FT-IV1 Portable IV Curve Tester: On-Site Performance Testing for Photovoltaic Modules

The IV curve, or current-voltage curve, visually demonstrates the current output of a photovoltaic (PV) cell or module at different voltages. Through this curve, core parameters such as open-circuit voltage, short-circuit current, and maximum power point can be obtained. These parameters are crucial for evaluating PV cell performance, assessing module quality, and determining optimal operating points in system design. For example, during system design, engineers can use IV curves to precisely match inverters and other equipment, ensuring the entire PV system operates efficiently and stably. In component quality inspection, the shape and parameters of the IV curve can quickly reveal issues such as hidden cracks, local contamination, or aging in modules.

The Portable IV Curve Tester is a highly efficient tool specifically designed for on-site performance testing of PV modules. The FT-IV1 is compact and portable, allowing workers to easily carry it to the location of the module being tested in scenarios such as outdoor PV power plant inspections and rapid acceptance of module installations. It features a simple and intuitive operation interface with a user-friendly human-computer interaction experience, enabling users to master its use after brief training.

In terms of configuration, it can perform volt-ampere characteristic tests in low-light outdoor environments and provide corrections for standard STC (Standard Test Conditions). It has a built-in rich database of correction models for solar cell modules, covering products from most module manufacturers, while also offering comprehensive parameter settings for users to manually add test correction models. The internal high-voltage isolated power supply design includes automatic range switching and overvoltage/overcurrent and temperature protection mechanisms to ensure safe operation. Equipped with a large-capacity replaceable lithium-ion battery, it has strong battery life and includes environmental monitoring functions such as panel temperature detection and solar irradiance detection. It can measure a wide range of parameters, including I-V curves, P-V curves, short-circuit current, open-circuit voltage, and maximum power.
