inverter input is connected to the at least one renewable DC source and the inverter output is connected to the input terminal and to the output terminal of the respective load unit, and wherein the inverter is configured to convert a direct current at the inverter input into an alternating current at the inverter output. The system also includes a power meter including a power meter input connected to the input terminal of the respective load unit, wherein the power meter is configured to determine a current power consumption from the grid, and wherein the power meter includes a power meter output connected to the inverter of the respective load unit, and wherein the power meter is configured to transmit data relating to the current power consumption from the grid to the inverter. The inverter of the respective load unit is configured to determine an input DC voltage applied to its inverter input and to determine a power to be currently converted from the applied input DC voltage and the current power consumption data transmitted thereto.

摘要： A method for converting DC power from a source into AC power by means of an inverter which includes three bridge branches, each having a phase output, is described. During grid-connected operation, the bridge branches are actuated in such a way that the AC power is fed, as three-phase grid-compliant power, into a grid. During emergency operation of the inverter, the AC power is provided as single-phase island grid by two of the three bridge branches at the phase outputs thereof, wherein the inverter is disconnected from the grid.
