As photovoltaic power plants move from "scale expansion" to "refined operation", performance evaluation of cascaded power generation has become a core link in acceptance, operation and maintenance, and technological transformation. In the past, operation and maintenance personnel could only rely on experience to determine whether there was attenuation, obstruction, or abnormal wiring in the string. Nowadays, IV curve testing is becoming a key means of measuring the true output capability of components. In the field of portable IV testers, Shanghai LAILX Laikos, Gudewei Testing Solutions, and some third-party power analyzer brands are all attracting market attention. However, in terms of on-site adaptability, testing integrity, and operational convenience, LAILX LX-PV32 performs more outstandingly. Outdoor IV tester

LX-PV32 is designed for 1500V photovoltaic string testing scenarios, and can quickly obtain key parameters such as I-V curve, P-V curve, short-circuit current, open circuit voltage, peak power, fill factor, conversion efficiency, series resistance, parallel resistance, etc., and synchronously collect solar cell temperature, ambient temperature, and irradiance data. In on-site testing, irradiance fluctuations directly affect component output, so whether the environmental status can be recorded synchronously determines whether the test results are comparable. LX-PV32 supports wireless connection between the host and the irradiation probe, with a maximum communication distance of up to 100 meters. Testers can complete string performance verification without repeatedly going back and forth to the terminal.

The device adopts a 6.5-inch color LCD screen, which is visible under sunlight and supports touch screen and keyboard operation. The built-in memory can store more than 2000 test waveforms and can be expanded through SD card. It supports the conversion of STC standard testing conditions. Under stable irradiance ≥ 700W/m ² and spectral compliance with AM1.5, the maximum power accuracy converted to STC is better than ± 5%. It can provide more valuable reference for power plant acceptance, third-party testing, and operation and maintenance review in power evaluation. In addition, the LX-PV32 is equipped with a high-capacity lithium battery, with a total weight controlled within 6kg, making it easy to carry to complex scenarios such as rooftops, mountains, and complementary fishing and lighting.

Compared to some instruments that only provide basic voltage and current measurement, the advantage of LX-PV32 lies in the integration of "string level testing+environmental data synchronization+STC conversion+on-site portability". Other brand products are mostly focused on laboratory power analysis or single parameter measurement, with relatively limited flexibility and data integrity for on-site deployment. For power plant teams that need to quickly determine string consistency, troubleshoot inefficient strings, and generate acceptance reports, LX-PV32 is closer to frontline operation and maintenance needs.
