    摘要： An IV curve scan method for a photovoltaic module and an optimizer are provided. The optimizer receives an IV curve scan signal and controls an output voltage of the photovoltaic module corresponding to the IV curve scan signal to change from an open-circuit voltage to a preset minimum voltage according to a preset rule, while photovoltaic module connected to another optimizer can still operate normally, so that the system can operate normally. Then the optimizer uploads IV curve data of the photovoltaic module corresponding to the IV curve scan signal, to complete an IV curve scan on a single photovoltaic module.
