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.

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.

The types of loads we connect to a building’s electrical system today vary greatly from what may have been connected 50 years ago. Today’s buildings rely heavily on electronics, communications, and microprocessors for some of the most basic functions. These include electronic controls built into a compact fluorescent or LED (light-emitting diode) light bulb, as well as sophisticated building control and automation systems. Automated systems are incorporated into a building’s emergency system as well. This increased use of electronics demands an electrical infrastructure that takes into account the increased sensitivity of electronic loads to voltage transients that can enter the electrical system. These transients can enter through external sources such as lightning and other electrical faults occurring outside the building, as well as through the routine switching of loads inside the building that occur as part of normal operations. 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 No. 1 lightning protection brand to protect users from lightning intrusion". The independently developed and produced surge protectors, lightning arresters, backup protectors, etc. are at the forefront of the industry in terms of quality and performance and are very effective in mitigating transient overvoltage. This prevents equipment damage or malfunction due to excessive voltage caused by switching, direct or indirect lightning strikes, or crossing of high-voltage power lines and low-voltage power lines. Better ensure the safety of the building itself and electrical equipment. Transient events are by their nature very short, fast events, typically in the range of 5 to 200 microseconds. Momentary increases in voltage can create permanent conductive paths that can cause damage to electrical components. Today we need to better apply surge protectors to buildings to protect the safety of people and property.
