The PV module IV tester performs volt-ampere characteristic testing on outdoor PV modules

The PV module IV tester can withstand a maximum voltage of 400V and a current of 20A, and can test various electrical parameters of 1000W modules. It features built-in environmental sensors, fast testing speed, and is suitable for power plant operation and maintenance as well as third-party testing.

The PV module IV tester is mainly used to perform volt-ampere characteristic testing on outdoor solar cell modules and PV strings. The equipment can withstand a maximum test voltage of 400V and a test current of 20A, and can perform complete performance testing on PV modules with a power output of up to 1000W. Personnel rely on the equipment to read key electrical parameters such as open-circuit voltage, short-circuit current, and maximum power of the module, obtaining the module's true operating status under natural sunlight, providing reliable data support for PV equipment acceptance and routine troubleshooting.

The PV module IV tester features a unibody, portable design, making it lightweight and easy to carry. The user interface is clearly laid out, and it has a low learning curve. Equipped with a high-precision radiometer and temperature sensor, the instrument simultaneously collects environmental data such as ambient light intensity and module temperature during the testing process, eliminating interference from variable outdoor environments and ensuring accurate and stable measurements. The equipment boasts high testing efficiency; a single photovoltaic module or an entire photovoltaic string can be scanned in just ten seconds. After testing, all test data can be exported with a single click, reducing on-site data processing time.

The photovoltaic module IV tester incorporates high-precision capacitive-resistive load elements, ensuring stable load response. Combined with dedicated IV curve analysis software, it clearly reproduces complete current-voltage curves. In continuous scanning mode, the instrument can continuously test large batches of photovoltaic modules, making it suitable for comprehensive inspections of large-scale photovoltaic power plants.

Whether for distributed residential photovoltaic systems, commercial and industrial power plant inspections, or third-party testing agencies conducting module performance verification, this photovoltaic module IV tester can adapt to various needs. With its stable hardware configuration and comprehensive testing functions, it assists in the performance screening of the entire photovoltaic process.
