Abstract
A photovoltaic system includes at least one first direct current module, an electromagnetic apparatus, a direct current switch-on/off apparatus, and a second direct current module. First connection ends of all first direct current modules in the at least one first direct current module are connected in parallel and then connected to a first connection end of the electromagnetic apparatus, a second connection end and a third connection end of the electromagnetic apparatus are connected to a first connection end of the second direct current module by using the direct current switch-on/off apparatus, and second connection ends of all the first direct current modules are connected in parallel and then connected to a second connection end of the second direct current module. The electromagnetic apparatus is configured to control the direct current switch-on/off apparatus to disconnect a loop between each first direct current module and the second direct current module.
