As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments such as sun exposure, rain, humidity, and sandstorms for a long time. The insulation layer of the cables is prone to aging and damage, the junction box is prone to water leakage, and the grounding device is prone to corrosion and failure, which can lead to safety accidents such as leakage, short circuit, electric shock, and lightning strikes, seriously threatening personnel safety and the stable operation of the power plant. Traditional testing equipment has a single function, complicated operation, and weak anti-interference ability, requiring multiple instruments to be carried back and forth for operation, making it difficult to meet the electrical safety testing needs of photovoltaic power plants in all scenarios. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has launched the LXH601 Insulation and Grounding Comprehensive Tester, which provides a one-stop solution for insulation and grounding safety testing in photovoltaic power plants with integrated design, high-precision detection performance, and intelligent operation experience, safeguarding the safe and efficient development of the photovoltaic industry.

Traditional photovoltaic electrical safety testing requires carrying multiple devices such as insulation resistance tester, grounding resistance tester, conductivity tester, voltage tester, etc. The types of devices are diverse, heavy, inconvenient to carry, and the operation methods and wiring specifications of different devices vary. Frequent switching of devices not only reduces work efficiency, but also easily leads to detection errors or safety hazards due to wiring errors. At the same time, traditional equipment has weak anti-interference ability, and in complex outdoor electromagnetic environments, the stability of detection data is poor, making it difficult to accurately reflect the true safety status of electrical equipment. LXH601 breaks the limitations of traditional equipment's "one machine, one use" approach, achieving multi-functional integrated testing. One device can complete the comprehensive electrical safety inspection of photovoltaic power plants, completely solving the pain points of traditional equipment and greatly improving the efficiency of operation and maintenance inspection.

LXH601 integrates more than 10 core functions, including insulation resistance testing, grounding resistance testing, conduction testing, voltage detection, polarity testing, Voc/Lsc testing, and insulation fault location. Its functions comprehensively cover the safety testing needs of all electrical components such as photovoltaic power plant modules, inverters, combiner boxes, cable lines, and grounding devices. The equipment is designed specifically for the 1500V high-voltage system of photovoltaic power plants. The insulation resistance test range covers 0.1M Ω -10G Ω, the grounding resistance test range is 0.01 Ω -100 Ω, and the voltage detection range is 0-1500V, accurately adapting to the detection scenarios of high-voltage photovoltaic systems; The accuracy of insulation testing is ± 5%, and the accuracy of grounding testing is ± 2%. The data is accurate and reliable, meeting the requirements of international and domestic testing standards such as IEC 61557 and GB/T 17949, providing authoritative data support for electrical safety assessment.

In terms of intelligent and convenient design, LXH601 fully meets the operational needs of outdoor photovoltaic power plants. The device adopts a large-sized high-definition LCD display screen, with a clear and easy to understand Chinese operation interface, menu style navigation, and convenient function switching, making it easy for beginners to get started and operate quickly; Equipped with intelligent wiring prompt function, the screen displays wiring diagrams in real time to avoid wiring errors; Support one click detection, no need for complex parameter settings, quick detection upon startup, single point detection time reduced to less than 1 minute, with an efficiency improvement of over 60% compared to traditional multi device detection; Built in large capacity storage, capable of storing tens of thousands of sets of detection data, supporting data query, export, and printing, facilitating data traceability and report generation, meeting the needs of power plant operation and maintenance file management and third-party detection data delivery.

To adapt to complex outdoor work environments, LXH601 strictly controls stability and durability. The equipment adopts industrial grade components with strong electromagnetic interference resistance, and the data is stable and reliable in outdoor strong electromagnetic environments; The body is sturdy and durable, with dust-proof, moisture-proof, and shockproof designs, suitable for working in harsh environments such as sun exposure, rain, and sandstorms; Adopting a portable and lightweight design, paired with a dedicated protective bag, the host and accessories are classified and stored, making it easy for a single person to carry and transport. It can be quickly deployed in various photovoltaic power plant scenarios such as mountains, rooftops, and water surfaces; Equipped with long-lasting lithium batteries, it has a long battery life and supports long-term operation in outdoor environments without power, meeting the needs of all day inspections.

LXH601 is not only suitable for the photovoltaic industry, but can also be widely used in multiple fields such as power, communication, construction, and industrial manufacturing. It is used for insulation testing of electrical equipment, performance evaluation of grounding systems, and troubleshooting of power lines. It has strong versatility and high cost-effectiveness. In the field of photovoltaics, this equipment has been widely used in scenarios such as grid connection acceptance of power plants, daily operation and maintenance inspections, fault diagnosis, and annual safety testing. It is highly recognized by photovoltaic power plant operators, operation and maintenance enterprises, engineering installation companies, and third-party testing institutions.

In the future, LAILX in Suzhou will continue to focus on innovation in photovoltaic electrical safety testing technology, continuously optimize the performance of LXH601 products, improve functional configuration, enhance intelligence level, and provide more efficient, accurate, and convenient electrical safety testing solutions for the photovoltaic industry. The launch of LXH601 insulation grounding comprehensive tester will help photovoltaic power plants build a full process electrical safety control system, effectively prevent electrical safety accidents, ensure stable operation of power plants, and promote the safe, healthy, and sustainable development of the photovoltaic industry.
