Zusammenfassung:The present application provides a photovoltaic system and an update method for networking of an optimizer thereof. The update method for networking of the optimizer comprises: first, an inverter obtains a serial number of an optimizer in each photovoltaic string within a preset time period, and determines whether an optimizer corresponding to each serial number has completed networking; if at least one optimizer has not completed networking, it is indicated that the optimizer is a replaced or newly added optimizer, and at this time, the inverter controls or keeps the operation of an optimizer that has completed networking, and controls the active bypass of an optimizer that has not completed networking; and then, the inverter compares the output current of each optimizer that has not completed networking with the current of each photovoltaic string to determine a photovoltaic string to which each optimizer that has not completed networking belongs. In this way, the automatic update of the networking of the r
