As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments for a long time, and problems such as aging of cable insulation and corrosion failure of grounding devices can easily cause safety accidents such as leakage, short circuits, and lightning strikes, seriously threatening personnel safety and stable equipment operation. Traditional detection equipment has a single function and is cumbersome to operate. It requires the cooperation of multiple instruments to complete insulation, grounding, and other tests, resulting in low efficiency and high costs. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the pain points of photovoltaic electrical safety testing and has launched the LXH601 insulation grounding comprehensive tester, which integrates eight core functions into one machine. With integrated design, high-precision testing, and intelligent operation, it provides a one-stop solution for the electrical safety of photovoltaic power plants, strengthens the safety defense line, and empowers operation and maintenance to improve quality and efficiency. Leakage current test

The LXH601 Insulation Grounding Comprehensive Tester is a multifunctional safety testing equipment developed by LAILX specifically for photovoltaic power plants, power systems, and industrial electrical fields. It completely breaks the limitations of traditional equipment's "one machine, one use" approach and achieves "one device, full item testing". The whole machine integrates eight core functions: insulation resistance testing, grounding resistance testing, conduction testing, voltage detection, polarity testing, Voc testing, Lsc testing, and insulation fault location. It does not require frequent switching of equipment and wiring, and can complete comprehensive electrical safety testing of photovoltaic modules, inverters, combiner boxes, cable lines, grounding devices, etc. in one deployment. The efficiency of a single inspection is increased by more than 40%, greatly reducing the workload of operation and maintenance personnel and equipment procurement costs. Whether it is daily operation and maintenance safety inspection of power stations, grid connection acceptance electrical testing, or post fault insulation and grounding fault location, LXH601 can be competent and become a versatile equipment for photovoltaic electrical safety testing.

High precision detection performance, suitable for high-voltage scenarios, ensuring accurate and reliable data. In terms of insulation resistance testing, the equipment supports 0-1500V DC voltage detection and is accurately adapted to the current mainstream 1500V high-voltage photovoltaic system. It has a wide measurement range and high accuracy, and can accurately detect insulation layer aging, damage, moisture and other issues of cables, components, inverters and other equipment. The insulation resistance measurement accuracy reaches ± 5%, ensuring accurate and error free insulation state evaluation. The grounding resistance test adopts the four pole method measurement technology, which can effectively eliminate the interference of soil resistance and lead resistance, with a measurement accuracy of ± 2%. It accurately detects faults such as corrosion, fracture, and poor connection of the grounding device, ensures reliable conduction of the grounding system, timely discharges fault currents, and prevents lightning strikes and electric shock risks. At the same time, it supports 200mA protection conductor continuity testing to verify the reliability of the grounding conductor connection; Equipped with polarity testing function to prevent equipment damage caused by reverse polarity connection, ensuring comprehensive safety of the electrical system.

Intelligent fault location function, quickly lock the location of hidden dangers, and improve operation and maintenance efficiency. The LXH601 is equipped with an intelligent insulation fault location module, which can accurately locate the insulation fault position in photovoltaic strings and cable lines. Through percentage value positioning technology, the specific location of the fault in the string is intuitively displayed in the intelligent photovoltaic APP, without the need for step-by-step troubleshooting, greatly reducing the troubleshooting time. Support disconnection and connection testing verification, by disconnecting suspected faulty components or optimizers, quickly identify the fault location and improve fault handling efficiency. The device has built-in large capacity storage, which can store thousands of sets of test data. It supports one click data export and automatic report generation. The format can be customized to meet the needs of power plant operation and maintenance archives retention, third-party testing report issuance, etc. At the same time, it is equipped with a high-definition color touch screen, a simple and intuitive operation interface, bilingual display in Chinese and English, allowing beginners to quickly get started and operate without professional training, reducing the threshold for use.

Outdoor adaptation and safety design, balancing practicality and safety. LXH601 adopts an integrated portable design, with a compact and lightweight body, paired with a high-strength protective box, which is shockproof, waterproof, and dustproof. It can be easily carried to various outdoor photovoltaic power plants such as mountains, deserts, and rooftops, and can be carried and operated by a single person. The body adopts a waterproof and dustproof design, which can adapt to extreme temperature environments ranging from -20 ℃ to 60 ℃. It is not afraid of outdoor sun exposure, rain, and sandstorms, and can operate stably under harsh working conditions. In terms of safety performance, the equipment has overvoltage, overcurrent, and short-circuit protection functions, high insulation protection level, and eliminates the risk of leakage; The high-voltage testing end adopts an anti electric shock design to ensure the safety of operators during the wiring process and adapt to the requirements of high-voltage detection scenarios. At the same time, it adopts a low-power design and is equipped with a large capacity lithium battery, which has a long battery life and meets the outdoor inspection needs all day long, without the need for frequent charging.

Multi scenario adaptation, expanding application boundaries, and enhancing device value. In addition to photovoltaic power stations, LXH601 can also be widely used in power distribution networks, industrial plant electrical systems, new energy storage power stations, charging piles, and other scenarios to meet the insulation, grounding, and conductivity detection needs of various electrical equipment. In the power distribution network, insulation aging and grounding faults of the lines can be detected; In industrial plants, electrical safety hazards such as motors, distribution cabinets, and circuits can be investigated; In the field of energy storage power stations and charging piles, it can ensure the safe operation of high-voltage electrical systems, adapt to the electrical safety testing needs of multiple industries, and has strong universality.

With integrated functions, high-precision detection, and reliable quality, the LXH601 insulation grounding comprehensive tester has been widely used in major photovoltaic power stations, power enterprises, and third-party testing institutions in China, and has been highly recognized by industry customers. In the future, LAILX in Suzhou will continue to deepen its expertise in the field of electrical safety testing, continuously optimize product performance, upgrade intelligent functions, and launch safety testing equipment that better meets industry needs, helping the safe, stable, and efficient development of the photovoltaic and power industries.
