I-V Curve Tracer can measure up to 400V and 20A of current

I-V Curve Tracer can measure 400V voltage and 20A current, supporting 1000W module testing. It is used to measure the open-circuit voltage, short-circuit current, and maximum power of solar cell modules, suitable for photovoltaic power plant operation and maintenance and on-site fault diagnosis.

I-V Curve Tracer is a professional testing device specifically designed for measuring the current-voltage characteristic curve of solar cell modules. It has wide applications in photovoltaic power plant operation and maintenance, module production quality inspection, and scientific research experiments. This device measures and records the output current and voltage values of photovoltaic modules under different conditions by precisely controlling changes in voltage or current, and plots the I-V curve. This curve describes the performance characteristics of photovoltaic modules under different operating states and is crucial for evaluating module performance. The I-V Curve Tracer can test voltages up to 400V and currents up to 20A, capable of testing 1000W photovoltaic modules. It can test parameters such as open-circuit voltage, short-circuit current, and maximum power of solar cell modules or arrays, providing users with a precise and efficient volt-ampere characteristic testing tool.

I-V Curve Tracer device can quickly detect the operating characteristics of photovoltaic (PV) strings under natural sunlight. It is simple to operate, portable, and equipped with a high-precision radiometer and temperature sensor, providing accurate on-site irradiance and ambient temperature parameters. The tester measures the output current of the PV modules at different voltages and plots an I-V curve, which visually presents the performance characteristics of the PV modules under different operating conditions. Based on the I-V curve, key performance parameters of the PV modules can be evaluated, including open-circuit voltage, short-circuit current, maximum power point, and fill factor, thereby determining the module's performance quality. In power plant operation and maintenance, PV modules experience performance degradation due to aging, high temperature, humidity, and other factors over long-term operation. The I-V curve tester can comprehensively capture the current change patterns of the modules under different voltages, providing a complete analysis of the module's power generation capacity, degradation level, and potential faults.
