Abstract
This application relates to the field of power technologies, and provides a photovoltaic system, which can increase a working voltage of a photovoltaic string. The photovoltaic system includes an adapter circuit, a first photovoltaic string, a second photovoltaic string, and a controller. The controller includes an inverter or a combiner box. The first photovoltaic string and the second photovoltaic string are configured to provide electric energy for the controller. The adapter circuit is configured to be connected to the first photovoltaic string in series, and further configured to connect the second photovoltaic string to the first photovoltaic string in series when a voltage of the first photovoltaic string is lower than a preset threshold.
