With the widespread adoption of 1500V high-voltage photovoltaic systems, the electrical safety risks of photovoltaic power plants continue to escalate. Hidden dangers such as cable insulation aging, junction box water leakage and corrosion, loose grounding terminals, insulation damage and leakage can easily cause safety accidents such as arc ignition, equipment burning, and personnel electric shock, directly threatening the stable operation and asset safety of power plants. In the traditional testing mode, operation and maintenance personnel need to carry multiple devices such as insulation testers, grounding resistance testers, and conductivity testers. They need to repeatedly connect and frequently switch instruments on site, which makes the operation process cumbersome, time-consuming, and labor-intensive. Moreover, the calibration, maintenance, and procurement costs of multiple devices are high, and the data stability is poor in complex outdoor environments, making it difficult to meet the precise safety testing requirements of high-voltage photovoltaic systems. Suzhou LAILX hits the pain point of the industry by developing and launching the LXH601 insulation grounding comprehensive tester, which innovatively integrates multiple energy into one machine and innovates the photovoltaic electrical safety detection mode.

The biggest innovation highlight of LXH601 is the highly integrated photovoltaic electrical safety detection function. A single device integrates ten core functions, including insulation resistance testing, four wire grounding resistance testing, protective conductor continuity testing, AC/DC voltage detection, open circuit/short-circuit current testing, insulation fault location, and dielectric absorption ratio testing, completely bidding farewell to the cumbersome mode of traditional multi device stacking detection. In the past, completing a complete set of safety inspections for photovoltaic power plants required carrying multiple instruments and disassembling and connecting wires multiple times. Now, one LXH601 can complete all inspection items in one stop, reducing equipment carrying weight by 60% and improving on-site operation efficiency by more than 40%. At the same time, it significantly reduces the comprehensive operating costs of equipment procurement, storage, calibration, and maintenance for enterprises, with outstanding cost-effectiveness advantages.

In terms of core detection performance, the equipment accurately adapts to the detection standards of high-voltage photovoltaic systems. The insulation test supports multiple adjustable levels of 500V, 1000V, and 1500V, fully covering mainstream high and low voltage photovoltaic systems in the market. The insulation resistance range can reach up to 200M Ω, and the measurement accuracy is as high as ± 2%. It can accurately capture hidden problems such as insulation aging, moisture, and damage of cables, components, and combiner boxes, and predict leakage safety hazards in advance. Different from the traditional inefficient troubleshooting mode of equipment, LXH601 is equipped with LAILX's self-developed GFL insulation fault location technology, which can monitor the insulation status of the string to ground in real time. Through intelligent algorithms, it can quickly lock the insulation fault point and accurately locate problems such as cable damage, junction box water ingress, and component insulation failure. There is no need to disassemble and troubleshoot each section, greatly reducing the duration of fault maintenance and power station shutdown. The grounding test adopts the precise four wire method for measurement, effectively offsetting the interference of soil and lead resistance, accurately detecting hidden dangers such as corrosion, breakage, and poor contact of the grounding grid, ensuring the rapid discharge of fault current, and building a strong defense line against lightning, static electricity, and electric shock.

In response to the strong electromagnetic interference and complex outdoor working conditions of photovoltaic power plants, the equipment is equipped with digital adaptive filtering algorithms, which can automatically shield data interference caused by on-site electromagnetic, temperature and humidity fluctuations, eliminate numerical jumps and detection errors, and ensure accurate and stable data under complex working conditions without the need for repeated testing. The whole machine adopts an IP67 high protection design, with excellent dust, water, and earthquake resistance performance. It can operate stably in a wide temperature range of -10 ℃ to 50 ℃, and can easily cope with various harsh scenarios such as desert high temperature, southern rainy season, and plateau cold. The equipment is equipped with an outdoor high brightness display screen, which provides clear and readable data under strong light. It features a minimalist Chinese operating interface with easy to understand logic, making it easy for beginners to quickly get started and significantly reducing the threshold for using professional testing equipment.

In terms of battery life and data management, the device is adapted to meet the requirements of round the clock batch inspection. Equipped with a large capacity long-lasting lithium battery, it can support up to 8 hours of continuous outdoor operation when fully charged, meeting the full day inspection needs of large-scale photovoltaic bases. The device can store over a thousand sets of complete detection data locally, automatically recording information such as test voltage, measured values, detection time, and device number. It supports USB high-speed export and, when paired with dedicated analysis software, can automatically complete data archiving, trend analysis, and report generation. This makes it easy for operation and maintenance personnel to track changes in the electrical performance of the power station for a long time, providing accurate data support for equipment maintenance and hidden danger rectification. At the same time, the equipment is equipped with high-voltage isolation and automatic discharge modules, which automatically release residual voltage after testing is completed. Combined with multiple protections such as overvoltage, overcurrent, and leakage, it comprehensively ensures the safety of operators and equipment.

Electrical safety is the core bottom line for the stable operation of photovoltaic power plants. LXH601, with its integrated, high-precision, and highly adaptable hard core performance, solves the industry pain points of low efficiency, high cost, and poor accuracy in traditional electrical testing, providing comprehensive electrical safety testing guarantees for new energy equipment such as photovoltaics and energy storage. In the future, LAILX will continue to deeply cultivate the field of new energy electrical safety testing, continuously iterate core technologies, and safeguard the safe and stable operation of photovoltaic power plants throughout their entire lifecycle.
