The photovoltaic operation and maintenance management system aims to provide intelligent management tools for photovoltaic power generation companies or individuals. By collecting and transmitting data from photovoltaic power plants, storing and processing information, and conducting intelligent analysis and prediction, the system enables power plant managers to more accurately predict potential events in power plant operation and management. It allows them to schedule resources in a more timely manner and take prompt and effective measures for diversion, prevention, and handling. This ensures the effective operation and management of the photovoltaic power plant. The system incorporates a photovoltaic optimizer function, which improves the overall efficiency of the photovoltaic power generation system, reduces power losses between components, and provides more accurate data monitoring and fault diagnosis.
