Abstract: A solar energy generation system a measurement module and a positioning method are disclosed herein. The positioning method is adaptable to a power generation system having AC generation modules. Each of the AC generation modules generates an output current and is electrically connected to each other in a power-supply network. The positioning method includes the following operations: (a) measuring AC currents or node voltages generated by the AC generation modules at different positions in the power-supply network to obtain current parameters or voltage parameters; and (b) determining a sequence of relative positions of the AC generation modules by calculating the current parameters or the voltage parameters.

Abstract: An inverting apparatus and a control method thereof are disclosed herein. The inverting apparatus includes an inverter. The inverter is configured to convert electrical energy to an output current so as to generate an output terminal voltage. When the output current increases, the output terminal voltage increases correspondingly. The inverter includes a control unit. When the output terminal voltage increases and falls within an alert range, the control unit is configured to control the inverter to decrease the output current or maintain the current output current so as to prevent the output terminal voltage from increasing and exceeding a voltage threshold value that causes the inverter to fall into a trip protection mechanism.
