Abstract
The application provides a photovoltaic inverter system, an automatic locating method of RSDs and a fault control method thereof. The automatic locating method comprises turning off all RSDs and sampling a voltage of an output end of each RSD as a first voltage before an inverter operates; turning on any one of the RSDs and sampling a voltage of the output end of each RSD as a second voltage, determining all RSDs in a photovoltaic module string to which the RSD in a turned-on state belongs according to the first voltage and the second voltage, and repeating the above control method for any one of the RSDs outside the photovoltaic module string to which the determined RSDs belong until corresponding connection relations between all RSDs and all photovoltaic module strings are determined.
