How do I choose an SPD for my solar system?
21/ November 2023
How do I choose an SPD for my solar system?
Solar arrays are also electronic devices and therefore can be damaged by surges as well. Solar panels are particularly vulnerable to lightning strikes due to their large surface area and placement in exposed locations, such as on rooftops or the ground in open spaces. So it is very important to protect it from lightning or surge damage. To choose the appropriate surge protective devices model for your solar/photovoltaic system, the following points should be kept in mind: 1. Lightning circular flash density; 2. The operating temperature of the system; 3. System voltage; 4. The rated short-circuit current of the system; 5. The waveform level to be protected. 6. Nominal discharge current. Since its establishment in 2006, Jinli Electric has been deeply involved in surge protectors for nearly two decades, adhering to the corporate mission of "creating the world's first lightning protection brand to protect users from lightning intrusion". The independently developed and produced photovoltaic surge protectors, lightning arresters, backup protectors, etc. are at the forefront of the industry in terms of quality and performance. Jinli Electric’s photovoltaic surge protectors System voltages are: 600v 800v 1000v 1500v Working temperature: -40C°~+85C° Waveforms include 10/350us 8/20us The nominal discharge current is 20KA. Can meet the requirements of most solar systems, thereby providing a safer, more stable, and more efficient operating environment for photovoltaic power plants.
  • Introduction to Jinli low voltage surge protector types
    14/ November 2023
    Introduction to Jinli low voltage surge protector types
    Anhui Jinli Electrical Technology Co., Ltd. currently produces three types of low-voltage surge protectors: T1(Surge protectors) • This SPD device is installed on the line side of the main service entrance. • Type-1 SPD features 10/350 μs current wave for outdoor applications. • It protects against external surges caused by lightning strikes or due to switching of common capacitor banks. It is considered the first line of defense for your home or office. • Built-in alarm system indicates when equipment needs to be replaced based on its life cycle. It is also called a secondary lightning arrester. T2 (Surge protectors) • This SPD device is installed on the load side of the main service entrance. • T2 SPD is characterized by an 8/20 μs current wave. • Used to protect branch circuits or service entrances from residual lightning energy, surges due to motors, and other surges. •Its main function is to limit transient voltages and protect sensitive electronic devices and MP/Mc-based motherboards. • It is used in commercial and industrial applications. T3 (Surge protectors) Can be used to add extra protection to appliances already covered by Type 1 or Type 2 SPD. Recommended installation: Close to the equipment to be protected, especially if the cable length from the switch panel exceeds 10 meters. Jinli Electric has 17 years of experience in manufacturing surge protectors since its establishment in 2006. It has a wide range of SPD and complete certifications. Continue to make contributions to the lightning protection of enterprises.

  • Anhui Jinli assists in intelligent operation and maintenance of photovoltaic power plants

    Anhui Jinli assists in intelligent operation and maintenance of photovoltaic power plants
    With the rapid development of renewable energy, photovoltaic power stations have been widely used as a clean energy power generation method. The operation and maintenance management of photovoltaic power stations realizes functions such as operating data monitoring, fault monitoring and diagnosis, and on-site security management and control through the smart photovoltaic operation and maintenance management platform. However, intelligent monitoring in the lightning protection sector is still a blind spot in existing photovoltaic projects. Since photovoltaic power stations are exposed to a large area of the surrounding open outdoor environment, they face a greater risk of lightning strikes. Lightning strikes may not only cause equipment damage and economic losses due to the inability to connect to the grid for power generation but may also threaten the safety of power station operation and maintenance personnel, posing huge challenges to power station operation and maintenance. To cope with these challenges, Anhui Jinli proposed a "photovoltaic power station smart lightning protection system solution". This solution integrates key technologies such as SPD online monitoring, lightning early warning online monitoring, and grounding resistance online monitoring, aiming to provide photovoltaic power stations with comprehensive lightning protection measures and realize intelligent monitoring and management. The smart lightning protection system is a solution that integrates advanced technology and intelligent management methods. It aims to provide comprehensive lightning protection measures for photovoltaic power stations and provide non-periodic operation and maintenance guidance and suggestions to the site. The system monitors and analyzes equipment status, lightning activity, and grounding system conditions in real time through key technologies such as surge protector online monitoring, lightning early warning online monitoring, and grounding resistance online monitoring. Through intelligent algorithms and models, the system can predict the changing trend of lightning risks and the changing trend of the surge protector throughout its life, and send out early warning signals in time to help operators take necessary protective measures. By introducing smart lightning protection systems, photovoltaic power stations can improve their capabilities, reduce lightning strikes, reduce daily maintenance of lightning protection equipment, and ensure the safe operation and sustainable development of power stations. This intelligent lightning protection solution will provide a safer, more stable, and efficient operating environment for photovoltaic power plants.
