摘要： A method of converting a direct voltage generated by a decentralized power supply system into three-phase alternating voltage by means of a plurality of single-phase inverters (WR1-WR3), said alternating voltage being provided for supplying an electric mains, is intended to avoid inadmissible load unbalances using single-phase inverters. This is achieved in that, upon failure of one inverter (WR1-WR3), an asymmetrical power supply distribution is reduced by limiting the output of the other inverters. The method makes it possible to simplify three-phase voltage monitoring.

摘要： A method for determining a load capability of a direct current (“DC”) voltage source connectable to an alternating current (“AC”) power grid having a predetermined frequency via an inverter and a grid disconnect switch includes controlling, while the grid disconnect switch is in an open position, the inverter so as to convert a DC input voltage to a test frequency different than the predetermined frequency of the AC power grid so as to increase a test load acting on the DC voltage source above an internal consumption of the inverter at the predetermined frequency. The DC input voltage is measured while the grid disconnect switch is in the open position.
