The application of industrial and commercial rooftop distributed photovoltaic power stations is the most widely used photovoltaic power generation system, which is a photovoltaic power generation project built on the roofs of urban buildings. This type of project must be connected to the public power grid, which together provides power to factories, shopping malls, and other places.
Household photovoltaic power generation is a small solar power generation device installed on the roof of a household. The energy of photovoltaic power plants comes entirely from the sun, and the process of producing electricity is very green and environmentally friendly. And different installation modes will be adopted based on the shape and nature of the roof, with flexible customized installation methods and sizes, without occupying and effectively utilizing land.
But as more and more households choose household photovoltaic power plants, how to further improve the safety and revenue guarantee of photovoltaic power plants has become a key focus that the industry urgently needs to break through, especially in the prevention of power plant fire accidents
Retrofit of arc protection for photovoltaic power plants
Distributed photovoltaic power stations are built on residential or commercial rooftops. Once a fire occurs in the power plant, it will have immeasurable serious consequences for personal safety and property. According to the analysis of fire accidents, fire accidents caused by DC arcs account for a large proportion. In order to prevent fire accidents caused by DC arcs, it is urgent to take arc technology prevention measures to prevent them.
Retrofit of photovoltaic power station combiner box
The DC combiner box of photovoltaic power plants can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the range of power outage in case of photovoltaic system failure. After several years of operation, the old power station will appear: the insulation of components is aging, the communication failure of the department cannot communicate with the background, and the operation status of the equipment cannot be monitored in real time, leading to the failure of the combiner box cannot be found in time, affecting the normal management of the power station and affecting the power generation efficiency. Therefore, the renovation of the combiner box is urgent.
