Xiamen Kehua Digital Energy Co., Ltd. has applied for a patent related to the startup control of photovoltaic inverters, aiming to simplify the maintenance process for staff. The application was filed on March 2025 and is titled “Startup Control Method and Device for Photovoltaic Inverters, Photovoltaic Inverter, and Storage Medium”, with the publication number CN120074211A.
The patent summary indicates that the invention provides a method, device, and storage medium for controlling the startup of photovoltaic inverters. The method includes the following steps: once the photovoltaic inverter is powered on, it checks whether the inverter meets the first and second preset self-start conditions. The first preset self-start condition is determined based on the last control status of the inverter by the upper computer, while the second condition relies on the voltage of the photovoltaic array connected to the inverter and the starting voltage.
If both the first and second preset self-start conditions are satisfied, the inverter will be instructed to power on. Conversely, if at least one of the conditions is not met, the inverter will remain in a powered-off state.
