The role of DC combiner boxes in centralized photovoltaic power plants
1. Overview of Centralized Photovoltaic Power Stations
The centralized photovoltaic power station is the country's utilization of the desert, and it is recommended to concentrate on large-scale photovoltaic power stations.
2. Structure of centralized photovoltaic power station
3. DC combiner box
In the solar photovoltaic power generation system, the combiner box will be used, also known as the solar combiner box, the solar photovoltaic combiner box, the photovoltaic array lightning protection combiner box, the solar power generation combiner box, the photovoltaic power generation combiner box, and the photovoltaic lightning protection combiner box.
In the solar photovoltaic power generation system, in order to reduce the connection between the solar photovoltaic cell array and the inverter, a combiner box is used. Combined with years of experience in lightning protection system design, a variety of open-number combiner boxes have been developed. Users can connect a certain number of photovoltaic cells with the same specifications in series to form photovoltaic arrays, and then connect several photovoltaic arrays in parallel to the photovoltaic lightning protection box. DC power distribution cabinets, photovoltaic inverters, and AC power distribution cabinets are used together to form a complete photovoltaic power generation system, which can be connected to the grid. In order to improve the reliability and practicability of the system, the photovoltaic lightning protection combiner box is equipped with photovoltaic special DC lightning protection modules, DC fuses and circuit breakers, which are convenient for users to grasp the working conditions of photovoltaic cells in a timely and accurate manner and ensure solar photovoltaic power generation. The system works.
The role of the DC combiner box is to reduce the connection between the photovoltaic array and the inverter, optimize the system structure, and improve reliability and maintainability. While providing the lightning protection function of the bus, it also monitors the operating status of the photovoltaic panels.
