Recently, Jiangsu Zerun New Energy Technology Co., Ltd. (hereinafter referred to as Zerun New Energy) updated the draft of the listing prospectus and plans to be listed on the GEM of the Shenzhen Stock Exchange, planning to raise 7200 million yuan, for photovoltaic module general and intelligent junction box expansion project, new energy vehicle auxiliary power battery box construction project, R & D center construction project, replenishment of working capital.
According to the IPO prospectus of Zerun New Energy, Zerun New Energy is a high-tech enterprise focusing on the field of new energy electrical connection, protection and intelligent technology, specializing in providing integrated solutions for photovoltaic module junction box products, and a national-level specialized and new "little giant" enterprise.
Zerun New Energy's current main products are photovoltaic module junction boxes, which can be divided into universal junction boxes and intelligent junction boxes according to whether they contain intelligent chip modules. The universal junction box does not contain a smart chip, and its main functions include connection and automatic protection functions; In addition to connection and automatic protection functions, the intelligent junction box can also realize refined control functions such as intelligent optimization of power generation efficiency, intelligent shutdown and intelligent monitoring of photovoltaic modules.
Specifically, the universal junction box is the most common and widely used photovoltaic module junction box product, which is composed of three parts: box, cable and connector, of which the box is the main part and the core component to realize the connection and automatic protection function.
Under the normal operation of the photovoltaic system, the junction box of the photovoltaic module plays a connection function, and the current generated in the panel is connected to the entire photovoltaic system through the busbar, conductive devices, cables and connectors; When the hot spot effect occurs in the module, the automatic protection device connected in parallel with the circuit in the junction box of the photovoltaic module can play an automatic protection role, so that the current can bypass the cells affected by the hot spot, effectively reduce the power loss and safety risks caused by the hot spot effect, and play a role in protecting the stable and safe operation of the photovoltaic system.
In terms of intelligent junction box, Zerun New Energy's intelligent junction box product is the application of power electronics technology (MLPE) in the field of solar photovoltaic, on the basis of the connection and protection functions of the universal junction box, the refined control of photovoltaic modules is realized through intelligent chips, such as adding intelligent optimization modules to eliminate module hot spots, delay module attenuation, improve module service life, reduce module mismatch, and improve photovoltaic power generation efficiency; The addition of an intelligent shutdown module can quickly cut off the connection of components, implement safety rescue for the power station, and improve the overall safety of the power station. The intelligent monitoring module can be added to monitor the situation of the photovoltaic circuit system in real time.
Relying on its comprehensive advantages in design and development, quality control and service response, Zerun New Energy has established good cooperative relations with internationally renowned photovoltaic module companies such as Maxeon and Sonnenkraft, TCL Zhonghuan, EGing Optoelectronics, Runyang Co., Ltd., Seraphim, Haitai New Energy, Zhongqing Photovoltaic and other leading domestic photovoltaic module manufacturers, and the final products are widely used in solar photovoltaic power stations at home and abroad.
