On June 13th, the 17th (2024) International Solar Photovoltaic and Smart Energy (Shanghai) Conference was grandly held at the National Convention and Exhibition Center. This time, SNEC attracted more than 3600 companies from around the world to participate. As a long-time exhibitor of SNEC, Anhui Jinli made a grand debut with its photovoltaic storage products, solutions, and related technologies.

  Jinli Electric has been rooted in the photovoltaic industry for more than ten years, and brought new products (DC2000V modular SPD, DC2000VPCBSPD, line lightning arrester acquisition terminals and collection units) to shine on the 6.1H-D520,whichreceiving numerous inquiries from photovoltaic storage enthusiasts and international friends.

DC 2000V modular SPD and PCB SPD

  With the continuous innovation of photovoltaic technology and material technology, the efficiency of batteries, insulation level of materials, and manufacturing process technology have made rapid progress, making higher system voltages possible. At the same time, the increase in system power density is conducive to reducing the cost ofPV systems, making the 2000V photovoltaic power station systemto bethe current development trend. The 2000V modular SPD used in combiner boxes and thePCB SPD used in inverters have emerged, and Jinli has mature SPD products supporting the DC2000VPVsystem.

Energy storage lightning protection boxes and intelligent lightning protection systems lead the new trend of lightning protection

  The energy storage dedicated intelligent lightning protection box is a high-end lightning protection unit that uses high current and low residual voltage functions internally, and utilizes modern power electronics technology to monitor the operation status of the lightning protection unit, store and analyze lightning data, and provide a human-machine friendly interface. The intelligent lightning protection box for energy storage is called the "reliable nanny" of the battery compartment, which integrates "high current", "low residual voltage", and "intelligence" technology. It is installed on the side of the junction box in the battery prefabricated compartment to achieve the best lightning overvoltage protection for the battery prefabricated compartment.

  The intelligent lightning protection system is a solution that integrates advanced technology and intelligent management methods, aiming to provide comprehensive lightning protection measures for photovoltaic power stations and provide non periodic operation and maintenance guidance suggestions for the site. The system utilizes key technologies such as SPD online monitoring, lightning warning online monitoring, and grounding resistance online monitoring to monitor and analyze equipment status, lightning activity, and grounding system conditions in real time. Through intelligent algorithms and models, the system is able to predict the trend of lightning risk and the trend of SPD throughout its lifespan, and timely issue warning signals to help operation and maintenance personnel take necessary protective measures.

Line type lightning arrester monitoring instrument and collection unit

  The online monitoring instrument for lightning arresters on transmission towers is designed with a low-power microcontroller, taking into account the application environment. The short-range online monitoring instrument for line type lightning arresters adopts LoRa wireless communication, with a transmission distance of up to 3km. The remote collection unit can simultaneously collect and transmit data from multiple monitoring instruments, which can be transmitted through wired optical fiber, wireless 4G, etc. It has the function of monitoring the number of actions and leakage current, solving the problem of inability to monitor the performance of lightning arresters on transmission towers.

  SNEC 2024 has come to a successful end. Based on the development trend of the photovoltaic industry and the solutions to on-site application problems, we are constantly developing new products, improving ourselves, and creating the world's best lightning protection brand. This is the driving force for our continuous progress, safeguarding the safe operation of photovoltaic storage. Finally, we sincerely thank every customer and industry enthusiast who supports and cares about Jinli.
