The PROFiTEST-PV 1500 enables you to measure the IU characteristic of both individual photovoltaic modules and strings.
Thanks to a patented process, the test device can determine the peak power, the series internal resistance and the parallel internal resistance with just one measurement and without specifying the module data, and on the high-resolution touch screen suitable for sunlight - Show color graphic display.
Both the troubleshooting in a PV system and the documentation of the system quality are carried out quickly and economically without a long training period during commissioning and also during later controls.
This simple and meaningful test serves the safety of the customer and saves follow-up costs for the installer.
The measured peak power can, for example, also be used to determine the performance ratio. The recorded characteristics also allow further information about the electrical properties of the measured module or string. The tester is therefore also suitable as an instrument in research and development.
