Low-voltage electrical appliances are required in all aspects of large-scale photovoltaic grid-connected power generation systems. For example, photovoltaic arrays require PLC, reversible contactors, photovoltaic combiner boxes, AC power distribution panels, transformers and other equipment. Specifically, in order to reduce photovoltaic components and The number of connections between the inverters is convenient for maintenance, reliability, and cost reduction. Generally, a DC converging device is added between the photovoltaic module and the inverter.

　　 New energy construction brings opportunities for low-voltage electrical appliances

"The application of distributed power generation technology can bring many benefits, but it is also accompanied by adverse effects such as randomness, intermittentness, and difficulty in regulation. Therefore, it is often necessary to be equipped with other regulatory means to assist. Renewable energy power generation and high efficiency based on fossil energy Power generation will be widely used in the power system. This trend will lead to changes in the structure, operation, management, and control methods of the power grid. The power storage system will become a key equipment in the future power grid." "Distributed power generation, energy storage and microgrid technology and equipment" forum, said Sun Changji, chairman of the China Electrotechnical Society.

　　 The development of smart grid construction and new energy has brought new opportunities for my country's low-voltage electrical appliance industry. At present, the smart grid has entered an important period of construction. my country’s urbanization is proceeding rapidly, and the intelligent construction of urban and rural distribution networks will also be fully launched. Smart grids and smart complete sets of equipment, smart power distribution, and control systems will usher in a golden development period. , A large number of new energy power generation continues to grow, bringing opportunities and challenges to my country's low-voltage electrical industry.

　　 From a technical perspective, in the context of industrial restructuring and the realization of low-carbon economic development, a new generation of energy-saving, material-saving, and high-performance low-voltage electrical products will have greater development, and market demand will become increasingly strong. This is also a low-voltage electrical appliance. The transformation and upgrading of the industry provides a rare opportunity. At the same time, with the continuous development of low-voltage electrical appliances production technology, a new generation of intelligent low-voltage electrical appliances featuring intelligence, modularity, and communication capabilities will become mainstream products in the market, and the market share of high-end low-voltage electrical appliances will further expand.
