Kehua Data Energy has applied for a patent related to the control of photovoltaic inverter startup, aimed at reducing the complexity of maintenance for staff. According to information from the State Intellectual Property Office, Xiamen Kehua Data Energy Technology Co., Ltd. submitted a patent entitled “Method and Device for Starting Control of Photovoltaic Inverters, Photovoltaic Inverter, and Storage Medium”, with publication number CN120074211A, filed on March 2025.
The patent summary indicates that this application provides a method and device for the startup control of photovoltaic inverters, as well as a photovoltaic inverter and storage medium. The method includes the following steps: when the photovoltaic inverter is powered on, it checks whether the inverter meets the first preset self-start condition and the second preset self-start condition. The first preset self-start condition is based on the last instance of the upper computer controlling the inverter’s power on and off, while the second preset self-start condition is determined by the voltage of the photovoltaic array connected to the inverter and the startup voltage.
If the inverter satisfies both the first and second preset self-start conditions, it will be powered on. Conversely, if it fails to meet at least one of these conditions, the inverter will remain in the off state.
