Abstract: A method for component voltage limitation, and an apparatus and a system for applying the same. At least one photovoltaic cell in a photovoltaic-cell string is controlled to operate in a voltage-limited mode, in response to receiving an instruction for enabling voltage limitation. Thereby, the voltage of the photovoltaic-cell string is reduced. A quantity of photovoltaic modules connected in series can be increased, while a highest voltage of the system is guaranteed not to exceed a corresponding requirement. A system cost is reduced. The photovoltaic cell operating in the voltage-limited mode is controlled to resume a normal output, in response to receiving the instruction for suspending voltage limitation. The output voltage of the photovoltaic-cell string is increased. Thereby, a rate of utilization on a direct voltage, and a PVIR of DC/AC are improved for the photovoltaic system.
