With the accelerated development of the global photovoltaic industry towards scale and intelligence, photovoltaic power stations, as high-voltage electrical systems, are exposed to complex environments such as outdoor sun exposure, rain, wind and sand, and humidity for a long time. The insulation layer of components, inverters, combiner boxes, cables and other equipment is prone to aging and damage, and the grounding device is prone to corrosion and failure, which can lead to safety accidents such as leakage, electric shock, short circuit, lightning strikes, seriously threatening personnel safety, stable equipment operation, and power generation efficiency of the power station. Traditional electrical safety testing equipment generally suffers from pain points such as single functionality, cumbersome operation, the need to carry multiple devices, weak anti-interference ability, and low detection efficiency, making it difficult to meet the full scenario and multi-dimensional electrical safety testing needs of photovoltaic power plants. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of new energy testing for many years. Relying on its deep technical accumulation and the advantages of industry university research cooperation, it has launched the LXH601 insulation grounding comprehensive tester, which provides a one-stop solution for electrical safety testing of photovoltaic power plants with integrated design, high-precision testing, intelligent operation, and strong anti-interference ability. It lays a solid foundation for the safe operation of photovoltaic systems and empowers the safe and efficient development of the new energy industry. Leakage current test

As a multifunctional safety testing equipment developed by LAILX specifically for photovoltaic power plants, power systems, industrial electrical and other fields, LXH601 has focused on the core pain points of traditional testing equipment since its inception, breaking the limitations of "one machine, one use" and achieving the integration of eight core functions. One device can complete the comprehensive electrical safety testing of photovoltaic systems, completely solving the problems of traditional testing requiring multiple devices, frequent switching of wiring, and low efficiency. The equipment integrates core functions such as insulation resistance testing, grounding resistance testing, conduction testing, voltage detection, polarity testing, Voc testing, Lsc testing, and insulation fault location, without the need to replace equipment and wiring. Multiple key tests can be completed in one operation, greatly simplifying the operation and maintenance process and increasing the efficiency of a single inspection by more than 40%. Whether it is photovoltaic modules, inverters, combiner boxes, cable lines, grounding devices, or distribution systems, they can achieve comprehensive detection, accurately evaluate electrical safety status, and provide comprehensive data support for power station operation and maintenance.

At the same time, innovation supports the linkage of intelligent photovoltaic apps, which can remotely control devices, view real-time detection data, receive abnormal alarms through mobile apps. It can also locate the location of insulation faults through percentage values, accurately lock the specific section of the fault in the photovoltaic string, and greatly improve the efficiency of fault diagnosis. In addition, the device has polarity testing function, which can quickly determine whether the positive and negative connections of the circuit are correct, avoiding equipment damage caused by wiring errors.

In terms of durability and portability design, LXH601 is deeply tailored to outdoor photovoltaic power station operation and maintenance scenarios, balancing durability and flexibility. The whole machine adopts an industrial grade high-strength shell, which has dustproof, waterproof, and anti drop capabilities. It can adapt to harsh outdoor environments such as high temperature, humidity, high dust, and strong ultraviolet rays. It is not easily damaged after long-term use and has a long service life. The device adopts a lightweight design, with a compact and portable body and a dedicated protective box. It can be easily carried and transported by a single person, and is suitable for various complex photovoltaic power plant scenarios such as mountains, deserts, and distributed roofs. It does not rely on large auxiliary equipment and has high flexibility. Equipped with a large capacity lithium battery, it has a long battery life and supports all day outdoor operations, avoiding any impact on the detection progress due to power outages; Support fast charging, high charging efficiency, and ensure the continuity of operation and maintenance work.

With its core advantages of integrated integration, high-precision detection, intelligent operation, and strong environmental adaptation, LXH601 has been widely used in daily operation and maintenance, regular maintenance, completion acceptance, fault diagnosis, third-party safety testing and other scenarios of photovoltaic power plants. It is also suitable for insulation and grounding safety testing in power systems, industrial electrical, building electrical and other fields.
