Problems solved by technology

[0003] However, the existing photovoltaic power station monitoring system is mainly provided by the inverter manufacturer with the equipment. It mainly starts from the inverter of the factory to monitor some parameters of the power station operation. It is difficult or impossible to directly control the operation status of the inverter, and it is also impossible to obtain Information and control of other equipment, because it is impossible to realize complete and unified real-time monitoring and control of photovoltaic power plants
