The present invention relates to a method for supplying at least one load with electrical power. The at least one load is in this case supplied with power from an electrical DC voltage source and/or an electrical AC voltage source. According to the invention, a method is provided for supplying electrical power, in particular for supplying electrical power in parallel with a power supply system on a low-voltage power supply system to at least one load, which method is carried out in an electrical installation which has at least an electrical DC voltage source, an inverter, in particular a bidirectional inverter, a measurement apparatus, in particular a power meter which measures an electrical power of the at least one load, an electrical AC voltage source and a control element, wherein the control element has at least one evaluation unit which analyzes measurement data from the at least one measurement apparatus to determine whether the load power is greater than the power available from the DC voltage source, and wherein, when this condition is satisfied, the control element makes an electrically conductive connection (line connection), in particular by means of a switch, between at least the AC voltage source and the at least one load. |
